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. 2014-07-02 08:42:37 -04:00			`// We use the ST Cube HAL library for most hardware peripherals`

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()))) ``` 2014-07-22 10:57:36 -04:00			`#define GPIO_read_output_pin(gpio, pin) (((gpio)->ODR >> (pin)) & 1)`
