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.

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

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)

e5cbb70328 stmhal: Make enable_irq and disable_irq inline functions. 
These functions are generally 1 machine instruction, and are used in
critical code, so makes sense to have them inline.

Also leave these functions uninverted (ie 0 means enable, 1 means
disable) and provide macro constants if you really need to distinguish
the states.  This makes for smaller code as well (combined with
inlining).

Applied to teensy port as well.

3c658a4e75 py: Fix bug where GC collected native/viper/asm function data. 
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

25fc41dd31 unix, modtermios: Make it properly configurable; fix spelling mistake. 2014-08-24 13:19:22 +01:00
Paul Sokolovsky
4f9ebade60 modtermios: Add "termios" unix module, subset of CPython's. 
Also provides setraw() function from "tty" module (which in CPython is
implemented in Python). The idea here is that 95% of "termios" module usage
is to set raw mode to allow access to normal serial devices. Then, instead
of exporting gazillion termios symbols, it's better to implement it in C,
and export minimal number of symbols (mostly baud rates and drain values).

26a0d4f4f1 py: Change hash and len members of str from 16 bit to full word.

This simple patch gives a very significant speed up for memory allocation
with the GC.

tests/misc/rge_sm.py:     15.3 seconds -> 2.48 seconds

b63be37be1 stmhal: In safe mode, still mount SD card and present as MSD over USB. 
It's still "safe" because no scripts are run.  Remove the SD card if you
want to access the internal flash filesystem.  Addresses issue #616.

Also: remove obsolete pyb.source_dir setting, and reset pyb.main and
pyb.usb_mode settings on soft-reset.
