      stmhal: Big cleanup; merge gpio into Pin; make names consistent. · c66d86c5
      Damien George authored
      This is an attempt to clean up the Micro Python API on the pyboard.
      Gpio functionality is now in the Pin object, which seems more natural.
      Constants for MODE and PULL are now in pyb.Pin.  Names of some
      classes have been adjusted to conform to CamelCase.  Other
      miscellaneous changes and clean up here and there.

      stmhal - fixed up adc stuff · 1403298a
      Dave Hylands authored
      Added support for the ADC channels and mappings to make_pins.py
      
      I'm not sure if the hal properly deals with the channel 16/18 differences
      between the 40x and 42x. It seems to deal with it partially. This particular
      aspect will need testing on a 42x or 43x.

      Initial checkin with STM HAL · dd38d907
      Dave Hylands authored
      This compiles and links, but hasn't been tested on a board
      yet and even if it was run, it doesn't currently do anything.

      Add pin mapping code. · 51dabac0
      Dave Hylands authored
      This commit also introduces board directories and moves board
      specific config into the appropriate board directory.
      
      boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
      and hand-tweaked.
      
      make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
      and boards/BOARD-NAME/pins.csv as input and generates the file
      build/pins_BOARD_NAME.c
      
      The generated pin file for PYBOARD4 looks like this:
      https://gist.github.com/dhylands/9063231
      
      The generated pins file includes all of the supported alternate
      functions, and includes upsupported alternate functions as comments.
      
      See the commnet block at the top of stm/pin_map.c for details on
      how to use the pin mapper.
      
      I also went ahead and modified stm/gpio.c to use the pin mapper.
