The renames are:
HAL_Delay -> mp_hal_delay_ms
sys_tick_udelay -> mp_hal_delay_us
sys_tick_get_microseconds -> mp_hal_ticks_us
And mp_hal_ticks_ms is added to provide the full set of timing functions.
Also, a separate HAL_Delay function is added which differs slightly from
mp_hal_delay_ms and is intended for use only by the ST HAL functions.
This patch brings the _thread module to stmhal/pyboard. There is a very
simple round-robin thread scheduler, which is disabled if there is only
one thread (for efficiency when threading is not used).
The scheduler currently switches threads at a rate of 250Hz using the
systick timer and the pend-SV interrupt.
The GIL is disabled so one must be careful to use lock objects to prevent
concurrent access of objects.
The threading is disabled by default, one can enabled it with the config
option MICROPY_PY_THREAD to test it out.
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.
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
