Damien George 2cf6dfa280 stmhal: Prefix includes with py/; remove need for -I../py. 2015-01-01 21:06:20 +00:00
Damien George 1960475ed7 stmhal: Make pyb.[u]delay use systick with IRQs, busy loop otherwise.
pyb.delay and pyb.udelay now use systick if IRQs are enabled, otherwise
they use a busy loop.  Thus they work correctly when IRQs are disabled.
The busy loop is computed from the current CPU frequency, so works no
matter the CPU frequency.

Damien George 34e43c7ee9 stmhal: Improve efficiency of SysTick IRQ and HAL_Delay.
SysTick IRQ now increases millisecond counter directly (ie without
calling HAL_IncTick).  Provide our own version of HAL_Delay that does a
wfi while waiting.  This more than halves power consumption when running
a loop containing a pyb.delay call.  It used to be like this, but new
version of HAL library regressed this feature.

Damien George 29c92a407c stmhal: Use MP_OBJ_NEW_SMALL_INT directly in pyb.micros/millis.
Also some whitespace cleanup.

Dave Hylands 2bf044442e Add support for pyb.micros() by using the systick timer.
I also removed trailing spaces from modpyb.c which affected a couple
of lines technically not part of this patch.

Tested using: https://github.com/dhylands/upy-examples/blob/master/micros_test.py

which eventually fails due to wraparound issues (I could fix the test to compensate
but didn't bother)

Paul Sokolovsky 8139494e54 stmhal: Include mpconfig.h before all other includes.
It defines types used by all other headers.

Fixes #691.

Damien George 04b9147e15 Add license header to (almost) all files.
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/.
