Damien George af622eb2a6 py/map: Change mp_uint_t to size_t where appropriate.
The internal map/set functions now use size_t exclusively for computing
addresses.  size_t is enough to reach all of available memory when
computing addresses so is the right type to use.  In particular, for
nanbox builds it saves quite a bit of code size and RAM compared to the
original use of mp_uint_t (which is 64-bits on nanbox builds).

Damien George a25aa2bcc3 py/asmxtensa.h: Explicitly cast args to 32-bits so left-shift is legal.
For archs that have 16-bit pointers, the asmxtensa.h file can give compiler
warnings about left-shift being greater than the width of the type (due to
the inline functions in this header file).  Explicitly casting the
constants to uint32_t stops these warnings.

Damien George 8400351d5a stmhal: Use MICROPY_EVENT_POLL_HOOK instead of __WFI where appropriate. 2017-02-06 15:10:03 +11:00
Damien George dee47949cc extmod/machine_spi: Remove EVENT_POLL_HOOK from soft-SPI transfer func.
SPI needs to be fast, and calling the EVENT_POLL_HOOK every byte makes it
unusable for ports that need to do non-trivial work in the EVENT_POLL_HOOK
call.  And individual SPI transfers should be short enough in time that
EVENT_POLL_HOOK doesn't need to be called.

If something like this proves to be needed in practice then we will need
to introduce separate event hook macros, one for "slow" loops (eg
select/poll) and one for "fast" loops (eg software I2C, SPI).

Damien George d3bb3e38df tests/pyb: Adjust tests so they can run on PYB and PYBLITE.
A few tests still fail on PYBLITE, and that's due to differences in the
available peripheral block numbers on the different MCUs (eg I2C(2)
exists on one, but it's I2C(3) on the other).

Damien George 27c149efe0 stmhal: Add pyb.fault_debug() function, to control hard-fault behaviour.
This new function controls what happens on a hard-fault:
- debugging disabled: board will do a reset
- debugging enabled: board will print registers and stack and flash LEDs

The default is disabled, ie to do a reset.  This is different to previous
behaviour which flashed the LEDs and waited indefinitely.

Damien George b7d27e31e8 cc3200: Refactor "ticks" functions to use common extmod implementation.
The port now uses the common mp_utime_ticks_{ms,us,cpu,add,diff} functions
from extmod/utime_mphal.c.

The mp_utime_sleep_XXX functions are still cc3200-specific because they
handle the GIL differently to the ones in extmod.

The files misc/mpsystick.[ch] have been removed because they contain 2
unused functions, and the other remaining function is renamed to
mp_hal_ticks_us and moved to hal/cc3200_hal.c.

Paul Sokolovsky 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.

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).

Damien George 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.

The first partition is mounted as "/sd" and subsequent partitions are

behaviour, which just mounted the first partition on "/sd".

At this point, only FatFs filesystems are mounted.
