8844d031e4 stmhal: Add support for the STM32F429I-DISCO kit by STMicro. 2015-11-25 23:53:26 +00:00

f32020ef3d py/mpconfig.h: Allow to build without alloca() for ANSI C compliance.
Define MICROPY_NO_ALLOCA=1 and memory will be allocated from heap instead
and freed by garbage collection.

c8437f97ae stmhal: Increase the priority of UART IRQ.
The UARTs have no FIFOs, so if interrupts are disabled
for more than a character time (10 usec at 1 Mbit/sec)
then characters get dropped.

The overhead for handling a UART ISR is about 0.5 usec,
so even at baud rates of 1 Mbit/sec this only corresponds
to about 5% of the CPU. Lower baud rates will have less
of an impact.

ff8c4188f4 tests/run-tests: Improve robustness of REPL tests.
Unconditionally wait for MicroPython banner. On overloaded systems, when
using emulators, etc. initial executable startup may take more than 20ms.

36bd10779c stmhal: In SysTick IRQ handler, make uwTick variable non-volatile.
uwTick can only change in the SysTick IRQ so this IRQ function does not
need to take special care with this variable.  It's important to make
this IRQ function as efficient as possible.

e99e6c883d stmhal: Move flash storage idle tick handler from TIM3 to SysTick.
Using SysTick to do the counting and dispatch of the flash storage idle
handler is more efficient than requiring a dedicated hardware timer.
No new counter is needed, just the existing uwTick variable.  The
processing is not actually done in the SysTick IRQ, it is deferred to
the flash IRQ (which runs at lower priority).

22bd23114a stmhal: On SysTick IRQ, only process one DMA channel at a time.
This can be generalised if/when more processing is needed by SysTick.

Thanks to @chuckbook for the idea.

3baf6b5319 windows/py: Support 64bit mingw-w64 builds
- add mp_int_t/mp_uint_t typedefs in mpconfigport.h
- fix integer suffixes/formatting in mpconfig.h and mpz.h
- use MICROPY_NLR_SETJMP=1 in Makefile since the current nlrx64.S
  implementation causes segfaults in gc_free()
- update README

a58fa27c24 windows: Cleanup makefile
The BSD stuff is a copy from the unix makefile but at least there it
makes some sense, a windows makefile on BSD doesn't.
The -lmman flag is probably for mmap functions but there is no other build
support for it on windows so just that flag won't cut it anyway.

b677f03407 stmhal: Turn off DMA clocks when idle for 100 msec
Turning on each DMA block increases the current consumption
by about 8 mA. This code adds an idle timer for each DMA
block and turns off the clocks when no streams are in use
for 128 msec. Having a small timeout allows for improved
performance when back-to-back transfers are being performed.

The 128 msec is basically a guess.

9f5486c7e2 stmhal: Put IRQs into priority order.
- added some comments to explain the priority/sub-priority.
- adds an entry for SDIO (to be used in a later patch)
- increases DMA priority above USB so that DMA can be used
  for sdcard I/O when using USB Mass Storage.

86aa16bea6 stmhal: Implement delayed RTC initialization with LSI fallback.
If RTC is already running at boot then it's left alone.  Otherwise, RTC is
started at boot but startup function returns straight away.  RTC startup
is then finished the first time it is used.  Fallback to LSI if LSE fails
to start in a certain time.

Also included:
 MICROPY_HW_CLK_LAST_FREQ
        hold pyb.freq() parameters in RTC backup reg
 MICROPY_HW_RTC_USE_US
        option to present datetime sub-seconds in microseconds
 MICROPY_HW_RTC_USE_CALOUT
        option to enable RTC calibration output

CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

9aaccd4735 py/formatfloat: Convert to fully portable implementation.
This takes previous IEEE-754 single precision float implementation, and
converts it to fully portable parametrizable implementation using C99
functions like signbit(), isnan(), isinf(). As long as those functions
are available (they can be defined in adhoc manner of course), and
compiler can perform standard arithmetic and comparison operations on a
float type, this implementation will work with any underlying float type
(including types whose mantissa is larger than available intergral integer
type).

3ba61656bd unix/modsocket: Implement sockaddr() function to decode raw socket address.
Return tuple of (address_family, net_addr, [port, [extra_data]]). net_addr
is still raw network address as bytes object, but suitable for passing to
inet_ntop() function. At the very least, sockaddr() will separate address
family value from binary socket address (and currently, only AF_INET family
is decoded).
