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.
stmhal: Improve efficiency of SysTick IRQ and HAL_Delay.2014-08-25T17:12:44+00:00Damien Georgedamien.p.george@gmail.com2014-08-25T17:12:44+00:00urn:sha1:34e43c7ee9700249dc6e5b333b7c264d45d6b530
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.
stmhal: Use MP_OBJ_NEW_SMALL_INT directly in pyb.micros/millis.2014-08-25T16:38:55+00:00Damien Georgedamien.p.george@gmail.com2014-08-25T16:36:14+00:00urn:sha1:29c92a407c8fa04a205f10c4efdb5696e0cf0b58
Also some whitespace cleanup.
Add support for pyb.micros() by using the systick timer.2014-08-25T16:38:55+00:00Dave Hylandsdhylands@gmail.com2014-08-23T19:21:12+00:00urn:sha1:2bf044442eae7dbdaff91051d2c135b4aa51f1b2
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)
stmhal: Include mpconfig.h before all other includes.2014-06-28T20:32:03+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-06-28T20:32:03+00:00urn:sha1:8139494e54b5ad1630f30490216e9486b976bdb8
It defines types used by all other headers.
Fixes #691.
Add license header to (almost) all files.2014-05-03T22:27:38+00:00Damien Georgedamien.p.george@gmail.com2014-05-03T22:27:38+00:00urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28
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/.
