a4a439caa3 examples/button_reaction: Update for time_pulse_us() no longer raising exc. 2017-02-05 18:01:42 +03:00
Paul Sokolovsky
d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions. 
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.

bd04ed3e8a py/objcomplex: Fix typo in ternary expression. 
This typo actually did the correct thing, but it was very obscure (came
about from think in terms of Python's "x if cond else y" expression).

a19b5a01ce py/mpconfig.h: Move PY_BUILTINS_POW3 config option to diff part of file. 
With so many config options it's good to (at least try to) keep them
grouped into logical sections.

7317e34383 py/objstr: Give correct behaviour when passing a dict to %-formatting. 
This patch fixes two main things:
- dicts can be printed directly using '%s' % dict
- %-formatting should not crash when passed a non-dict to, eg, '%(foo)s'

df0117c8ae py: Added optimised support for 3-argument calls to builtin.pow() 
Updated modbuiltin.c to add conditional support for 3-arg calls to
pow() using MICROPY_PY_BUILTINS_POW3 config parameter. Added support in
objint_mpz.c for for optimised implementation.

882ec01e42 stmhal: Initial implementation of multithreading, currently disabled. 
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.

3667ee1b88 stmhal: On boot, mount all available partitions of the SD card. 
The first partition is mounted as "/sd" and subsequent partitions are
mounted as "/sd<part_num>".  This is backwards compatible with the previous
behaviour, which just mounted the first partition on "/sd".

At this point, only FatFs filesystems are mounted.
