Damien George ed559de063 stmhal/led: Use mp_hal_pin_config function instead of HAL_GPIO_Init. 2016-12-22 14:55:26 +11:00
Damien George ffa30898cc stmhal/usrsw: Use mp_hal_pin_config function instead of HAL_GPIO_Init. 2016-12-22 14:55:26 +11:00
Damien George 425150040c stmhal/mphalport.h: Explicitly use HAL's GPIO constants for pull modes.
They are the same as the existing raw constants (namely 0, 1, 2) but we
want to explicitly show that one can use the HAL's constants if necessary
(eg the mpconfigboard.h files do use the HAL's constants to define the
pull state of certain configurable pins).

Damien George b14abab9cd stmhal/led: Properly initialise timer handle to zero before using it.
Without this the timer will have random values for its State and Lock
entries.  The object can then be in a locked state leading to some HAL
functions returning immediately with an error code (which is unchecked).

This patch fixes such a bug which did manifest itself as PWM not working
correctly for LEDs.

Damien George a770ba147e stmhal: Use core-provided keyboard exception object. 2016-12-15 15:51:34 +11:00
Damien George 979ab4e126 stmhal/usb: Always use the mp_kbd_exception object for VCP interrupt.
There's no need to store a separate pointer to this object.
2016-12-15 12:45:56 +11:00
Damien George f254cfd3c4 stmhal: Rename mp_const_vcp_interrupt to mp_kbd_exception.
mp_kbd_exception is now considered the standard variable name to hold the
singleton KeyboardInterrupt exception.

This patch also moves the creation of this object from pyb_usb_init() to
main().

Damien George 1b02565316 stmhal/mpconfigport: Add weak-module links for io, collections, random. 2016-12-15 11:23:20 +11:00
Damien George e8f2db7da3 py/runtime: Zero out fs_user_mount array in mp_init.
There's no need to force ports to copy-and-paste this initialisation
code.  If FSUSERMOUNT is enabled then this zeroing out must be done.
2016-12-14 11:40:11 +11:00
Damien George 0f408bc1ff stmhal: Move PY_SYS_PLATFORM config from board to general config file.
It can be overridden by a board if needed.
2016-12-13 16:26:45 +11:00
Rami Ali 8001918a89 stmhal: Add STM32F769DISC board files.
With minor changes to adc.c and storage.c to support the F769.
2016-12-13 16:26:13 +11:00
Rami Ali 3dd04dee3e stmhal/cmsis: Add CMSIS file stm32f769xx.h, V1.1.2. 2016-12-13 16:25:56 +11:00
Rami Ali e9fbc555fc stmhal: Add NUCLEO_F767ZI board, with openocd config for stm32f7. 2016-12-13 16:25:31 +11:00
Rami Ali 517f347f6f stmhal/cmsis: Add CMSIS file stm32f767xx.h, V1.1.2. 2016-12-13 16:24:24 +11:00
Damien George 1b6d94bccd stmhal: Refactor to use extmod implementation of software SPI class.
This is a pure refactoring (and simplification) of code so that stmhal
uses the software SPI class provided in extmod, for the machine.SPI
implementation.
2016-12-08 13:58:10 +11:00
Damien George 1eb3c66e91 extmod/machine_spi: Provide reusable software SPI class.
So long as a port defines relevant mp_hal_pin_xxx functions (and delay) it
can make use of this software SPI class without the need for additional
code.
2016-12-08 13:47:01 +11:00
Damien George d9c839742f stmhal/hal: Update HALCOMMITS due to change in f7 hal files. 2016-12-07 17:36:42 +11:00
Rami Ali db5a4e8f3c stmhal/boards/STM32F7DISC: Define LSE_STARTUP_TIMEOUT.
So it compiles with the latest F7 hal.
2016-12-07 17:31:21 +11:00
Rami Ali 6901649f54 stmhal: Declare and initialise PrescTables for F7 MCUs. 2016-12-07 17:31:09 +11:00
Rami Ali 44cb2ff7ab stmhal: Port of f4 hal commit 1d7fb82 to updated f7 hal. 2016-12-07 17:31:07 +11:00
Rami Ali 821863751f stmhal: Port of f4 hal commit 09de030 to updated f7 hal. 2016-12-07 17:31:05 +11:00
Rami Ali e1c6ed634f stmhal: Port of f4 hal commit c568a2b to updated f7 hal. 2016-12-07 17:30:44 +11:00
Rami Ali b9741cd8f8 stmhal/hal: Update ST32CubeF7 HAL files to V1.1.2.
These files originate from the STM32Cube_FW_F7_V1.5.0 software package
from ST.  Newlines are unixified and trailing whitespace is removed.
2016-12-07 17:28:33 +11:00
Rami Ali d9677f4098 stmhal/cmsis: Update STM32F7 CMSIS device include files to V1.1.2. 2016-12-07 17:27:40 +11:00
Damien George 4c7d799b82 stmhal/uart: Add check that UART id is valid for the given board.
Previous to this patch trying to construct, but not init, a UART that
didn't exist on the target board would actually succeed.  Only when
initialising the UART would it then raise an exception that the UART does
not exist.

This patch adds an explicit check that the constructed UART does in fact
exist for the given board.
2016-12-05 15:31:16 +11:00
Damien George aaab6a9921 stmhal/uart: Add support for UART7 and UART8 on F7 MCUs. 2016-12-05 15:14:22 +11:00
Rami Ali 27a503f632 stmhal: Refactor UART configuration to use pin objects.
This follows the pattern of other peripherals (I2C, SPI) to specify the
pins using pin objects instead of a pair of GPIO port and pin number.  It
makes it easier to customise the UART pins for a particular board.
2016-12-05 14:26:41 +11:00
Damien George fcd10882bd stmhal/adc: Use constants from new HAL version. 2016-12-05 10:51:00 +11:00
Damien George 2d329c4a56 extmod/moduselect: Use configurable EVENT_POLL_HOOK instead of WFI.
To make moduselect be usable by any port.
2016-12-02 16:40:39 +11:00
Damien George 304cfda8c4 py/stream: Move ad-hoc ioctl constants to stream.h and rename them.
The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.
2016-12-02 16:37:29 +11:00
Damien George f7545b200e stmhal/moduos: Implement POSIX behaviour of rename, allow to overwrite. 2016-12-02 15:13:29 +11:00
Jean-François Milants 08bd7d1d31 stmhal/sdcard: Clean/invalidate cache before DMA transfers with SD card.
Add 2 macros in mphalport.h that clean and invalidate data caches only on
STM32F7 MCUs.  They are needed to ensure the cache coherency before/after
DMA transferts.

* MP_HAL_CLEANINVALIDATE_DCACHE cleans and invalidate the data cache. It
  must be called before starting a DMA transfer from the peripheral to the
  RAM memory.

* MP_HAL_CLEAN_DCACHE cleans the data cache.  It must be called before
  starting a DMA transfert from the RAM memory to the peripheral.

These macros are called in sdcard.c, before reading from and writing to
the SDCard, when DMA is used.
2016-12-02 13:51:09 +11:00
Damien George c19a395cac stmhal/adc: Make channel "16" always map to the temperature sensor.
The temperature sensor on F4 and F7 MCUs is mostly, but not always, on
channel 16.  To retain compatibility across all these MCUs this patch
maps the user-facing channel 16 to the internal temperature sensor.
2016-11-30 12:58:54 +11:00
Damien George 390ce86a30 stmhal/adc: Add support for F767 MCU. 2016-11-30 12:58:54 +11:00
Damien George 52dfad0879 stmhal/adc: Add ADCAll.read_vref method, returning "3.3v" value. 2016-11-30 12:58:54 +11:00
Damien George e72353cc48 stmhal/adc: Make ADCAll.read_core_temp return accurate float value.
It now uses factory calibration values to get a more accurate value, and
returns a float instead of an integer.
2016-11-30 12:58:53 +11:00
Damien George 87215a0f04 stmhal/adc: Provide more accurate measure of VBAT and VREFINT.
By using factory calibration values.
2016-11-30 12:58:53 +11:00
Damien George 029f215ead stmhal/adc: Add "mask" selection parameter to pyb.ADCAll constructor.
The "mask" parameter is used to select which pins the ADCAll constructor
will initialise to analog mode.  It defaults to all pins (0xffffffff),
which is backwards compatible with previous behaviour.
2016-11-29 14:32:05 +11:00
Nicholas Graumann 0d75b0d962 stmhal: Add address parameters to openocd config files.
Also make l4 config the default for STM32L476DISC board.
2016-11-28 15:27:36 +11:00
Nicholas Graumann 50a2966913 stmhal: Add OpenOCD configuration for STM32L4. 2016-11-28 15:27:36 +11:00
Damien George 139b891d6d stmhal: Add back GPIO_BSRRL and GPIO_BSRRH constants to stm module.
These were inadvertently removed with a recent upgrade to CMSIS, where
those registers were no longer defined in the CMSIS headers, and hence
no longer extracted.
2016-11-28 15:02:42 +11:00
Dave Hylands 21e1703d37 stmhal: Add support for flash storage on STM32F415. 2016-11-26 16:47:45 +11:00
Damien George f8b71aabb4 stmhal/machine_i2c: Provide HW implementation of I2C peripherals for F4.
With this patch machine.I2C() uses HW I2C peripheral blocks on F4 MCUs.
Software I2C is used for other MCUs.
2016-11-25 16:31:43 +11:00
Damien George 49dcc253e3 stmhal/i2c: Expose the pyb_i2c_obj_t struct and some relevant functions.
So they can be used by other parts of the code.
2016-11-25 16:30:51 +11:00
Damien George 652ca2017d stmhal/i2c: Add support for I2C4 hardware block on F7 MCUs. 2016-11-25 11:21:18 +11:00
Damien George 3053748987 stmhal: Add beginnings of port-specific machine.I2C implementation.
This allows one to construct an I2C object using ids that are specific
to the stmhal port, eg machine.I2C('X').  Right now the implementation
of I2C uses software I2C but the idea is to just change the C-level I2C
protocol functions to hardware implementations later on.
2016-11-24 00:20:51 +11:00
Damien George a3320e7811 stmhal/i2c: Remove use of legacy I2C_NOSTRETCH_DISABLED option.
In the new HAL this is renamed to I2C_NOSTRETCH_DISABLE.
2016-11-22 17:40:50 +11:00
Damien George 7e820792da stmhal: Updates to get F411 MCUs compiling with latest ST HAL. 2016-11-21 23:24:24 +11:00
Damien George 21d82421cd stmhal/i2c: Use the HAL's I2C IRQ handler for F7 and L4 MCUs.
The custom IRQ handler only works for F4 MCUs, which have the SR1
register.
2016-11-21 16:12:09 +11:00
Paul Sokolovsky 8f5bc3ffc0 stmhal/moduselect: Move to extmod/ for reuse by other ports. 2016-11-21 00:05:56 +03:00
Krzysztof Blazewicz 5e9057210a stmhal: Update HALCOMMITS due to change to hal. 2016-11-16 14:05:37 +01:00
Damien George e01e214259 stmhal/make-stmconst.py: Restore Python 2 compatibility. 2016-11-16 23:53:55 +11:00
Damien George 87f18c08c9 stmhal: Update HALCOMMITS due to change to hal. 2016-11-16 23:43:02 +11:00
Damien George c5621529c9 stmhal/make-stmconst.py: Add support for files with invalid utf8 bytes. 2016-11-16 23:29:02 +11:00
Krzysztof Blazewicz 4d9dce7759 stmhal/mphalport.h: use single GPIOx->BSRR register 2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 13400e1375 stmhal/hal: do not include <stdio.h> in HAL headers
stdio.h was included in all HAL files only to provide
definition of NULL symbol

"stdio.h" includes "types.h" which contains some conflicting definitions
with "drivers/cc3000/inc/socket.h"
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 8fa0733647 stmhal/i2c: provide custom IRQ handlers
Use custom handlers providing minimal required functionality
because those provided by ST increase code size by almost 2 KiB.
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 7604de3fc2 stmhal/can: clear FIFO flags in IRQ handler
HAL Driver before v1.4.2 had a bug which caused clearing all pending
flags in MSR, TSR, RF0R and RF1R instead of only the requested one.

This is why micropython got away without explicitly clearing flags
in IRQ handler.
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz dc1ac5dc3a stmhal/dma: mark DMA sate as READY even if HAL_DMA_Init is skipped
Current version of HAL drivers checks if `hdma->State == HAL_DMA_STATE_READY`
before executing some functions.
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 63ca7a211a stmhal/dma: precalculate register base and bitshift on handle init
Current version of HAL drivers optimize IRQ handler by using precalculated
DMA register address and stream bitshift instead of calculating it on every interrupt.

Since we skip call to `HAL_DMA_Init` on reused DMA, fields StreamBaseAddress and StreamIndex
of DMA handle are not initialized and thus leads to SegFault in `DMA_IRQHandler`.

HAL_DMA_Init is a big routine and we do not need to call it on each use of DMA
(ex.: series of I2C operations) and DMA_CalcBaseAndBitshift is really small and
releasing it increases code size by only 8 bytes.
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 0280b2c1b1 stmhal/i2c: handle I2C IRQs
This is required by HAL Driver for error handling since v1.5.0
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz fa833f96df stmhal/make-stmconst.py: fix regex's to work with current CMSIS
CMSIS v2.5.0 removed all uint32_t casts and uses only Misra Cast (U)
2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 7928b3e347 stmhal/boards: configure all F4 boards to work with new HAL
changes include:
* use single GPIO.BSRR instead of BSRRH and BSRRL
* change HSE_STARTUP_TIMEOUT to 100 ms
* define LSE_STARTUP_TIMEOUT to 5 s
2016-11-16 12:43:27 +01:00

Krzysztof Blazewicz e8b435d1f8 stmhal: apply STM32CubeF4 v1.13.1 patch - upgrade HAL driver to v1.5.2 2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz c1fa33b493 stmhal: upgrade to STM32CubeF4 v1.13.0 - HAL v1.5.1 2016-11-16 12:43:27 +01:00
Krzysztof Blazewicz 4f5c4fdd98 stmhal: upgrade to STM32CubeF4 v1.13.0 - CMSIS/Device 2.5.1 2016-11-16 12:43:27 +01:00
Damien George e5ef15a9d7 py/lexer: Provide generic mp_lexer_new_from_file based on mp_reader.
If a port defines MICROPY_READER_POSIX or MICROPY_READER_FATFS then
lexer.c now provides an implementation of mp_lexer_new_from_file using
the mp_reader_new_file function.
2016-11-16 18:13:51 +11:00
Damien George 6b239c271c py: Factor out persistent-code reader into separate files.
Implementations of persistent-code reader are provided for POSIX systems
and systems using FatFS.  Macros to use these are MICROPY_READER_POSIX and
MICROPY_READER_FATFS respectively.  If an alternative implementation is
needed then a port can define the function mp_reader_new_file.
2016-11-16 18:13:50 +11:00
Paul Sokolovsky 59a1201da9 all: Remove readall() method, which is equivalent to read() w/o args.
Its addition was due to an early exploration on how to add CPython-like
stream interface. It's clear that it's not needed and just takes up
bytes in all ports.
2016-11-14 00:24:22 +03:00
Damien George 1375c52772 stmhal: Rename mp_hal_pin_set_af to _config_alt, to simplify alt config.
This way the caller doesn't need to initialise a big GPIO_InitTypeDef
struct, and HAL_GPIO_Init is no longer called.
2016-11-11 17:53:45 +11:00
Damien George 74fb5d6932 stmhal/i2c: Reset the I2C peripheral if there was an error on the bus.
If an I2C send/recv fails then the peripheral is now checked to see if
it's in a "stuck" state waiting for the stop bit, and if so then it is
reset so that the next I2C transaction can proceed.

This patch also de-inits the I2C peripheral in the init() method, before
init'ing it again.
2016-11-11 17:38:52 +11:00
Damien George c4e58eaa98 stmhal/i2c: Add option to I2C to enable/disable use of DMA transfers.
New keyword option in constructor and init() method is "dma=<bool>".
DMA is now disabled by default for I2C transfers because it currently does
not handle I2C bus errors very well (eg if slave device doesn't ACK or
NACK correctly during a transfer).
2016-11-11 17:36:19 +11:00
Damien George e6da6a720f stmhal/dma: De-init the DMA peripheral properly before initialising.
The DMA state is always HAL_DMA_STATE_RESET because of the memset clearing
all the data, so prior to this patch HAL_DMA_DeInit was never called.  Now
it is always called to make sure the DMA is properly reset.
2016-11-11 17:24:18 +11:00
Damien George bdf33bc136 py: Move frozen bytecode Makefile rules from ports to common mk files.
Now, to use frozen bytecode all a port needs to do is define
FROZEN_MPY_DIR to the directory containing the .py files to freeze, and
define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL.
2016-11-08 14:28:30 +11:00
Ryan Shaw 8ebd53afc9 stmhal: enable SD power save (disable CLK on idle) 2016-11-07 16:49:29 +11:00
Damien George 7bb0f7b0f6 drivers: Add "from micropython import const" when const is used.
Following best-practice use of the const feature, to make it compatible
with Python.
2016-11-03 12:41:11 +11:00
Damien George cd527bb324 lib/libm: Move Thumb-specific sqrtf function to separate file.
This allows it to be used only when the hardware supports VFP
instructions, preventing compile errors.

Paul Sokolovsky 369233105b stmhal/modutime: Consistently convert to MP_ROM_QSTR/MP_ROM_PTR. 2016-10-29 17:46:47 +03:00
Paul Sokolovsky d86cac4b82 extmod/utime_mphal: Implement ticks_add(), add to all maintained ports. 2016-10-29 17:30:05 +03:00
Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.
2016-10-21 16:26:01 +11:00
Paul Sokolovsky 3967ca7390 stmhal/Makefile: Use standard rules for frozen module generation.

Damien George b4cc68e4a4 stmhal/led: Refactor LED to use mp_hal_pin_output() init function.
As part of this patch the MICROPY_HW_LED_OTYPE setting is removed because
it is now unused (all boards anyway had this as OUTPUT_PP).
