py/makeqstrdefs.py: Optimise by using compiled re's so it runs faster.
...
By using pre-compiled regexs, using startswith(), and explicitly checking
for empty lines (of which around 30% of the input lines are), automatic
qstr extraction is speed up by about 10%.

stm32/can: Use explicit byte extraction instead of casting to word ptr.
...
Casting the Data array to a uint32_t* leads to strict aliasing errors on
older gcc compilers.

stm32/can: Improve can.recv() so it checks for events, eg ctrl-C.
...
This patch provides a custom (and simple) function to receive data on the
CAN bus, instead of the HAL function. This custom version calls
mp_handle_pending() while waiting for messages, which, among other things,
allows to interrupt the recv() method via KeyboardInterrupt.

esp32/machine_uart: Return None from UART read if no data is available.

This is instead of returning an empty bytes object, and matches how other
ports handle non-blocking UART read behaviour.

drivers/memory/spiflash: Fix bugs in and clean up read/write functions.
...
mp_spiflash_read had a bug in it where "dest" and "addr" were incremented
twice for a certain special case. This was fixed, which then allowed the
function to be simplified to reduce code size.
mp_spiflash_write had a bug in it where "src" was not incremented correctly
for the case where the data to be written included the caching buffer as
well as some bytes after this buffer. This was fixed and the resulting
code simplified.

py/obj.h: Move declaration of mp_obj_list_init to objlist.h.

else, so remove it to keep things clean.

esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high.
...
Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver. To work
around this make the pin an input to let it float high.

stm32/qspi: Do an explicit read instead of using memory-mapped mode.
...
Using an explicit read eliminates the need to invalidate the D-cache after
enabling the memory mapping mode, which takes additional time.

stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg.
...
This config variable controls whether to support storage on the internal
flash of the MCU. It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.

stm32/storage: Remove all SPI-flash bdev cfg, to be provided per board.

If a board wants to use SPI flash for storage then it must now provide the
configuration itself, using the MICROPY_HW_BDEV_xxx macros.

ioctl operations.

drivers/memory/spiflash: Change to use low-level SPI object not uPy one.
...
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h). This allows the SPI-flash driver to
be used independently from the uPy runtime.
2018-03-10 00:59:43 +11:00

drivers/bus: Pull out software SPI implementation to dedicated driver.
...
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c. This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.
