Damien George dd7d2e0810 stmhal: Only use BASEPRI irq stuff if Cortex is M3 or higher. 2015-12-04 12:13:12 +00:00
Damien George f7697ff393 stmhal: Add rtc.init() method to force RTC to re-initialise. 2015-12-04 12:05:05 +00:00
Damien George f4c17378b3 stmhal: Protect SD card DMA transactions against USB MSC contention.
Consider the following scenario: SD card is being read by pyboard; USB
irq comes in for MSC read request; SD card needs to be read from within
USB irq while SD read is already ongoing.  Such contention needs to be
avoided.

This patch provides a simple solution, to raise the irq priority above
that of the USB irq during SD DMA transfers.  Pyboard and PC can now
read from the SD card at the same time (well, reads are interleaved).

Damien George 95c9cc8114 stmhal: Add raise_irq_pri and restore_irq_pri functions.
These can be used to disable only certain interrupts, ones at or above
the given priority value.

Damien George 0d9b450701 stmhal: Make uart.write() function correctly for timeout=0.
In non-blocking mode (timeout=0), uart.write() can now transmit all of its
data without raising an exception.  uart.read() also works correctly in
this mode.

As part of this patch, timout_char now has a minimum value which is long
enough to transfer 1 character.

Addresses issue #1533.

Ryan Shaw f99491cbf7 stmhal: uart.any() function now returns number of bytes available. 2015-11-30 13:07:20 +00:00
Dave Hylands 3048433809 stmhal: Make stm.mem* support large integers.
With these you can now do things like:

stm.mem32[0x20000000] = 0x80000000

and read 32-bit values. You can also read all the way to the end
of memory using either stm.mem32[0xfffffffc] or stm.mem32[-4].

IRQs shouldn't use mem32 at all since they'd fail if the top 2 bits
weren't equal, so IRQs should be using 16-bit I/O.

Dave Hylands 061eb6fa6b stmahl: Fix usbd_conf.c for devices which don't have USB_HS at all.
The STMCube examples define both USE_USB_HS and USE_USB_HS_IN_FS when they
use the HS in FS mode.

The STM32F401 doesn't have a USB_HS at all, so the USB_OTG_HS instance
doesn't even exist.

Dave Hylands c8437f97ae stmhal: Increase the priority of UART IRQ.
The UARTs have no FIFOs, so if interrupts are disabled
for more than a character time (10 usec at 1 Mbit/sec)
then characters get dropped.

The overhead for handling a UART ISR is about 0.5 usec,
so even at baud rates of 1 Mbit/sec this only corresponds
to about 5% of the CPU. Lower baud rates will have less
of an impact.

Damien George 36bd10779c stmhal: In SysTick IRQ handler, make uwTick variable non-volatile.
uwTick can only change in the SysTick IRQ so this IRQ function does not
need to take special care with this variable.  It's important to make
this IRQ function as efficient as possible.

Damien George e99e6c883d stmhal: Move flash storage idle tick handler from TIM3 to SysTick.
Using SysTick to do the counting and dispatch of the flash storage idle
handler is more efficient than requiring a dedicated hardware timer.
No new counter is needed, just the existing uwTick variable.  The
processing is not actually done in the SysTick IRQ, it is deferred to
the flash IRQ (which runs at lower priority).

Dave Hylands b677f03407 stmhal: Turn off DMA clocks when idle for 100 msec
Turning on each DMA block increases the current consumption
by about 8 mA. This code adds an idle timer for each DMA
block and turns off the clocks when no streams are in use
for 128 msec. Having a small timeout allows for improved
performance when back-to-back transfers are being performed.

The 128 msec is basically a guess.

  for sdcard I/O when using USB Mass Storage.

T S 86aa16bea6 stmhal: Implement delayed RTC initialization with LSI fallback.
If RTC is already running at boot then it's left alone.  Otherwise, RTC is
started at boot but startup function returns straight away.  RTC startup
is then finished the first time it is used.  Fallback to LSI if LSE fails
to start in a certain time.

Also included:
 MICROPY_HW_CLK_LAST_FREQ
        hold pyb.freq() parameters in RTC backup reg
 MICROPY_HW_RTC_USE_US
        option to present datetime sub-seconds in microseconds
 MICROPY_HW_RTC_USE_CALOUT
        option to enable RTC calibration output

CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

Paul Sokolovsky 16d42368a6 stmhal/modmachine: Initial attempt to add I2C & SPI classes.
In new hardware API, these classes implement master modes of interfaces,
and "mode" parameter is not accepted. Trying to implement new HW API
in terms of older pyb module leaves variuos corner cases:

In new HW API, I2C(1) means "I2C #1 in master mode" (? depends on
interpretation), while in old API, it means "I2C #1, with no settings
changes".

For I2C class, it's easy to make mode optional, because that's last
positional param, but for SPI, there's "baudrate" after it (which
is inconsistent with I2C, which requires "baudrate" to be kwonly-arg).

Paul Sokolovsky 0dbd928cee Makefiles: Remove duplicate object files when linking.
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

Paul Sokolovsky bedab235f9 stmhal/uart: If char is not received within timeout, return EAGAIN error.
Instead of return 0, which means EOF. There's no good way to detect EOF on
continuously active bus like UART, and treat timeout as just temporary
unvailability of data. .read() method of UART object will return None in
this case (instead of 0, which again measn EOF). This is fully compliant
with unix port.

Damien George b5c43be135 stmhal: Allow to set bits resolution for DAC; 8 is default, can have 12.
This patch allows to configure the DAC resolution in the constructor and
in the init function, eg:

dac = DAC(1, bits=12).

The default resolution is 8 bits for backwards compatibility.  The bits
sets the maximum value accepted by write and write_timed methods, being
2**bits - 1.

When using write_timed with 12-bit resolution, the input buffer is
treated as an unsigned half-word array, typecode 'H'.

Dave Hylands 01d64914c5 stmhal: Fix USB CDC-only mode under Windows.
This fix adds PIDs 9801 and 9802 to the pybcdc.inf file.

When in CDC only mode, it presents itself as a Communcations
device rather than as a composite device. Presenting as a
composite device with only the CDC interface seems to confuse
windows.

To test and make sure that the correct pybcdc.inf was being used,
I used USBDeview from http://www.nirsoft.net/utils/usb_devices_view.html
to uninstall any old pyboard drivers (Use Control-F and search
for pyboard). I found running USBDeview as administrator worked best.

Installing the driver in CDC+MSC mode first is recommended (since the
pybcdc.inf file in on the internal flash drive). Then when you switch
modes everything seems to work properly.

I used https://github.com/dhylands/upy-examples/blob/master/boot_switch.py
to easily switch the pyboard between the various USB modes for testing.

Damien George d80174d7c3 stmhal: Use polling, not DMA, for 1 byte SPI transfers.
There is an issue sending 1 byte on the SPI bus using DMA, but it only
occurs when the transmit is done for the first time after initialising
the SPI and DMA peripherals.  All other cases (sending 2 or more bytes,
doing send_recv, doing recv first) work okay.  We sidestep this issue by
using polling (not DMA) for all 1 byte transfers.  This is fine because
a 1 byte transfer can't be interrupted and doesn't need the benefits of
DMA (and using polling for this case is more efficient).

Resolves #1456.

Dave Hylands 8f1eced69d stmhal: Add STM32F7 support for USB serial and storage.
USB serial is now working for F7.

Internal file storage is now working for F7.  The flash is laid out a bit
differently to the F4 - 4 x 32K, 1 x 128K with the rest 256K, so the
internal storage is 96K.

Added more pind definitions for STM32F7DISC board.  Made USART1 be the
default HWUART repl.  The STLINK usb connector also looks like a USB
serial port which is attached to USART1 on the STM32F7DISC.
2015-08-03 00:39:27 +01:00
Damien George 751485fe6b stmhal: Add support for USART1 and conditional pins in make-pins.py.

2015-07-27 23:52:56 +01:00
Damien George 92e9a5e0a7 stmhal: Check if user block device is mounted before accessing it.
In particular this fixes a bug where pyb.sync (and os.sync) fail because
they try to sync the user mounted device even if it's not mounted.
2015-07-27 23:40:19 +01:00
Tom Soulanille 7d588b0c7c lib/mp-readline: Add emacs-style control characters for cursor movement.

2015-07-26 15:22:13 +01:00
Damien George 7693ef3bd6 stmhal: Allow ADC.read_timed to take Timer object in place of freq.
This allows a user-specified Timer for the triggering of the ADC read,
mirroring the new behaviour of DAC.write_timed.

Addresses issue #1129.
2015-07-22 19:41:13 +01:00
Damien George 99a21dc05d stmhal: Add stm32fxxx_hal_i2s_ex.c to hal/f2 (dummy) and hal/f4. 2015-07-21 23:49:19 +01:00
Damien George abc24c1876 stmhal: Allow DAC.write_timed to take Timer object in place of freq.
This allows the DAC to use a user-specified Timer for the triggering
(instead of the default Timer(6)), while still supporting original
behaviour.

Addresses issues #1129 and #1388.
2015-07-21 23:39:49 +01:00

Damien George e4d43401eb stmhal: Move HAL Cube files to f4/ subdir, keeping only those we use.
This is in preparation for supporting other MCU series, such as
STM32F2xx.  Directory structure for the HAL is now hal/f4/{inc,src},
where "f4" will in the future be different for other series.

HAL source/header files that are not use are removed to reduce the size
of the code.

Damien George 0807139c1d stmhal: Add config option for storage to use second flash segment.
When enabled this allows the internal storage to be split over 2
contiguous regions of flash (two segments), and so the storage can be
increased.

This option is disabled by default, giving original behaviour.
2015-06-27 23:27:23 +01:00
blmorris c5175526dd stmhal/dma.c: Modify dma_init() to accept init struct as an argument
This removes hard-coded DMA init params from dma_init(), instead defining
these parameters in a DMA_InitTypeDef struct that gets passed as an
argument to dma_init()
This makes dma_init more generic so it can be used for I2S and SD Card,
which require different initialization parameters.
2015-06-24 17:48:52 +01:00

2015-06-10 14:01:44 +01:00
Damien George 0aa5e75000 stmhal: Break immediately from USB CDC busy wait loop if IRQs disabled.
If IRQs are disabled then the USB CDC buffer will never be
drained/filled and the sys-tick timer will never increase, so we should
not busy wait in this case.

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Damien George b1f68685ec stmhal: In USB HID driver, make polling interval configurable.
When setting usb_mode to "HID", hid config object now has
polling-interval (in ms) as the 4th element.  It mmust now be a 5-tuple
of the form:

(subclass, protocol, max_packet_len, polling_interval, report_desc)

The mouse and keyboard defaults have polling interval at 8ms.

Daniel Campora 7b19e99edd lib: Update FatFs to R0.11.
There are lots of cosmetic changes, but this release brings a  very
important bug fix:
 - Fixed f_unlink() does not remove cluster chain of the file.

With R0.10c if you try to write a file that is too large to fit in the
free space of the drive, the operation fails, you delete the incomplete
file, and it seems to be erased, but the space is not really freed,
because any subsequent write operations fail because the drive is
"still" full. The only way to recover from this is by formatting the
drive. I can confirm that R0.11 fixes the problem.

Paul Sokolovsky 0ef01d0a75 py: Implement core of OrderedDict type.
Given that there's already support for "fixed table" maps, which are
essentially ordered maps, the implementation of OrderedDict just extends
"fixed table" maps by adding an "is ordered" flag and add/remove
operations, and reuses 95% of objdict code, just making methods tolerant
to both dict and OrderedDict.

Some things are missing so far, like CPython-compatible repr and comparison.

OrderedDict is Disabled by default; enabled on unix and stmhal ports.

Damien George 5cbeacebdb py: Make math special functions configurable and disabled by default.
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

Damien George 65af7ebdc5 stmhal: Put CDC last in config descriptors to match with iface nums.
Apparently the order of interface numbers should be sequential and
increasing in a config descriptor.  So as to retain compatibility with
Windows drivers for the CDC+MSC and CDC+HID modes, we move the CDC
configs to the end of the descriptors, instead of changing the interface
numbers.

See PR #957 for background.

Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

blmorris 97f14606f5 stmhal/adc.c: Fix calculation of read_core_vref()
There was a stray factor of 2 (VBAT_DIV) that looks like it was copied incorrectly from the read_core_vbat() function.
The factor exists in read_core_vbat() because VBAT is measured through a 2:1 voltage divider.
read_core_vref now returns values around 1.21V (assuming that external reference voltage is 3.3V) which is in line with the datasheet values.

Damien George 827b0f747b py: Change vstr_null_terminate -> vstr_null_terminated_str, returns str. 2015-01-29 13:57:23 +00:00
Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
This cleans up vstr so that it's a pure "variable buffer", and the user
can decide whether they need to add a terminating null byte.  In most
places where vstr is used, the vstr did not need to be null terminated
and so this patch saves code size, a tiny bit of RAM, and makes vstr
usage more efficient.  When null termination is needed it must be
done explicitly using vstr_null_terminate.

Damien George ad33e2465c stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
It uses RAM and on pyboard we are generally tight on RAM, so disable
this optimisation for general builds.  If users need the speed then
they can build their own version.  Maybe in the future we can have
different versions of pyboard firmware built with different tradeoffs.

Damien George 23342c09ff stmhal: Bug fix for usocket's accept and setsockopt methods.
accept might raise an exception, in which case the new socket is not
fully created.  It has a finaliser so will run close() method when GC'd.
Before this patch close would try to close an invalid socket.  Now
fixed.

setsockopt took address of stack value which became out of scope.  Now
fixed.

Damien George 05005f679e py: Remove mp_obj_str_builder and use vstr instead.
With this patch str/bytes construction is streamlined.  Always use a
vstr to build a str/bytes object.  If the size is known beforehand then
use vstr_init_len to allocate only required memory.  Otherwise use
vstr_init and the vstr will grow as needed.  Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.

Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.

Paul Sokolovsky 87bc8e2b3d pyexec: Add event-driven variant pyexec_friendly_repl().
pyexec_friendly_repl_process_char() and friends, useful for ports which
integrate into existing cooperative multitasking system.

Unlike readline() refactor before, this was implemented in less formal,
trial&error process, minor functionality regressions are still known
(like soft&hard reset support). So, original loop-based pyexec_friendly_repl()
is left intact, specific implementation selectable by config setting.

Damien George 131185a2b8 stmhal: Add MICROPY_HW_USB_OTG_ID_PIN config, set for relevant boards.
This config option is for the USB OTG pin, pin A10.  This is used on
some boards but not others.  Eg PYBv3 uses PA10 for LED(2), so it
shouldn't be used for OTG ID (actually PA10 is multiplexed on this
board, but defaults to LED(2)).

Partially addresses issue #1059.

qstr_info but not mem_{total,current,peak}.

just the fact that it is defined.

Damien George 7ee91cf861 py: Add option to cache map lookup results in bytecode.
This is a simple optimisation inspired by JITing technology: we cache in
the bytecode (using 1 byte) the offset of the last successful lookup in
a map. This allows us next time round to check in that location in the
hash table (mp_map_t) for the desired entry, and if it's there use that
entry straight away.  Otherwise fallback to a normal map lookup.

Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.

On a few tests it gives >90% cache hit and greatly improves speed of
code.

Disabled by default.  Enabled for unix and stmhal ports.

Damien George b4b10fd350 py: Put all global state together in state structures.
