Merge branch 'teensy-new' of github.com:dhylands/micropython into dhylands-teensy-new Conflicts: stmhal/pin_named_pins.c stmhal/readline.c Renamed HAL_H to MICROPY_HAL_H. Made stmhal/mphal.h which intends to define the generic Micro Python HAL, which in stmhal sits above the ST HAL.

// We use the ST Cube HAL library for most hardware peripherals
stmhal: Replace #include "stm32f4xx_hal.h" with #include STM32_HAL_H.
2015-07-28 16:36:26 +01:00
#include STM32_HAL_H
stmhal: Add a function for setting the pin alternate function mp_hal_gpio_set_af will search for a given function and unit and set the alternate function to the alternate function index found.

stmhal: Add define for UNIQUE_ID address (differs per MCU)

// The unique id address differs per MCU. Ideally this define should
// go in some MCU-specific header, but for now it lives here.

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.

Add support for selecting pin alternate functions from python. Converts generted pins to use qstrs instead of string pointers. This patch also adds the following functions: pyb.Pin.names() pyb.Pin.af_list() pyb.Pin.gpio() dir(pyb.Pin.board) and dir(pyb.Pin.cpu) also produce useful results. pyb.Pin now takes kw args. pyb.Pin.__str__ now prints more useful information about the pin configuration. I found the following functions in my boot.py to be useful: ```python def pins(): for pin_name in dir(pyb.Pin.board): pin = pyb.Pin(pin_name) print('{:10s} {:s}'.format(pin_name, str(pin))) def af(): for pin_name in dir(pyb.Pin.board): pin = pyb.Pin(pin_name) print('{:10s} {:s}'.format(pin_name, str(pin.af_list()))) ```
