stmhal: Use OSError with POSIX error code for HAL errors. Addresses issue #921.
2014-10-23 14:25:32 +01:00
#include <errno.h>
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.

#include "py/mpstate.h"
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.

#include "py/mphal.h"
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.

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.
