Chris Mason eb12fa3862 stm32/powerctrlboot: Add support for HSI at 8MHz on F0 MCUs.
For use with F0 MCUs that don't have HSI48.  Select the clock source
explicitly in mpconfigboard.h.

On the NUCLEO_F091RC board use HSE bypass when HSE is chosen because the
NUCLEO clock source is STLINK not a crystal.

Chris Mason f16e4be3fa stm32/powerctrlboot: Fix clock and PLL selection for HSI48 on F0 MCUs.
Before this patch the UART baudrate on F0 MCUs was wrong because the
stm32lib SystemCoreClockUpdate sets SystemCoreClock to 8MHz instead of
48MHz if HSI48 is routed directly to SYSCLK.

The workaround is to use HSI48 -> PREDIV (/2) -> PLL (*2) -> SYSCLK.

Fixes issue #5049.

    pyb.USB_VCP().init(flow=pyb.USB_VCP.RTS | pyb.USB_VCP.CTS)

iabdalkader 4f78ba3cf4 stm32/boards/NUCLEO_H743ZI: Enable FDCAN on this board. 2019-09-23 17:00:54 +10:00
iabdalkader f7a07b3605 stm32: Add support for FDCAN peripheral, exposed as pyb.CAN.
The new fdcan.c file provides the low-level C interface to the FDCAN
peripheral, and pyb_can.c is updated to support both traditional CAN and
FDCAN, depending on the MCU being compiled for.

Damien George d06fd384c2 stm32/can: Factor CAN driver into low-level and Python bindings.

stijn d96391aca3 mpy-cross,windows: Add msvc build of mpy-cross.
Add the project file to the mpy-cross directory, which is also where the
executable ends up, and change the Appveyor settings to build mpy-cross
with both msvc and mingw-w64 and verify this all works by running tests
with --via-mpy.
2019-09-18 22:16:36 +10:00
stijn bc86c6252a windows: Default to binary mode for files.
If this is not set it might default to calls to open() to use text mode
which is usually not wanted, and even wrong and leading to incorrect
results when loading binary .mpy files.

This also means that text files written and read will not have line-ending
translation from \n to \r\n and vice-versa anymore.  This shouldn't be much
of a problem though since most tools dealing with text files adapt
automatically to any of the 2 formats.
2019-09-18 22:15:48 +10:00
stijn 6957939604 windows/msvc: Change the way sources are listed.
Reserve sources.props for listing just the MicroPython core and extmod
files, similar to how py.mk lists port-independent source files.  This
allows reusing the source list, for instance for building mpy-cross.  The
sources for building the executable itself are listed in the corresponding
project file, similar to how the other ports specify the source files in
their Makefile.
2019-09-18 22:15:10 +10:00
stijn 146c32a141 windows/msvc: Enable overriding directories used in the build.
Append to PyIncDirs, used to define include directories specific to
MicroPython, instead of just overwriting it so project files importing this
file can define additional directories.  And allow defining the target
directory for the executable instead of hardcoding it to the windows
directory.  Main reason for this change is that it will allow building
mpy-cross with msvc.
2019-09-18 22:14:37 +10:00
stijn 94873a4826 windows/msvc: Move build options from .vcxproj to .props files.
We want the .vcxproj to be just a container with the minimum content for
making it work as a project file for Visual Studio and MSBuild, whereas the
actual build options and actions get placed in separate reusable files.
This was roughly the case already except some compiler options were
overlooked; fix this here: we'll need those common options when adding a
project file for building mpy-cross.
2019-09-18 22:14:11 +10:00
stijn b2b21839d3 windows/msvc: Remove unneeded definitions for qstr generation.
These were probably added to detect more qstrs but as long as the
micropython executable itself doesn't use the same build options the qstrs
would be unused anyway.  Furthermore these definitions are for internal use
and get enabled when corresponding MICROPY_EMIT_XXX are defined, in which
case the compiler would warn about symbol redefinitions since they'd be
defined both here and in the source.

Jim Mussared 96008ff59a esp32: Support building with ESP IDF 4.0-beta1.
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag).  When this hash is detected, the relevant changes are
applied.

This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.

Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.

Damien George b45f9de809 bare-arm, minimal: Set CSUPEROPT=-Os to get minimal firmware size.
This option affects py/vm.c and py/gc.c and using -Os gets them compiling a
bit smaller, and small firmware is the aim of these two ports.  Also,
having these files compiled with -Os on these ports, and -O3 as the default
on other ports, gives a better understanding of code-size changes when
making changes to these files.

Damien George f66616556d stm32/lwip_inc: Enable LWIP_NETIF_EXT_STATUS_CALLBACK for mDNS.
This feature makes sure that mDNS is automatically restarted when there is
any change event on a netif.
2019-09-12 18:08:50 +10:00
Damien George b0e17bbb9d stm32/lwip_inc: Allocate additional MEMP_SYS_TIMEOUT when mDNS enabled.
Since v2.1 of lwIP mDNS uses a MEMP_SYS_TIMEOUT slot, so allocate an extra
one when this feature is enabled.

Alex Albino 80d37d936c esp32: Add support for ESP32-D2WD with 2MiB internal flash.
This patch adds a partitions file for the D2WD and a new board GENERIC_D2WD
which runs on these chip variants.

Resolves issue #4986.

Damien George 31de44775c esp32: Add VFS FAT partition to partitions.csv and mount it as the FS.
This patch uses the newly-added esp32.Partition class to replace the
existing FlashBdev class.  Partition objects implement the block protocol
so can be directly mounted via uos.mount().  This has the following
benefits:

- allows the filesystem partition location and size to be specified in
  partitions.csv, and overridden by a particular board
- very easily allows to have multiple filesystems by simply adding extra
  entries to partitions.csv
- improves efficiency/speed of filesystem operations because the block
  device is implemented fully in C
- opens the possibility to have encrypted flash storage (since Partitions
  can be encrypted)

Note that this patch is fully backwards compatible: existing filesystems
remain untouched and work with this new code.

Chris Wilson a605b53702 stm32/mboot: Support boards with only two LEDs.
Mboot currently requires at least three LEDs to display each of the four

be displayed via binary counting on only 2 LEDs (if only 2 are available).
The existing patterns are still used for 3 or 4 LEDs.

Jim Mussared 353ed7705f nrf/boards/make-pins.py: Fix gen of board pins to use correct index.
It was previously not taking into account that the list of pins was sparse,

As part of this fix rename the variables to make it more clear what the
list contains (only board pins).

top-level script.

In the future there could be a way to also set this variable from a script.

Damien George 3eff81288c stm32/i2c: Fix generation of restart condition for hw I2C on F0/F7.
Before this patch I2C transactions using a hardware I2C peripheral on F0/F7
MCUs would not correctly generate the I2C restart condition, and instead
would generate a stop followed by a start.  This is because the CR2 AUTOEND
bit was being set before CR2 START when the peripheral already had the I2C
bus from a previous transaction that did not generate a stop.

As a consequence all combined transactions, eg read-then-write for an I2C
memory transfer, generated a stop condition after the first transaction and
didn't generate a stop at the very end (but still released the bus).  Some
I2C devices require a repeated start to function correctly.

This patch fixes this by making sure the CR2 AUTOEND bit is set after the
start condition and slave address have been fully transferred out.

Kenta IDA b6906fa573 esp32/network_ppp: Add authentication support to the PPP interface.
This commit adds the connect() method to the PPP interface and requires
that connect() be called after active(1).  This is a breaking change for
the PPP API.

With the connect() method it's now possible to pass in authentication
information for PAP/CHAP, eg:

    ppp.active(1)
    ppp.connect(authmode=ppp.AUTH_PAP, username="user", "password="password")

If no authentication is needed simply call connect() without any
parameters.  This will get the original behaviour of calling active(1).

Damien George fa07deda9f stm32/usbd_hid_interface: Rewrite USB HID interface code.
The previous version did not work on MCUs that only had USB device mode
(compared to OTG) because of the handling of NAK.  And this previous
handling of NAK had a race condition where a new packet could come in
before USBD_HID_SetNAK was called (since USBD_HID_ReceivePacket clears NAK
as part of its operation).  Furthermore, the double buffering of incoming
reports was not working, only one buffer could be used at a time.

This commit rewrites the HID interface code to have a single incoming
buffer, and only calls USBD_HID_ReceivePacket after the user has read the
incoming report (similar to how the VCP does its flow control).  As such,
USBD_HID_SetNAK and USBD_HID_ClearNAK are no longer needed.

API functionality from the user's point of view should be unchanged with
this commit.

Amir Gonnen 995f9cfdfc esp32: Pin MicroPython tasks to a specific core.
On this port the GIL is enabled and everything works under the assumption
of the GIL, ie that a given task has exclusive access to the uPy state, and
any ISRs interrupt the current task and therefore the ISR inherits
exclusive access to the uPy state for the duration of its execution.

If the MicroPython tasks are not pinned to a specific core then an ISR may
be executed on a different core to the task, making it possible for the
main task and an ISR to execute in parallel, breaking the assumption of the
GIL.

The easiest and safest fix for this is to pin all MicroPython related code
to the same CPU core, as done by this patch.  Then any ISR that accesses
MicroPython state must be registered from a MicroPython task, to ensure it
is invoked on the same core.

See issue #4895.

Damien George 8da39fd182 stm32/qspi: Use MPU to allow access to valid memory-mapped QSPI region.
The Cortex-M7 CPU will do speculative loads from any memory location that
is not explicitly forbidden.  This includes the QSPI memory-mapped region
starting at 0x90000000 and with size 256MiB.  Speculative loads to this
QSPI region may 1) interfere with the QSPI peripheral registers (eg the
address register) if the QSPI is not in memory-mapped mode; 2) attempt to
access data outside the configured size of the QSPI flash when it is in
memory-mapped mode.  Both of these scenarios will lead to issues with the
QSPI peripheral (eg Cortex bus lock up in scenario 2).

To prevent such speculative loads from interfering with the peripheral the
MPU is configured in this commit to restrict access to the QSPI mapped
region: when not memory mapped the entire region is forbidden; when memory
mapped only accesses to the valid flash size are permitted.

Damien George 04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

Damien George 53200247b7 stm32/usb: Add "msc" kw-arg to pyb.usb_mode to select MSC logical units.
With this the user can select multiple logical units to expose over USB MSC

Damien George ce8262a164 stm32/modnetwork: Replace generic netif NIC polling with specific code.
It doesn't work to tie the polling of an underlying NIC driver (eg to check
the NIC for pending Ethernet frames) with its associated lwIP netif.  This
is because most NICs are implemented with IRQs and don't need polling,
because there can be multiple lwIP netif's per NIC driver, and because it
restricts the use of the netif->state variable.  Instead the NIC should
have its own specific way of processing incoming Ethernet frame.

This patch removes this generic NIC polling feature, and for the only
driver that uses it (Wiznet5k) replaces it with an explicit call to the
poll function (which could eventually be improved by using a proper
external interrupt).

Martin Dybdal de76f73d34 esp32/machine_timer: Reuse Timer handles, deallocate only on soft-reset.
The patch solves the problem where multiple Timer objects (e.g. multiple
Timer(0) instances) could initialise multiple handles to the same internal
timer.  The list of timers is now maintained not for "active" timers (where
init is called), but for all timers created.  The timers are only removed
from the list of timers on soft-reset (machine_timer_deinit_all).

Damien George b8c74014e4 stm32/usbd_cdc_interface: Don't retransmit chars if USB is reconnected.
Before this change, if the USB was reconnected it was possible that some
characters in the TX buffer were retransmitted because tx_buf_ptr_out and
tx_buf_ptr_out_shadow were reset while tx_buf_ptr_in wasn't.  That
behaviour is fixed here by retaining the TX buffer state across reconnects.

Damien George 97753a1bbc stm32: Move factory reset files and code to separate source file.
The new function factory_reset_make_files() populates the given filesystem
with the default factory files.  It is defined with weak linkage so it can
be overridden by a board.

This commit also brings some minor user-facing changes:

- boot.py is now no longer created unconditionally if it doesn't exist, it
  is now only created when the filesystem is formatted and the other files
  are populated (so, before, if the user deleted boot.py it would be
  recreated at next boot; now it won't be).

- pybcdc.inf and README.txt are only created if the board has USB, because
  they only really make sense if the filesystem is exposed via USB.

Damien George 34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

gc_collect() and gc_collect_regs_and_stack() get inlined into gc_alloc()
which can result in the regs variable being pushed on the stack earlier
than some of the registers. Depending on the calling convention, those
registers might however contain pointers to blocks which have just been
allocated in the caller of gc_alloc(). Then those pointers end up higher on
the stack than regs, aren't marked by gc_collect_root() and hence get
sweeped, even though they're still in use.

As reported in #4652 this happened for in 32-bit msvc release builds:
mp_lexer_new() does two consecutive allocations and the latter triggered a
gc_collect() which would sweep the memory of the first allocation again.

Krono fbd4e61e57 esp32/machine_wdt: Add timeout arg to select interval, make WDT panic.
The machine.WDT() now accepts the "timeout" keyword argument to select the
WDT interval.  And the WDT is changed to panic mode which means it will
reset the device if the interval expires (instead of just printing an error
message).

Damien George 8031b7a25c stm32/powerctrl: Deselect PLLSAI as 48MHz src before turning off PLLSAI.
On the STM32F722 (at least, but STM32F767 is not affected) the CK48MSEL bit
must be deselected before PLLSAION is turned off, or else the 48MHz
peripherals (RNG, SDMMC, USB) may get stuck without a clock source.

In such "lock up" cases it seems that these peripherals are still being
clocked from the PLLSAI even though the CK48MSEL bit is turned off.  A hard
reset does not get them out of this stuck state.  Enabling the PLLSAI and
then disabling it does get them out.  A test case to see this is:

    import machine, pyb
    for i in range(100):
        machine.freq(122_000000)
        machine.freq(120_000000)
        print(i, [pyb.rng() for _ in range(4)])

On occasion the RNG will just return 0's, but will get fixed again on the
next loop (when PLLSAI is enabled by the change to a SYSCLK of 122MHz).

Fixes issue #4696.

Damien George 0646e607b5 ports: Convert to use pyexec_file_if_exists() to execute boot/main.py.
The stm32 and nrf ports already had the behaviour that they would first
check if the script exists before executing it, and this patch makes all
other ports work the same way.  This helps when developing apps because
it's hard to tell (when unconditionally trying to execute the scripts) if
the resulting OSError at boot up comes from missing boot.py or main.py, or
from some other error.  And it's not really an error if these scripts don't
exist.

Damien George aa7b32c811 stm32/dac: Rework DAC driver to use direct register access.
This patch makes the DAC driver simpler and removes the need for the ST
HAL.  As part of it, new helper functions are added to the DMA driver,
which also use direct register access instead of the ST HAL.

Main changes to the DAC interface are:

- The DAC uPy object is no longer allocated dynamically on the heap,
  rather it's statically allocated and the same object is retrieved for
  subsequent uses of pyb.DAC(<id>).  This allows to access the DAC objects
  without resetting the DAC peripheral.  It also means that the DAC is only
  reset if explicitly passed initialisation parameters, like "bits" or
  "buffering".

- The DAC.noise() and DAC.triangle() methods now output a signal which is
  full scale (previously it was a fraction of the full output voltage).

- The DAC.write_timed() method is fixed so that it continues in the
  background when another peripheral (eg SPI) uses the DMA (previously the
  DAC would stop if another peripheral finished with the DMA and shut the
  DMA peripheral off completely).

Based on the above, the following backwards incompatibilities are
introduced:

- pyb.DAC(id) will now only reset the DAC the first time it is called,
  whereas previously each call to create a DAC object would reset the DAC.
  To get the old behaviour pass the bits parameter like: pyb.DAC(id, bits).

- DAC.noise() and DAC.triangle() are now full scale.  To get previous
  behaviour (to change the amplitude and offset) write to the DAC_CR (MAMP
  bits) and DAC_DHR12Rx registers manually.

Maureen Helm 2befcb8a9d zephyr/i2c: Add support for hardware i2c.
Adds support for hardware i2c to the zephyr port. Similar to other ports
such as stm32 and nrf, we only implement the i2c protocol functions
(readfrom and writeto) and defer memory operations (readfrom_mem,
readfrom_mem_into, and writeto_mem) to the software i2c implementation.
This may need to change in the future because zephyr is considering
deprecating its i2c_transfer function in favor of i2c_write_read; in this
case we would probably want to implement the memory operations directly
using i2c_write_read.

Tested with the accelerometer on frdm_k64f and bbc_microbit boards.

Damien George f8f2724297 stm32/qspi: Enable sample shift and disable timeout counter.
This makes the QSPI more robust, in particular the timeout counter should

Petr Kracík 21f9329d5d esp32/modnetwork: Fix wifi.isconnected to return False after disconnect.
esp_wifi_connect will return ESP_OK for the normal path of execution which
just means the reconnect is started, not that it is actually reconnected.
In such a case wifi.isconnected() should return False until the
reconnection is complete.  After reconnect a GOT_IP event is called and it
will change wifi_sta_connected back to True.

Glenn Ruben Bakke 0c6f5bc529 nrf/bluetooth: Improve advertisment behavior for nrf52 targets.
This patch makes sure that advertisment data is located in
persistent static RAM memory throughout the advertisment.

Also, setting m_adv_handle to predifined
BLE_GAP_ADV_SET_HANDLE_NOT_SET value to indicate first time
usage of the handle. Upon first advertisment configuration

Andrew Leech 8ed4a28dae stm32/sdram: Increase GPIO speed for SDRAM interface to "very high".
Currently all usages of mp_hal_pin_config_alt_static() set the pin speed to
"high" (50Mhz).  The SDRAM interface typically runs much faster than this
so should be set to the maximum pin speed.

This commit adds mp_hal_pin_config_alt_static_speed() which allows setting
the pin speed along with the other alternate function details.

Dave Hylands 92fec603d0 stm32/make-stmconst.py: Improve regex to parse more constants.
A few RTC constants weren't being parsed properly due to whitespace
differences, and this patch makes certain whitespace optional.  Changes
made:

- allow for no space between /*!< and EXTI, eg for:
  __IO uint32_t IMR; /*!<EXTI Interrupt mask register, Address offset: 0x00 */

- allow for no space between semicolon and start of comment, eg for:

Mike Causer 812969d615 all: Change PYB message prefix to MPY.
Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between
ports, which is a general goal.  And this change won't break pyboard.py
because that tool only looks for "soft reboot".

- microbit, Cortex-M0 via nRF51822
- netduino2, Cortex-M3 via STM32F205
- mps2-an385, Cortex-M3 via FPGA

netduino2 is the default board because it's supported by older qemu
versions (down to at least 2.5.0).

Damien George 1bcf4afb10 stm32/systick: Make periodic systick callbacks use a cyclic func table.
Instead of checking each callback (currently storage and dma) explicitly
for each SysTick IRQ, use a simple circular function table indexed by the
lower bits of the millisecond tick counter.  This allows callbacks to be
easily enabled/disabled at runtime, and scales well to a large number of
callbacks.

Damien George 1669e049de stm32/boards/STM32F769DISC: Configure for use with mboot by default.
This is a good board to demonstrate the use of Mboot because it only has a

Ayke van Laethem 1ba962ff57 nrf/uart: Remove unused machine.UART() parameters.
If needed these parameters can be added back and made functional one at a

Paul Sokolovsky 2f5d113fad py/warning: Support categories for warnings.
Python defines warnings as belonging to categories, where category is a
warning type (descending from exception type). This is useful, as e.g.
allows to disable warnings selectively and provide user-defined warning
types.  So, implement this in MicroPython, except that categories are
represented just with strings.  However, enough hooks are left to implement
categories differently per-port (e.g. as types), without need to patch each
and every usage.

Damien George 86f06d6a87 stm32/sdcard: Don't use SD clock bypass on F7 MCUs.
With clock bypass enabled the attached SD card is clocked at the maximum
48MHz.  But some SD cards are unreliable at these rates.  Although it's
nice to have high speed transfers it's more important that the transfers
are reliable for all cards.  So disable this clock bypass option.

Damien George 38022ddb2c stm32/main: Make board-defined UART REPL use a static object and buffer.
This way the UART REPL does not need the MicroPython heap and exists

Damien George f431795caf esp32/boards: Use auto xtal freq config instead of default 40MHz.
Auto-detection of the crystal frequency is convenient and allows for a
single binary for many different boards.  But it can be unreliable in
certain situations so in production, for a given board, it's recommended to
configure the correct fixed frequency.

Damien George 3d49b157b8 esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure.
Configuration for the build is now specified using sdkconfig rather than
sdkconfig.h, which allows for much easier configuration with defaults from
the ESP IDF automatically applied.  sdkconfig.h is generated using the new
ESP IDF kconfig_new tool written in Python.  Custom configuration for a
particular ESP32 board can be specified via the make variable SDKCONFIG.

The esp32.common.ld file is also now generated using the standard ESP IDF
ldgen.py tool.

Damien George f59904f799 esp32/Makefile: Put all IDF compenents in .a libs to use IDF ld script.
When the ESP IDF builds a project it puts all separate components into
separate .a library archives.  And then the esp32.common.ld linker script
references these .a libraries by explicit name to put certain object files
in iRAM.

This patch does a similar thing for the custom build system used here,
putting all IDF .o's into their respective .a.  So a custom linker script
is no longer needed.
2019-01-28 12:41:37 +11:00
Damien George e7ab475276 esp32: Don't put py/scheduler.o in iRAM, it's no longer needed.
ISR's no longer need to be in iRAM, and the ESP IDF provides an option to
specify that they are in iRAM if an application needs lower latency when
handling them.  But we don't use this feature for user interrupts: both
timer and gpio ISR routines are registered without the ESP_INTR_FLAG_IRAM
option, and so the scheduling code no longer needs to be in iRAM.

Damien George 4caf5b2358 stm32/usbdev: Add USB config option for max power drawn by the board.
The new compile-time option is MICROPY_HW_USB_MAX_POWER_MA.  Set this in
the board configuration file to the maximum current in mA that the board
will draw over USB.  The default is 500mA.
2019-01-27 14:02:10 +11:00
Damien George 7d8db42d17 stm32/usbdev: Add USB config option for board being self powered.
The new compile-time option is MICROPY_HW_USB_SELF_POWERED.  Set this
option to 1 in the board configuration file to indicate that the USB device
is self powered.  This option is disabled by default (previous behaviour).
2019-01-27 13:52:43 +11:00
Damien George c2886868b9 stm32/rtc: Check RTCEN=1 when testing if RTC is already running on boot.
It can be that LSEON and LSERDY are set yet the RTC is not enabled (this
can happen for example when coming out of the ST DFU mode on an F405 with
the RTC not previously initialised).  In such a case the RTC is never
started because the code thinks it's already running.  This patch fixes
this case by always checking if RTCEN is set when booting up (and also
testing for a valid RTCSEL value in the case of using an LSE).

Mikhail Zakharov 18723e9889 unix/mpthreadport: Remove busy wait loop in thread garbage collection.
One can't use pthread calls in a signal handler because they are not
async-signal-safe (see man signal-safety).  Instead, sem_post can be used
to post from within a signal handler and this should be more efficient than
using a busy wait loop, waiting on a volatile variable.

Damien George da72bb6833 esp32/machine_hw_spi: Make HW SPI objects statically allocated.
This aligns more closely with the hardware, that there are two, fixed HW
SPI peripherals.  And it allows to recreate the HW SPI objects without
error, as well as create them again after a soft reset.

Fixes issue #4103.

Matt Trentini cd52d2c691 esp32/modules/neopixel.py: Change NeoPixel to different default timings.
In order to suit the more common 800KHz by default (instead of 400KHz), and

Resolves #4396.

Note! This is a breaking change. Anyone that has previously used the
NeoPixel class on an ESP32 board may be affected.

Damien George 18d3a5df26 esp8266/esp_mphal: Provide mp_hal_pin_od_high_dht so DHT works reliably.
The original behaviour of open-drain-high was to use the open-drain mode of
the GPIO pin, and this seems to make driving a DHT more reliable.  See
issue #4233.
2019-01-22 00:26:04 +11:00
Damien George eb446ec227 esp32/Makefile: Use system provided math library rather than uPy one.
The ESP IDF system already provides a math library, and that one is likely
to be better tuned to the Xtensa architecture.  The IDF components are also
tested against its own math library, so best not to override it.  Using the
system provided library also allows to easily switch to double-precision
floating point by changing MICROPY_FLOAT_IMPL to MICROPY_FLOAT_IMPL_DOUBLE.

Damien George 36808d4e6a esp8266/main: Activate UART(0) on dupterm for REPL before boot.py runs.
So that the user can explicitly deactivate UART(0) if needed.  See
issue #4314.

This introduces some risk to "brick" the device, if the user disables the
REPL without providing an alternative REPL (eg WebREPL), or any way to
reenable it.  In such a case the device needs to be erased and
reprogrammed.  This seems unavoidable, given the desire to have the option
to use the UART for something other than the REPL.

Damien George 3431ea7205 stm32/main: Make thread and FS state static and exclude when not needed.
Without the static qualifier these objects will be kept by the linker even

unused by a board.

Damien George f350b640a0 esp32/modsocket: For socket read only release GIL if socket would block.
If there are many short reads to a socket in a row (eg by readline) then
releasing and acquiring the GIL each time will give very poor throughput.
So first poll the socket to see if it has data, and if it does then don't
release the GIL.
2019-01-10 15:46:44 +11:00
Damien George efe0569c26 esp32/mphalport: When tx'ing to REPL only release GIL if many chars sent
Otherwise, if multiple threads are active, printing data to the REPL may be

Damien George 7bdbea9a0c stm32/uart: Clear overrun error flag after reading RX data register.
On MCUs other than F4 the ORE (overrun error) flag needs to be cleared
independently of clearing RXNE, even though both are wired to trigger the
same RXNE IRQ.  In the case that an overrun occurred it's necessary to
explicitly clear the ORE flag or else the RXNE interrupt will keep firing.
2018-12-30 00:59:16 +11:00
Damien George 0d860fdcd0 stm32/uart: Always enable global UART IRQ handler on init.
Otherwise IRQs may not be enabled for the user UART.irq() handler.  In

Andrew Leech ce0c581179 stm32/main: Add board config option to enable/disable mounting SD card.
The new option MICROPY_HW_SDCARD_MOUNT_AT_BOOT can now be defined to 0 in
mpconfigboard.h to allow SD hardware to be enabled but not auto-mounted at
boot.  This feature is enabled by default to retain previous behaviour.

Previously, if an SD card is enabled in hardware it is also used to boot
from.  While this can be disabled with a SKIPSD file on internal flash,
this wont be available at first boot or if the internal flash gets
corrupted.

Damien George 485514f57a esp32: Allocate task TCB and stack from system heap not uPy heap.
This is necessary for two reasons: 1) FreeRTOS still needs the TCB data
structure even after vPortCleanUpTCB has been called, so this latter hook
function cannot free the TCB, and there is no where else to safely delete
it (this behaviour has changed recently in the ESP IDF); 2) when using
external SPI RAM the uPy heap is in this external memory but the task stack
must be allocated from internal SRAM.

Paul Sokolovsky 0c18633ea9 unix/modusocket: Finish socket.settimeout() implementation.
1. Return correct error code for non-blocking vs timed out socket
(POSIX returns EAGAIN for both, we want ETIMEDOUT in case of timed
out socket). To achieve this, blocking/non-blocking flag is added
to the mp_obj_socket_t, to avoid issuing fcntl() syscall each time
EAGAIN occurs. (mp_obj_socket_t used to be 8 bytes, having some room
in a standard 16-byte alloc block.)

2. Handle socket.settimeout(0) properly - in Python, that means
non-blocking mode, but SO_RCVTIMEO/SO_SNDTIMEO of 0 is infinite
timeout.

3. Overall, make sure that socket.settimeout() call switches blocking
state as expected.

Damien George 0f6f86ca49 stm32/usbd_cdc_interface: Refactor USB CDC tx code to not use SOF IRQ.
Prior to this commit the USB CDC used the USB start-of-frame (SOF) IRQ to
regularly check if buffered data needed to be sent out to the USB host.
This wasted resources (CPU, power) if no data needed to be sent.

This commit changes how the USB CDC transmits buffered data:
- When new data is first available to send the data is queued immediately
  on the USB IN endpoint, ready to be sent as soon as possible.
- Subsequent additions to the buffer (via usbd_cdc_try_tx()) will wait.
- When the low-level USB driver has finished sending out the data queued
  in the USB IN endpoint it calls usbd_cdc_tx_ready() which immediately
  queues any outstanding data, waiting for the next IN frame.

The benefits on this new approach are:
- SOF IRQ does not need to run continuously so device has a better chance
  to sleep for longer, and be more responsive to other IRQs.
- Because SOF IRQ is off, current consumption is reduced by a small amount,
  roughly 200uA when USB is connected (measured on PYBv1.0).
- CDC tx throughput (USB IN) on PYBv1.0 is about 2.3 faster (USB OUT is
  unchanged).
- When USB is connected, Python code that is executing is slightly faster
  because SOF IRQ no longer interrupts continuously.
- On F733 with USB HS, CDC tx throughput is about the same as prior to this
  commit.
- On F733 with USB HS, Python code is about 5% faster because of no SOF.

As part of this refactor, the serial port should no longer echo initial
characters when the serial port is first opened (this only used to happen
rarely on USB FS, but on USB HS is was more evident).

Glenn Ruben Bakke 11bc38d55f nrf/bluetooth: Set GAP_ADV_MAX_SIZE to 31 (s132/s140).
For s132 and s140, GAP_ADV_MAX_SIZE was currently set to
BLE_GATT_ATT_MTU_DEFAULT, which is 23. The correct value
should have been 31, but there are no define for this in
the s132/s140 header files as for s110.

Updating define in ble_drv.c to the correct value of 31.

Andrew Leech 338635ccc6 stm32/main: Add configuration macros for board to set heap start/end.
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).

As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot.  On boards with SDRAM enabled the heap
has been set to use that.

Damien George 84090edaa3 stm32/mpconfigport.h: Enable math.factorial, optimised version. 2018-09-26 15:05:19 +10:00
Christopher Swenson 8c656754aa py/modmath: Add math.factorial, optimised and non-opt implementations.
This commit adds the math.factorial function in two variants:
- squared difference, which is faster than the naive version, relatively
  compact, and non-recursive;
- a mildly optimised recursive version, faster than the above one.

There are some more optimisations that could be done, but they tend to take
more code, and more storage space.  The recursive version seems like a
sensible compromise.

The new function is disabled by default, and uses the non-optimised version
by default if it is enabled.  The options are MICROPY_PY_MATH_FACTORIAL
and MICROPY_OPT_MATH_FACTORIAL.

Damien George 9fb1f18cf4 stm32/sdcard: Fully reset SDMMC periph before calling HAL DMA functions.
The HAL DMA functions enable SDMMC interrupts before fully resetting the
peripheral, and this can lead to a DTIMEOUT IRQ during the initialisation
of the DMA transfer, which then clears out the DMA state and leads to the
read/write not working at all.  The DTIMEOUT is there from previous SDMMC
DMA transfers, even those that succeeded, and is of duration ~180 seconds,
which is 0xffffffff / 24MHz (default DTIMER value, and clock of
peripheral).

To work around this issue, fully reset the SDMMC peripheral before calling
the HAL SD DMA functions.

Fixes issue #4110.

Damien George 6b3d6da74b stm32/flashbdev: Protect flash writes from cache flushing and USB MSC. 2018-09-12 15:58:42 +10:00
Damien George 0941a467e7 stm32: Change flash IRQ priority from 2 to 6 to prevent preemption.
The flash-IRQ handler is used to flush the storage cache, ie write
outstanding block data from RAM to flash.  This is triggered by a timeout,
or by a direct call to flush all storage caches.

Prior to this commit, a timeout could trigger the cache flushing to occur
during the execution of a read/write to external SPI flash storage.  In
such a case the storage subsystem would break down.

SPI storage transfers are already protected against USB IRQs, so by
changing the priority of the flash IRQ to that of the USB IRQ (what is
done in this commit) the SPI transfers can be protected against any
timeouts triggering a cache flush (the cache flush would be postponed until
after the transfer finished, but note that in the case of SPI writes the
timeout is rescheduled after the transfer finishes).

The handling of internal flash sync'ing needs to be changed to directly
call flash_bdev_irq_handler() sync may be called with the IRQ priority
already raised (eg when called from a USB MSC IRQ handler).

Damien George 47550ef2cd stm32: For MCUs that have PLLSAI allow to set SYSCLK at 2MHz increments.
MCUs that have a PLLSAI can use it to generate a 48MHz clock for USB, SDIO
and RNG peripherals.  In such cases the SYSCLK is not restricted to values
that allow the system PLL to generate 48MHz, but can be any frequency.
This patch allows such configurability for F7 MCUs, allowing the SYSCLK to
be set in 2MHz increments via machine.freq().  PLLSAI will only be enabled
if needed, and consumes about 1mA extra.  This fine grained control of
frequency is useful to get accurate SPI baudrates, for example.

makes this macro a pointer rather than the actual mp_print_t struct.  This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.

Ports are updated to use the new macro name.

Stig Bjørlykke 0c161691b4 nrf: Correct index checking of ADC/PWM/RTCounter instances.
Avoid trying to use ADC, PWM and RTCounter instances which is
one past last available, because this will give a HardFault.

Stig Bjørlykke 7f0c5f2ef9 nrf: Enable all PWM, RTC and Timer instances for nrf52840.
The NRF52 define only covers nrf52832, so update the define checks
to use NRF52_SERIES to cover both nrf52832 and nrf52840.

Fixed machine_hard_pwm_instances table in modules/machine/pwm.c

This enables PWM(0) to PWM(3), RTCounter(2), Timer(3) and Timer(4),
in addition to NFC reset cause, on nrf52840.

Damien George 5482d84673 stm32/modmachine: Get machine.sleep working on L4 MCUs.
When waking from stop mode most of the system is still in the same state as
before entering stop, so only minimal configuration is needed to bring the
system clock back online.

Damien George 9dfbb6cc16 stm32/rtc: Get rtc.wakeup working on F0 MCUs.
The problem was that the EXTI line for the RTC wakeup event is line 20 on
the F0, so the interrupt was not firing.

Damien George f6f6452b6f stm32/Makefile: Use -Wno-attributes for ll_usb.c HAL source file.
A recent version of arm-none-eabi-gcc (8.2.0) will warn about unused packed
attributes in USB_WritePacket and USB_ReadPacket.  This patch suppresses
such warnings for this file only.

Damien George 4201f36a46 stm32/sdcard: Use mp_hal_pin_config_alt_static to configure SD card pins 2018-07-20 14:03:21 +10:00
Andrew Leech 4343c9330e stm32: Add method for statically configuring pin alternate function.
Works with pins declared normally in mpconfigboard.h, eg. (pin_XX), as well
as (pyb_pin_XX).

Provides new mp_hal_pin_config_alt_static(pin_obj, mode, pull, fn_type)
function declared in pin_static_af.h to allow configuring pin alternate
functions by name at compile time.

Damien George ef554ef9a2 unix: Use MP_STREAM_GET_FILENO to allow uselect to poll general objects.
This mechanism will scale to to an arbitrary number of pollable objects, so
long as they implement the MP_STREAM_GET_FILENO ioctl.  Since ussl objects
pass through ioctl requests transparently to the underlying socket object,
it will allow ussl sockets to be polled.  And a user object with uio.IOBase
as a base could support polling.

Peter D. Gray a8736e5c36 stm32/flashbdev: Fix bug with L4 block cache, dereferencing block size.
The code was dereferencing 0x800 and loading a value from there, trying to
use a literal value (not address) defined in the linker script
(_ram_fs_cache_block_size) which was 0x800.
