* ports/nrf: Add micro:bit filesystem.
This filesystem has been copied from BBC micro:bit sources [1] and
modified to work with the nRF5x port.
[1]: https://github.com/bbcmicrobit/micropython/blob/master/source/microbit/filesystem.c
* ports/nrf/modules/uos: Make listdir() and ilistdir() consistent.
This removes the optional direcotry paramter from ilistdir(). This is
not consistent with VFS, but makes more sense when using only the
microbit filesystem.
Saves about 100 bytes.
* ports/nrf/modules/uos: Add code size comment.
* Remove FLASH_ISR and merge .isr_vector into FLASH_TEXT. This saves
some code space, especially on nRF52 devices.
* Reserve space for nonvolatile storage of data. This is the place for
a filesystem (to be added).

ports/nrf: Moving nrf51/52 port to new ports directory
nrf: Aligning with upstream the use of nlr_raise(mp_obj_new_exception_msg(&mp_type_ValueError, ...)
Glenn Ruben Bakke <glennbakke@gmail.com>
nrf/modules/random: Backport of microbit random number generator module
Backport of micro:bit random module.
Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.
Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.
Glenn Ruben Bakke <glennbakke@gmail.com>
nrf/hal/rng: Adding HAL driver for accessing RNG peripheral
The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.
Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).

nrf: Add support for floating point on nrf52 targets.
Duplicating pattern for detecting location of libm, libc and libgcc
from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
and adding libs into the compile. For nrf51 targets it is still set to
NONE as code grows to much (about 30k).
Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

nrf5/boards/feather52: Updating LED pull to low.
nrf5/boards/feather52: Update SPI pinout.
nrf5/main: Move initializaton of modmusic to the module itself. Upon init of the module, the hardware, pwm and ticker will be started. Could be moved back to main if pwm or ticker should be shared among more modules and have to be initialized more global.
nrf5/modules/machine/timer: If timer is used in combination with SOFT_PWM (implicitly use of ticker.c) guard the Timer1 instance from being instantiated trough python timer module. Also disable implementation of the HAL IRQ handler which is for now explicitly implemented in ticker.c for Timer1.

Timer0 is not free if used in combination with a bluetooth stack. Update IRQ priority to levels that are compatible in use with a bluetooth stack for both nrf51 and nrf52. Apply nrf51 PAN fixes for Timer1 instead of original Timer0.
nrf5/drivers/bluetooth: Updating bluetooth driver to initialize nrf_nvic_state_t struct during declaration of the global variable instead of explicit memset.
nrf5/hal/irq: Adding wrappers for handling nvic calls when Bluetooth LE stack is enabled.

nrf5/device: Adding startup files in .c to replace current asm versions.
nrf5/examples: Tuning Bluetooth LE example controller python script after testing out the example live. Motor speed of 100 was not enought to lift the airplane. Also turning was hard without setting higher angle values. The new values are just guessed values. However, the flying experience was good.
nrf5/hal/irq: Adding include of nrf_nvic.h if s132 bluetooth stack is used to resolve IRQ function wrappers on newer bluetooth stacks.
nrf5/drivers/ticker: Removing unused code.
nrf5/examples: Adding music example. Only working if bluetooth stack is not enabled.

nrf5: Adding -fstack-usage flag to gcc CFLAGS to be able to trace stack usage on modules.
nrf5/drivers/ticker: Removing LowPriority callback from nrf51 as there is only one SoftwareIRQ free if bluetooth stack is enabled. Also setting new IRQ priority on SlowTicker to 3 instead of 2, to interleave with bluetooth stack if needed. Updating all NVIC calls to use hal_irq.h defined static inlines instead of direct access.
nrf5/hal/irq: Adding IRQ wrappers if Bluetooth Stack is present.
nrf5: Facilitate option to configure away the modble if needed. Enabled if MICROPY_PY_BLE config is enabled in bluetooth_conf.h.
nrf5/boards/microbit: Enable music module by default. However, timer and rtc module has to be disabled. Bluetooth support broken. Optimization needed.
nrf5/modules/machine: Quickfix. Update timer object to not allow instanciation of Timer(0) if SOFT_PWM is enabled by board.
nrf5/hal/timer: Quickfix. Disable IRQ handler if SOFT_PWM is configured to be enabled. Ticker driver has in current driver a seperate IRQ handler for this timer instance.
nrf5/drivers/ticker: Add compile config guard in ticker.c to only include the driver if SOFT_PWM is configured in by board.
nrf5/drivers/softpwm: Renaming pwm_init to softpwm_init to not collide on symbol name with pwm_init in nrf52 machine PWM object.
nrf5: Add modmusic QSTR definition of notes to qstrdefsport.h.

nrf5: Call microbit_music_init0() if enabled in main.c.
nrf5/modules/music: Expose public init function for music module.
nrf5/modules/music: Update modmusic to use updated includes. Add extern ticks. Add function which implements initialization of pwm and ticker, register ticker callback, and start the pwm and ticker. This corresponds to microbit port main.cpp init.
nrf5/drivers/softpwm: Enable use of ticker in softpwm driver.
nrf5/drivers/ticker: Adding ticker.c/.h from microbit port.
nrf5/drivers/pwm: Renaming pwm.c/.h to softpwm.c/.h
nrf5/drivers/pwm: Expose pwm_init() as public function.
nrf5/modules/ubluepy: Making peripheral conn_handle volatile. Upon connection event, the variable is accessed in thread mode. However, the main-loop is blocking on conn_handle != 0xFFFF. If this is not volatile, optimized code will not exit the loop.
nrf5/drivers/bluetooth: As callback functions are in most usecases are set to NULL upon last event to get public API function out of blocking mode, these function pointers has to be set as volatile, as they are updated to NULL in interrupt context, but read in blocking main-thread.
nrf5/examples: Fixing overlapping function names and variable names inside the object. Also removing some print statements. Tuning max angle from -7/7 to -25/25.

* nrf5/modules/ubluepy: Register central GAP event handler before issuing connect to a peripheral. Has to be done before connect() function as a connected event will be propergated upon successfull connection. The handler will set the connection handle which gets connect function out of the busy loop waiting for connection to succeed.
* nrf5/modules/ubluepy: Removing duplicate setting of GAP event handler in connect().
Glenn Ruben Bakke <glennbakke@gmail.com>

The period of the timer can now be specified using the "period" and
"tick_hz" args. The period in seconds will be: period/tick_hz. tick_hz
defaults to 1000, so if period is specified on its own then it will be in
units of milliseconds.
machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument. The period of
the timer in seconds is: period/tick_hz.
For backwards compatibility tick_hz defaults to 1000. If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000. The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.
An additional freq argument has been added to allow frequencies to be
specified directly in Hertz. This supports floating point values when
available.
Using direct register control as specified by ESP-IDF in
components/esp32/test/test_tsens.c. Temperature doesn't represent any
particular unit, isn't calibrated and will vary from device to device.
Prior to this patch, get_fattime() was calling a HAL RTC function with the
HW instance pointer as null because rtc_init_start() was never called.
Also marked it as a weak function, to allow a board to override it.
With this and previous patches the stm32 port can now be compiled using
object representation D (nan boxing). Note that native code and frozen mpy
files with float constants are currently not supported with this object
representation.
Printing debugging info by defining MICROPY_DEBUG_VERBOSE expects
a definition of the DEBUG_printf function which is readily available
in printf.c so include that file in the build. Before this patch
one would have to manually provide such definition which is tedious.
For the msvc port disable MICROPY_USE_INTERNAL_PRINTF though: the
linker provides no (easy) way to replace printf with the custom
version as defined in printf.c.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.
This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.
This patch allows scripts to have more control over the software WDT. If
an instance of machine.WDT is created then the underlying OS is prevented
from feeding the software WDT, and it is up to the user script to feed it
instead via WDT.feed(). The timeout for this WDT is currently fixed and
will be between 1.6 and 3.2 seconds.
A flash erase/write takes a while and during that time tasks may be
scheduled via an IRQ. To prevent overflow of the task queue (and loss of
tasks) call ets_loop_iter() before and after slow flash operations.
Note: if a task is posted to a full queue while a flash operation is in
progress then this leads to a fault when trying to print out the error
message that the queue is full. This patch doesn't try to fix this
particular issue, it just prevents it from happening in the first place.
This function may be called from a UART IRQ, which may interrupt the system
when it is erasing/reading/writing flash. In such a case all code
executing from the IRQ must be in iRAM (because the SPI flash is busy), so
put mp_keyboard_interrupt in iRAM so ctrl-C can be caught during flash
access.
This patch also takes get_fattime out of iRAM and puts it in iROM to make
space for mp_keyboard_interrupt. There's no real need to have get_fattime
in iRAM because it calls other functions in iROM.
Fixes issue #3897.
Target RAM size is no longer set using Kconfig options, but instead using
DTS (device tree config). Fortunately, the default is now set to a high
value, so we don't need to use DTS fixup.
CONFIG_NET_NBUF_RX_COUNT no longer exists in Zephyr, for a while. That
means we build with the default RX buf count for a while too, and it works,
so just remove it (instead of switching to what it was renamed to,
CONFIG_NET_PKT_RX_COUNT).
The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.
The naming of the module follows (u)hashlib pattern.
At the bare minimum, this module is expected to provide:
* AES128, ECB (i.e. "null") mode, encrypt only
Implementation in this commit is based on axTLS routines, and implements
following:
* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt
Prior to this patch, if both USB FS and HS were enabled via the
configuration file then code was included to handle both of their IRQs.
But mboot only supports listening on a single USB peripheral, so this patch
excludes the code for the USB that is not used.
Only one of pcd_fs_handle/pcd_hs_handle is ever initialised, so if both of
these USB peripherals are enabled then one of these if-statements will
access invalid memory pointed to by an uninitialised Instance. This patch
fixes this bug by explicitly referencing the peripheral struct.
This patch adds support to mboot for programming external SPI flash. It
allows SPI flash to be programmed via a USB DFU utility in the same way
that internal MCU flash is programmed.
Prior to this patch the QSPI driver assumed that the length of all data
reads and writes was a multiple of 4. This patch allows any length. Reads
are optimised for speed by using 32-bit transfers when possible, but writes
always use a byte transfer because they only use a single data IO line and
are relatively slow.
The DMA peripheral is limited to transferring 65535 elements at a time so
in order to send more than that the SPI driver must split the transfers up.
The user must be aware of this limit if they are relying on precise timing
of the entire SPI transfer, because there might be a small delay between
the split transfers.
Fixes issue #3851, and thanks to @kwagyeman for the original fix.
This behaviour of a NULL write C method on a stream that uses the write
adaptor objects is no longer supported. It was only ever used by the
coverage build for testing the fail path of mp_get_stream_raise().
If the user button is held down indefinitely (eg unintenionally, or because
the GPIO signal of the user button is connected to some external device)
then it makes sense to end the reset mode cycle with the default mode of
1, which executes code as normal.
It's possible (at least on F4 MCU's) to have RXNE and STOPF set at the same
time during a call to the slave IRQ handler. In such cases RXNE should be
handled before STOPF so that all bytes are processed before
i2c_slave_process_rx_end() is called.
Due to buffering of outgoing bytes on the I2C bus, detection of a NACK
using the ISR_NACKF flag needs to account for the case where ISR_NACKF
corresponds to the previous-to-previous byte.
This patch renames the existing SPI flash API functions to reflect the fact
that the go through the cache:
mp_spiflash_flush -> mp_spiflash_cache_flush
mp_spiflash_read -> mp_spiflash_cached_read
mp_spiflash_write -> mp_spiflash_cached_write
The DFU USB config descriptor returns 0x0800=2048 for the supported
transfer size, and this applies to both TX (IN) and RX (OUT). So increase
the rx_buf to support this size without having a buffer overflow on
received data.
With this patch mboot in USB DFU mode now works with dfu-util.
Currently <WLAN>.isconnected() always returns True if a static IP is set,
regardless of the state of the connection.
This patch introduces a new flag 'wifi_sta_connected' which is set in
event_handler() when GOT_IP event is received and reset when DISCONNECTED
event is received (unless re-connect is successful). isconnected() now
simply returns the status of this flag (for STA_IF).
The pre-existing flag misleadingly named 'wifi_sta_connected" is also
renamed to 'wifi_sta_connect_requested'.
Fixes issue #3837
MICROPY_PY_DELATTR_SETATTR can now be enabled without a performance hit for
classes that don't use this feature.
MICROPY_PY_BUILTINS_NOTIMPLEMENTED is a minor addition that improves
compatibility with CPython.
They are now efficient (in runtime performance) and provide a useful
feature that's hard to obtain without them enabled.
See issue #3644 and PR #3826 for background.
Now that the coverage build has fully switched to the VFS sub-system these
functions were no longer available, so add them to the uos_vfs module.
Also, vfs_open is no longer needed, it's available as the built-in open.
The unix coverage build is now switched fully to the VFS implementation, ie
the uos module is the uos_vfs module. For example, one can now sandbox uPy
to their home directory via:
$ ./micropython_coverage
>>> import uos
>>> uos.umount('/') # unmount existing root VFS
>>> vfs = uos.VfsPosix('/home/user') # create new POSIX VFS
>>> uos.mount(vfs, '/') # mount new POSIX VFS at root
Some filesystem/OS features may no longer work with the coverage build due
to this change, and these need to be gradually fixed.
The standard unix port remains unchanged, it still uses the traditional uos
module which directly accesses the underlying host filesystem.
This patch adds support for building the firmware with external SPI RAM
enabled. It is disabled by default because it adds overhead (due to
silicon workarounds) and reduces performance (because it's slower to have
bytecode and objects stored in external RAM).
To enable it, either use "make CONFIG_SPIRAM_SUPPORT=1", or add this line
to you custom makefile/GNUmakefile (before "include Makefile"):
CONFIG_SPIRAM_SUPPORT = 1
When this option is enabled the MicroPython heap is automatically allocated
in external SPI RAM.
Thanks to Angus Gratton for help with the compiler and linker settings.
The Wiznet5k series of chips support a MACRAW mode which allows the host to
send and receive Ethernet frames directly. This can be hooked into the
lwIP stack to provide a full "socket" implementation using this Wiznet
Ethernet device. This patch adds support for this feature.
To enable the feature one must add the following to mpconfigboard.mk, or
mpconfigport.mk:
MICROPY_PY_WIZNET5K = 5500
and the following to mpconfigboard.h, or mpconfigport.h:
#define MICROPY_PY_LWIP (1)
After wiring up the module (X5=CS, X4=RST), usage on a pyboard is:
import time, network
nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
nic.active(1)
while not nic.isconnected():
time.sleep_ms(50) # needed to poll the NIC
print(nic.ifconfig())
Then use the socket module as usual.
Compared to using the built-in TCP/IP stack on the Wiznet module, some
performance is lost in MACRAW mode: with a lot of memory allocated to lwIP
buffers, lwIP gives Around 750,000 bytes/sec max TCP download, compared
with 1M/sec when using the TCP/IP stack on the Wiznet module.
It should be up to the NIC itself to decide if the network interface is
removed upon soft reset. Some NICs can keep the interface up over a soft
reset, which improves usability of the network.
Pins with multiple alt-funcs for the same peripheral (eg USART_CTS_NSS)
need to be split into individual alt-funcs for make-pins.py to work
correctly.
This patch changes the following:
- Split `..._CTS_NSS` into `..._CTS/..._NSS`
- Split `..._RTS_DE` into `..._RTS/..._DE`
- Split `JTDO_SWO` into `JTDO/TRACESWO` for consistency
- Fixed `TRACECK` to `TRACECLK` for consistency
If no block devices are defined by a board then storage support will be
disabled. This means there is no filesystem provided by either the
internal flash or external SPI flash. But the VFS system can still be
enabled and filesystems provided on external devices like an SD card.
Mboot is a custom bootloader for STM32 MCUs. It can provide a USB DFU
interface on either the FS or HS peripherals, as well as a custom I2C
bootloader interface.
These files provide no additional information, all the version and license
information is captured in the relevant files in these subdirectories.
Thanks to @JoeSc for the original patch.
This patch allows to use lwIP as the implementation of the usocket module,
instead of the existing socket-multiplexer that delegates the entire TCP/IP
layer to the NIC itself.
This is disabled by default, and enabled by defining MICROPY_PY_LWIP to 1.
When enabled, the lwIP TCP/IP stack will be included in the build with
default settings for memory usage and performance (see
lwip_inc/lwipopts.h). It is then up to a particular NIC to register itself
with lwIP using the standard lwIP netif API.
This patch makes it so that UART(0) can by dynamically attached to and
detached from the REPL by using the uos.dupterm function. Since WebREPL
uses dupterm slot 0 the UART uses dupterm slot 1 (a slot which is newly
introduced by this patch). UART(0) must now be attached manually in
boot.py (or otherwise) and inisetup.py is changed to provide code to do
this. For example, to attach use:
import uos, machine
uart = machine.UART(0, 115200)
uos.dupterm(uart, 1)
and to detach use:
uos.dupterm(None, 1)
When attached, all incoming chars on UART(0) go straight to stdin so
uart.read() will always return None. Use sys.stdin.read() if it's needed
to read characters from the UART(0) while it's also used for the REPL (or
detach, read, then reattach). When detached the UART(0) can be used for
other purposes.
If there are no objects in any of the dupterm slots when the REPL is
started (on hard or soft reset) then UART(0) is automatically attached.
Without this, the only way to recover a board without a REPL would be to
completely erase and reflash (which would install the default boot.py which
attaches the REPL).
Add CONFIG_NET_DHCPV4, which, after
https://github.com/zephyrproject-rtos/zephyr/pull/5750 works as follows:
static addresses are configured after boot, and DHCP requests are sent
at the same time. If valid DHCP reply is received, it overrides static
addresses.
This setup works out of the box for both direct connection to a
workstation (DHCP server usually is not available) and for connection
to a router (DHCP is available and required).
This patch adds the configuration MICROPY_HW_USB_ENABLE_CDC2 which enables
a new USB device configuration at runtime: VCP+VCP+MSC. It will give two
independent VCP interfaces available via pyb.USB_VCP(0) and pyb.USB_VCP(1).
The first one is the usual one and has the REPL on it. The second one is
available for general use.
This configuration is disabled by default because if the mode is not used
then it takes up about 2200 bytes of RAM. Also, F4 MCUs can't support this
mode on their USB FS peripheral (eg PYBv1.x) because they don't have enough
endpoints. The USB HS peripheral of an F4 supports it, as well as both the
USB FS and USB HS peripherals of F7 MCUs.
The documentation (including the examples) for elapsed_millis and
elapsed_micros can be found in docs/library/pyb.rst so doesn't need to be
written in full in the source code.
When disabled, the pyb.I2C class saves around 8k of code space and 172
bytes of RAM. The same functionality is now available in machine.I2C
(for F4 and F7 MCUs).
It is still enabled by default.
This driver uses low-level register access to control the I2C peripheral
(ie it doesn't rely on the ST HAL) and provides the same C-level API as the
existing F7 hardware driver.
- Updated supported git hash to current IDF version.
- Added missing targets and includes to Makefile.
- Updated error codes for networking module.
- Added required constant to sdkconfig configuration.
On this 32-bit arch there's no need to use the long version of the format
specifier. It's only there to appease the compiler which checks the type
of the args passed to printf. Removing the "l" saves a bit of code space.
If a socket is cleanly shut down by the peer then reads on this socket
should continue to return zero bytes. The lwIP socket API does not have
this behaviour (it only returns zero once, then blocks on subsequent calls)
so this patch adds explicit checks and logic for peer closed sockets.
Add --init to the submodule update example, thus, all submodules get
initialised including the nested (--recursive) ones. Without it there
might not be a submodule init.
Disabling this saves around 6000 bytes of code space and gets the 512k
build fitting in the available flash again (it increased lately due to an
increase in the size of the ESP8266 SDK).
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART). Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority. This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.
For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.
This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).
The problem is the existing code which tries to optimise the
reinitialisation of the DMA breaks the abstraction of the HAL. For the
STM32L4 the HAL's DMA setup code maintains two private vars (ChannelIndex,
DmaBaseAddress) and updates a hardware register (CCR).
In HAL_DMA_Init(), the CCR is updated to set the direction of the DMA.
This is a problem because, when using the SD Card interface, the same DMA
channel is used in both directions, so the direction bit in the CCR must
follow that.
A quick and effective fix for the L4 is to simply call HAL_DMA_DeInit() and
HAL_DMA_Init() every time.
ADC3 is used because the H7's internal ADC channels are connected to ADC3
and the uPy driver doesn't support more than one ADC.
Only 12-bit resolution is supported because 12 is hard-coded and 14/16 bits
are not recommended on some ADC3 pins (see errata).
Values from internal ADC channels are known to give wrong values at
present.
The esp8266 uses modlwip.c for its usocket implementation, which allows to
easily support callbacks on socket events (like when a socket becomes ready
for reading). This is not as easy to do for the esp32 which uses the
ESP-IDF-provided lwIP POSIX socket API. Socket events are needed to get
WebREPL working, and this patch provides a way for such events to work by
explicitly polling registered sockets for readability, and then calling the
associated callback if the socket is readable.
After calling HAL_SYSTICK_Config the SysTick IRQ priority is set to 15, the
lowest priority. This commit reconfigures the IRQ priority to the desired
TICK_INT_PRIORITY value.
By default the stm module is included in the build, but a board can now
define MICROPY_PY_STM to 0 to not include this module. This reduces the
firmware by about 7k.
To use HSE bypass mode the board should define:
#define MICROPY_HW_CLK_USE_BYPASS (1)
If this is not defined, or is defined to 0, then HSE oscillator mode is
used.
This patch allows a given board to configure which pins are used for the
CAN peripherals, in a similar way to all the other bus peripherals (I2C,
UART, SPI). To enable CAN on a board the mpconfigboard.h file should
define (for example):
#define MICROPY_HW_CAN1_TX (pin_B9)
#define MICROPY_HW_CAN1_RX (pin_B8)
#define MICROPY_HW_CAN2_TX (pin_B13)
#define MICROPY_HW_CAN2_RX (pin_B12)
And the board config file should no longer define MICROPY_HW_ENABLE_CAN.
The individual union members (like SPI, I2C) are never used, only the
generic "reg" entry is. And the union names can clash with macro
definitions in the HAL so better to remove them.
The only configuration that changes with this patch is that on L4 MCUs the
clock prescaler changed from ADC_CLOCK_ASYNC_DIV2 to ADC_CLOCK_ASYNC_DIV1
for the ADCAll object. This should be ok.
A value of DISABLE for EOCSelection is invalid. This would have been
interpreted instead as ADC_EOC_SEQ_CONV, but really it should be
ADC_EOC_SINGLE_CONV for the uses in this code. So this has been fixed.
ExternalTrigConv should be ADC_SOFTWARE_START because all ADC
conversions are started by software. This is now fixed.
This can be used to select the output buffer behaviour of the DAC. The
default values are chosen to retain backwards compatibility with existing
behaviour.
Thanks to @peterhinch for the initial idea to add this feature.
This event queue has UART events posted to it and they need to be drained
for it to operate without error. The queue is not used by the uPy UART
class so it should be removed to prevent the IDF emitting errors.
Fixes#3704.
This patch moves the implementation of stream closure from a dedicated
method to the ioctl of the stream protocol, for each type that implements
closing. The benefits of this are:
1. Rounds out the stream ioctl function, which already includes flush,
seek and poll (among other things).
2. Makes calling mp_stream_close() on an object slightly more efficient
because it now no longer needs to lookup the close method and call it,
rather it just delegates straight to the ioctl function (if it exists).
3. Reduces code size and allows future types that implement the stream
protocol to be smaller because they don't need a dedicated close method.
Code size reduction is around 200 bytes smaller for x86 archs and around
30 bytes smaller for the bare-metal archs.
The main() function has a predefined type in C which is not so useful for
embedded contexts. This patch renames main() to stm32_main() so we can
define our own type signature for this function. The type signature is
defined to have a single argument which is the "reset_mode" and is passed
through as r0 from Reset_Handler. This allows, for example, a bootloader
to pass through information into the main application.
The Reset_Handler needs to copy the data section and zero the BSS, and
these operations should be as optimised as possible to reduce start up
time. The versions provided in this patch are about 2x faster (on a Cortex
M4) than the previous implementations.
Rather than pin objects themselves. The actual object is now pin_X_obj and
defines are provided so that pin_X is &pin_X_obj. This makes it so that
code that uses pin objects doesn't need to know if they are literals or
objects (that need pointers taken) or something else. They are just
entities that can be passed to the map_hal_pin_xxx functions. This mirrors
how the core handles constant objects (eg mp_const_none which is
&mp_const_none_obj) and allows for the possibility of different
implementations of the pin layer.
For example, prior to this patch there was the following:
extern const pin_obj_t pin_A0;
#define pyb_pin_X1 pin_A0
...
mp_hal_pin_high(&pin_A0);
and now there is:
extern const pin_obj_t pin_A0_obj;
#define pin_A0 (&pin_A0_obj)
#define pyb_pin_X1 pin_A0
...
mp_hal_pin_high(pin_A0);
This patch should have minimal effect on board configuration files. The
only change that may be needed is if a board has .c files that configure
pins.
This patch forces a board to explicitly define TEXT1_ADDR in order to
split the firmware into two separate pieces. Otherwise the default is now
to produce only a single continuous firmware image with all ISR, text and
data together.
This patch allows a particular board to independently specify the linker
scripts for 1) the MCU memory layout; 2) how the different firmware
sections are arranged in memory. Right now all boards follow the same
layout with two separate firmware section, one for the ISR and one for the
text and data. This leaves room for storage (filesystem data) to live
between the firmware sections.
The idea with this patch is to accommodate boards that don't have internal
flash storage and only need to have one continuous firmware section. Thus
the common.ld script is renamed to common_ifs.ld to make explicit that it
is used for cases where the board has internal flash storage.
Explicitly writing out the implementation of sys_tick_has_passed makes
these bdev files independent of systick.c and more reusable as a general
component. It also reduces the code size slightly.
The irq.h header is added to spibdev.c because it uses declarations in that
file (irq.h is usually included implicitly via mphalport.h but not always).
Taking the address assumes that the pin is an object (eg a struct), but it
could be a literal (eg an int). Not taking the address makes this driver
more general for other uses.
genhdr/pins.h is an internal header file that defines all of the pin
objects and it's cleaner to have pin.h include it (where the struct's for
these objects are defined) rather than an explicit include by every user.
The HAL requires strict aliasing optimisation to be turned on to function
correctly (at least for the SD card driver on F4 MCUs). This optimisation
was recently disabled with the addition of H7 support due to the H7 HAL
having errors with the strict aliasing optimisation enabled. But this is
now fixed in the latest stm32lib and so the optimisation can now be
re-enabled.
Thanks to @chuckbook for finding that there was a problem with the SD card
on F4 MCUs with the strict aliasing optimisation disabled.
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc. Prefer
to use these instead of custom ones.
This patch provides a custom (and simple) function to receive data on the
CAN bus, instead of the HAL function. This custom version calls
mp_handle_pending() while waiting for messages, which, among other things,
allows to interrupt the recv() method via KeyboardInterrupt.
Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver. To work
around this make the pin an input to let it float high.
This config variable controls whether to support storage on the internal
flash of the MCU. It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.
It makes it cleaner, and simpler to support multiple different block
devices. It also allows to easily extend a given block device with new
ioctl operations.
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h). This allows the SPI-flash driver to
be used independently from the uPy runtime.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c. This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.
The PWM at full value was not considered as an "active" channel so if no
other channel was used the timer used to mange PWM was not started. So
when another duty value was set the PWM timer restarted and there was a
visible glitch when driving LEDs. Such a glitch can be seen with the
following code (assuming active-low LED on pin 0):
p = machine.PWM(machine.Pin(0))
p.duty(1023) # full width, LED is off
p.duty(1022) # LED flashes brightly then goes dim
This patch fixes the glitch.
This test for calling gc_realloc() while the GC is locked can be done in
pure Python, so better to do it that way since it can then be tested on
more ports.
These new tests cover cases that can't be reached from Python and get
coverage of py/mpz.c to 100%.
These "unreachable from Python" pieces of code could be removed but they
form an integral part of the mpz C API and may be useful for non-Python
usage of mpz.
These ports don't need anything from extmod so don't include those files
at all in the build. This speeds up the build by about 10% when building
with a single core.
Currently only the first 2 args are used, but this patch should at least
make getaddrinfo() signature-compatible with CPython and other bare-metal
ports that use the lwip bindings.
Prior to this patch, storage.c was a combination of code that handled
either internal flash or external SPI flash and exposed one of them as a
block device for the local storage. It was also exposed to the USB MSC.
This patch splits out the flash and SPI code to separate files, which each
provide a general block-device interface (at the C level). Then storage.c
just picks one of them to use as the local storage medium. The aim of this
factoring is to allow to add new block devices in the future and allow for
easier configurability.
This patch allows to completely compile-out support for USB, and no-USB is
now the default. If a board wants to enable USB it should define:
#define MICROPY_HW_ENABLE_USB (1)
And then one or more of the following to select the USB PHY:
#define MICROPY_HW_USB_FS (1)
#define MICROPY_HW_USB_HS (1)
#define MICROPY_HW_USB_HS_IN_FS (1)
Newer versions of the HAL use names which are cleaner and more
self-consistent amongst the HAL itself. This patch switches to use those
names in most places so it is easier to update the HAL in the future.
Prior to this patch the USBD driver did not handle the recipient correctly
for setup requests. It was not interpreting the req->wIndex field in the
right way: in some cases this field indicates the endpoint number but the
code was assuming it always indicated the interface number.
This patch fixes this. The only noticeable change is to the MSC
interface, which should now correctly respond to the USB_REQ_CLEAR_FEATURE
request and hence unmount properly from the host when requested.
mpconfigboard_common.h now sets the defaults so there is no longer a need
to explicitly list all configuration options in a board's mpconfigboard.h
file.
This file mirrors py/mpconfig.h but for board-level config options. It
provides a default configuration, to be overridden by a specific
mpconfigboard.h file, as well as setting up certain macros to automatically
configure a board.
The calls to rtc_init_start(), sdcard_init() and storage_init() are all
guarded by a check for first_soft_reset, so it's simpler to just put them
all before the soft-reset loop, without the check.
The call to machine_init() can also go before the soft-reset loop because
it is only needed to check the reset cause which can happen once at the
first boot. To allow this to work, the reset cause must be set to SOFT
upon a soft-reset, which is the role of the new function machine_deinit().
Upon boot the RTC early-init function should detect if LSE or LSI is
already selected/running and, if so, use it. When the LSI has previously
(in the previous reset cycle) been selected as the clock source the only
way to reliably tell is if the RTCSEL bits of the RCC_BDCR are set to the
correct LSI value. In particular the RCC_CSR bits for LSI control do not
indicate if the LSI is ready even if it is selected.
This patch removes the check on the RCC_CSR bits for the LSI being on and
ready and only uses the check on the RCC_BDCR to see if the LSI should be
used straightaway. This was tested on a PYBLITEv1.0 and with the patch the
LSI persists correctly as the RTC source as long as the backup domain
remains powered.
Previously, if LSE is selected but fails and the RTC falls back to LSI,
then the rtc_info flags would incorrectly state that LSE is used. This
patch fixes that by setting the bit in rtc_info only after the clock is
ready.
There is an underlying hardware SPI driver (built on top of the STM HAL)
and then on top of this sits the legacy pyb.SPI class as well as the
machine.SPI class. This patch improves the separation between these
layers, in particular decoupling machine.SPI from pyb.SPI.
The SPI sub-system is independent from the uPy state (eg the heap) and so
can safely persist across a soft reset. And this is actually necessary for
drivers that rely on SPI and that also need to persist across soft reset
(eg external SPI flash memory).
This patch adds support in the USBD configuration and CDC-MSC-HID class for
high-speed USB mode. To enable it the board configuration must define
USE_USB_HS, and either not define USE_USB_HS_IN_FS, or be an STM32F723 or
STM32F733 MCU which have a built-in HS PHY. High-speed mode is then
selected dynamically by passing "high_speed=True" to the pyb.usb_mode()
function, otherwise it defaults to full-speed mode.
This patch has been tested on an STM32F733.
By defining MICROPY_HW_USB_MAIN_DEV a given board can select to use either
USB_PHY_FS_ID or USB_PHY_HS_ID as the main USBD peripheral, on which the
REPL will appear. If not defined this will be automatically configured.
There's no need to have these as separate functions, they just take up
unnecessary code space and combining them allows to factor common code, and
also allows to support arbitrary string descriptor indices.
The routine waits for the DMA to finish, which is signalled from a DMA IRQ
handler. Using WFI makes the CPU sleep while waiting for the IRQ to arrive
which decreases power consumption. To make it work correctly the check for
the change in state must be atomic and so IRQs must be disabled during the
check. The key feature of the Cortex MCU that makes this possible is that
WFI will exit when an IRQ arrives even if IRQs are disabled.
Build and test 32bit and 64bit versions of the windows port using gcc
from mingw-w64. Note a bunch of tests which rely on floating point
math/printing have been disabled for now since they fail.
The number of registers used should be 10, not 12, to match the assembly
code in nlrx64.c. With this change the 64bit mingw builds don't need to
use the setjmp implementation, and this fixes miscellaneous crashes and
assertion failures as reported in #1751 for instance.
To avoid mistakes in the future where something gcc-related for Windows
only gets fixed for one particular compiler/environment combination,
make use of a MICROPY_NLR_OS_WINDOWS macro.
To make sure everything nlr-related is now ok when built with gcc this
has been verified with:
- unix port built with gcc on Cygwin (i686-pc-cygwin-gcc and
x86_64-pc-cygwin-gcc, version 6.4.0)
- windows port built with mingw-w64's gcc from Cygwin
(i686-w64-mingw32-gcc and x86_64-w64-mingw32-gcc, version 6.4.0)
and MSYS2 (like the ones on Cygwin but version 7.2.0)
Add some features which are already enabled in the unix port and
default to using the Python stack for scoped allocations: this can be
more performant in cases the heap is heavily used because for example
the memory needed for storing *args and **kwargs doesn't require
scanning the heap to find a free block.
For MSVC off_t is defined in sys/types.h but according to the comment
earlier in mpconfigport.h this cannot be included directly.
So just make off_t the same as mp_off_t.
This fixes the build for MSVC with MICROPY_STREAMS_POSIX_API
enabled because stream.h uses off_t.
These were copied from the stm32 port (then stmhal) at the very beginning
of this port, with the anticipation that the esp8266 port would have board
definition files with a list of valid pins and their names. But that has
not been implemented and likely won't be, so remove the corresponding lines
from the Makefile.
This patch adds in internal config value MICROPY_HW_ENABLE_HW_I2C that is
automatically configured, and enabled only if one or more hardware I2C
ports are defined in the mpconfigboard.h file. If none are defined then
the pyb.I2C class is excluded from the build, along with all supporting
code. The machine.I2C class will still be available for software I2C.
Disabling all hardware I2C on an F4 board saves around 10,000 bytes of code
and 200 bytes of RAM.
If TEST is defined, file it refers to will be used as the testsuite
source (should be generated with tools/tinytest-codegen.py).
"make-bin-testsuite" script is introduce to build such a binary.
Because otherwise the function can return with data still waiting to be
clocked out, and CS might then be disabled before the SPI transaction is
complete. Fixes issue #3487.
The way tinytest was used in qemu-arm test target is that it didn't test
much. MicroPython tests are based on matching the test output against
reference output, but qemu-arm's implementation didn't do that, it
effectively tested just that there was no exception during test
execution. "upytesthelper" wrapper was introduce to fix it, so switch
test implementation to use it.
This requires passing different CFLAGS when building the firmware, so
split out test-related parts to Makefile.test.
Code lineage:
osdebug() is based loosely on the version in esp8266, but there didn't
seem to be an obvious way of choosing a particular UART. The basic
behavior is the same, though: provide None, and logging is disabled;
provide an integer and logging is restored to the default level.
To build on that, and because the IDF provides more functionality, a
second parameter has now been implemented which allows the active log
level to be set:
esp.osdebug(uart[, level])
The module has a corresponding set of LOG_ values to set this accordingly.
When configuring a static set of values with ifconfig() the DNS was not
being set. This patch fixes that, and additionally uses the tcpip_adapter
API to ensure it is thread safe.

understand the SDK's API for PWM). So aside from the code copied from the
esp8266 PWM support, everything else you see is just new code I wrote.
I wasn't an employee of anybody when I wrote it, and I wrote it with the
understanding and intention that it's simply a derivative work of the
existing micropython code. I freely and willingly contribute it to the
project and intend that it not change the legal status of the micropython
code base in any way, even if it is included in that base in whole or part.

This function was implemented as an experiment, and was enabled only in
unix port. To remind, it allows to access arbitrary files frozen as
source modules (vs bytecode).
However, further experimentation showed that the same functionality can
be implemented with frozen bytecode. The process requires more steps, but
with suitable toolset it doesn't matter patch. This process is:
1. Convert binary files into "Python resource module" with
tools/mpy_bin2res.py.
2. Freeze as the bytecode.
3. Use micropython-lib's pkg_resources.resource_stream() to access it.
In other words, the extra step is using tools/mpy_bin2res.py (because
there would be wrapper for uio.resource_stream() anyway).
Going frozen bytecode route allows more flexibility, and same/additional
efficiency:
1. Frozen source support can be disabled altogether for additional code
savings.
2. Resources could be also accessed as a buffer, not just as a stream.
There're few caveats too:
1. It wasn't actually profiled the overhead of storing a resource in
"Python resource module" vs storing it directly, but it's assumed that
overhead is small.
2. The "efficiency" claim above applies to the case when resource
file is frozen as the bytecode. If it's not, it actually will take a
lot of RAM on loading. But in this case, the resource file should not
be used (i.e. generated) in the first place, and micropython-lib's
pkg_resources.resource_stream() implementation has the appropriate
fallback to read the raw files instead. This still poses some distribution
issues, e.g. to deployable to baremetal ports (which almost certainly
would require freezeing as the bytecode), a distribution package should
include the resource module. But for non-freezing deployment, presense
of resource module will lead to memory inefficiency.
All the discussion above reminds why uio.resource_stream() was implemented
in the first place - to address some of the issues above. However, since
then, frozen bytecode approach seems to prevail, so, while there're still
some issues to address with it, this change is being made.
This change saves 488 bytes for the unix x86_64 port.
Command-line argc and argv should be passed, and as we don't have them,
placeholders were passed, but incorrectly. As we don't have them, just
pass 0/NULL. Looking at the source, this migh lead to problems under
Windows, but this test doesn't run under Windows.
Also, use "%d" printf format consistently with the rest of the codebase.
Prior to this fix, enabling WebREPL for the first time via webrepl_setup
did not work at all because "boot.py" did not contain any lines with
"webrepl" in them that could be uncommented.
This time hopefully should work reliably, using make $(wildcard) function,
which in this case either expands to existing prj_$(BOARD).conf file, or to
an empty string for non-existing one.
This is a low-cost evaluation kit board from ST based on the STM32
Nucleo-144 form factor. It uses the STM32F746ZG MCU in the LQFP144
package. The MCU has 1MB of flash and 320kB of System RAM.
Cortex-M7 runs at up to 216MHz.
This patch simplifies the str creation API to favour the common case of
creating a str object that is not forced to be interned. To force
interning of a new str the new mp_obj_new_str_via_qstr function is added,
and should only be used if warranted.
Apart from simplifying the mp_obj_new_str function (and making it have the
same signature as mp_obj_new_bytes), this patch also reduces code size by a
bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).
The SHA1 hashing functionality is provided via the "axtls" library's
implementation, and hence is unavailable when the "axtls" library is not being
used. This change provides the same SHA1 hashing functionality when using the
"mbedtls" library by using its implementation instead.
Macros to convert big-endian values to host byte order and vice-versa.
These were defined in adhoc way for some ports (e.g. esp8266), allow
reuse, provide default implementations, while allow ports to override.
In the vendor SDK 2.1.0, some of the functions which previously didn't
have prototypes, finally acquired them. Change prototypes on our side
to match those in vendor headers, to avoid warnings-as-errors.
With inplace methods now disabled by default, it makes sense to enable
reverse methods, as they allow for more useful features, e.g. allow
for datetime module to implement both 2 * HOUR and HOUR * 2 (where
HOUR is e.g. timedelta object).
Unix naming is historical, before current conventions were established.
All other ports however have it as "modusocket.c", so rename for
consistency and to avoid confusion.
The legacy function pyb.repl_uart() is still provided and retains its
original behaviour (it only accepts a UART object). uos.dupterm() will now
accept any object with write/readinto methods. At the moment there is just
1 dupterm slot.
The W5200 and W5500 can support up to 80MHz so 42MHz (the maximum the
pyboard can do in its standard configuration) should be safe.
Tested to give around 1050000 kbytes/sec TCP download speed on a W5500,
which is about 10% more than with the previous SPI speed of 21MHz.
Which Wiznet chip to use is a compile-time option: MICROPY_PY_WIZNET5K
should be set to either 5200 or 5500 to support either one of these
Ethernet chips. The driver is called network.WIZNET5K in both cases.
Note that this commit introduces a breaking-change at the build level
because previously the valid values for MICROPY_PY_WIZNET5K were 0 and 1
but now they are 0, 5200 and 5500.
The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs. It has minor backwards incompatibility in that
it no longer accepts zero arguments.
The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.
A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.
The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.
While this console API improves handling on real hardware boards
(e.g. clipboard paste is much more reliable, as well as programmatic
communication), it vice-versa poses problems under QEMU, apparently
because it doesn't emulate UART interrupt handling faithfully. That
leads to inability to run the testsuite on QEMU at all. To work that
around, we have to suuport both old and new console routines, and use
the old ones under QEMU.
Ideally, these should be configurable from Python (using network module),
but as that doesn't exist, we better off using Zephyr's native bootstrap
configuration facility.
Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.
This adds a new configuration option to print runtime warnings and errors to
stderr. On Unix, CPython prints warnings and unhandled exceptions to stderr,
so the unix port here is configured to use this option.
The unix port already printed unhandled exceptions on the main thread to
stderr. This patch fixes unhandled exceptions on other threads and warnings
(issue #2838) not printing on stderr.
Additionally, a couple tests needed to be fixed to handle this new behavior.
This is done by also capturing stderr when running tests.
The timer prescaler is buffered by default, and this patch enables ARPE
which buffers the auto-reload register. With both of these registers
buffered it's now possible to smoothly change the timer's frequency and
have a smoothly varying PWM output.
Current users of fixed vstr buffers (building file paths) assume that there
is no overflow and do not check for overflow after building the vstr. This
has the potential to lead to NULL pointer dereferences
(when vstr_null_terminated_str returns NULL because it can't allocate RAM
for the terminating byte) and stat'ing and loading invalid path names (due
to the path being truncated). The safest and simplest thing to do in these
cases is just raise an exception if a write goes beyond the end of a fixed
vstr buffer, which is what this patch does. It also simplifies the vstr
code.
Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one. This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.
The patch also refactors the way timers are validated on construction to
simplify and reduce code size.
If, for class X, X.__add__(Y) doesn't exist (or returns NotImplemented),
try Y.__radd__(X) instead.
This patch could be simpler, but requires undoing operand swap and
operation switch to get non-confusing error message in case __radd__
doesn't exist.
connect, send, recv, sendto and recvfrom now release the GIL. accept
already releases the GIL because it calls mp_hal_delay_ms() within its
busy-wait loop.
Previous to this patch the i2c.scan() method would do up to 100 probes per
I2C address, to detect the devices on the bus. This repeated probing was a
relic from when the code was copied from the accelerometer initialisation,
which requires to do repeated probes while waiting for the accelerometer
chip to turn on.
But I2C devices shouldn't need more than 1 probe to detect their presence,
and the generic software I2C implementation uses 1 probe successfully. So
this patch changes the implementation to use 1 probe per address, which
significantly speeds up the scan operation.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
