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)
2015-10-29 16:03:10 +00:00
// The unique id address differs per MCU. Ideally this define should
// go in some MCU-specific header, but for now it lives here.

all: Add py/mphal.h and use it in all ports. py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations.

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()))) ```

stmhal: Use OSError with POSIX error code for HAL errors. Addresses issue #921.

stmhal: Factor GPIO clock enable logic into mp_hal_gpio_clock_enable. Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable and called from anyplace which might need to use GPIO functions on ports other than A-D. Thanks to Dave Hylands for the patch.

stmhal: Reduce coupling between USB driver and readline. This makes it easier to re-use readline.c and pyexec.c from stmhal in other ports.

void mp_hal_set_interrupt_char(int c); // -1 to disable
stmhal: Make pybstdio usable by other ports, and use it. Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

unix, stmhal: Introduce mp_hal_delay_ms(), mp_hal_ticks_ms(). These MPHAL functions are intended to replace previously used HAL_Delay(), HAL_GetTick() to provide better naming and MPHAL separation (they are fully equivalent otherwise). Also, refactor extmod/modlwip to use them.
