Dave Hylands fedab995ee stmhal: Set STM32F7DISC CPU Frequency to 216 MHz
This set the CPU frequency to 216 MHz (the max) and
leaves the USB Frequency at 48 MHz.

These settings were copied from one of the HAL examples.

Damien George 76c366df56 stmhal: Add machine.WDT class.
Usage:

    import machine
    wdt = machine.WDT(0, 5000) # 5 second timeout
    wdt.feed()

Thanks to Moritz for the initial implementation.

Damien George 9c04ef2a67 unix,stmhal,esp8266: When find'ing frozen files don't use extra slash.
This extra forward slash for the starting-point directory is unnecessary
and leads to additional slashes on Max OS X which mean that the frozen
files cannot be imported.

Fixes #2374.

Krzysztof Blazewicz fc73c9b4b2 stmhal/modusocket: set self->nic to MP_OBJ_NULL after socket close
This patch makes second and next calls to <socket>.close() a no-op.
It prevents GC from closing the underlying resource after user
already used <socket>.close() explicitly.

Dave Hylands a589fa3e0b stmhal: Update pin print to print new constants
This updates the print function for machine.Pin to

rather than the legacy definitions.

Damien George d2d9dfcd40 stmhal: Remove obsolete code for special handling of TIM3 irq settings.
TIM3 is no longer special, or at least does not have special IRQ settings.

Dave Hylands c6983e3ce0 stmhal: Fix timer capture/compare interrupt handling for TIM1 and TIM8.
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.

So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.

During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.

I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8

Damien George 675d1c9c60 ports: Remove typedef of machine_ptr_t, it's no longer needed.
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation.  So we can now remove this unused typedef,
to simplify the mpconfigport.h file.

Tobias Badertscher af9889f99a stmhal/adc.c: Get ADC working on STM32L4 MCUs.
Fixing Issue #2243. Main problems were:

- HAL_ADC_GetState(adcHandle) may return other bits set (not only
  HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
  mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
  GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
  generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
  is done in two functions.

Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.

Thanks to mattbrejza for discovering the bug.

    f = open('test', 'rb') # test must be 1024 bytes or more in size
    f.seek(511)
    f.read(513)

Also works for writing.

Tobias Badertscher e64032d6fd stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series.
The main thing is to change the DMA code in a way that the structure
DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4)
is no longer used outside of dma.c, as this structure only exists for the
F4 series.  Therefore I introduced a new structure (dma_descr_t) which
handles all DMA specific stuff for configuration.  Further the periphery
(spi, i2c, sdcard, dac) does not need to know the internals of the dma.

the docs.

Tobias Badertscher 495da15611 stmhal: L4: Add support for external interrupts/events.
The L4 MCU supports 40 Events/IRQs lines of the type configurable and
direct.  But this L4 port only supports configurable line types which are
already supported by uPy.  For details see page 330 of RM0351, Rev 1.

The USB_FS_WAKUP event is a direct type and there is no support for it.

Tobias Badertscher dda1a41205 stmhal: L4: Modify mphalport to support L4 MCU.
__GPIOI_CLK_ENABLE is defined in hal/l4/inc/Legacy/stm32_hal_legacy.h
as __HAL_RCC_GPIOI_CLK_ENABLE, and that latter macro is not defined
anywhere else (because the L4 does not have port GPIOI).  So the test
for GPIOI is needed, along with the test for the CLK_ENABLE macro.

Tobias Badertscher d4c3349957 stmhal: L4: Adapt UART HAL to avoid 64-bit integer division.
64-bit integer division brings a dependency on library functions. It is

Jan Čapek d76c65f599 py: Add rules for automated extraction of qstrs from sources.
- add template rule that converts a specified source file into a qstring file

- add special rule for generating a central header that contains all
  extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
  variable. Each platform appends a list of sources that may contain
  qstrings into a new build variable: SRC_QSTR. Any autogenerated
  prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.

- remove most qstrings from py/qstrdefs, keep only qstrings that
  contain special characters - these cannot be easily detected in the
  sources without additional annotations

- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
  stmhal, teensy, unix, windows, pic16bit:

   - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
   - remove all port specific qstrdefs except for special strings
   - append sources for qstr generation in platform makefiles (SRC_QSTR)

Paul Sokolovsky 9e0478a902 stmhal/diskio: Add provision for default returns for ioctl INIT/SEC_SIZE.
If None was returned for such requests (which likely means that user simply
didn't handle them), it means successful init and default sector size of 512
bytes respectively. This makes only BP_IOCTL_SEC_COUNT a mandatory request,
and thus re-establishes parity with old interface, where only .count() is
mandatory().
