Damien George 1608c4f5be stm32/can: Use enums to index keyword arguments, for clarity. 2018-03-15 17:15:41 +11:00
Damien George 2036196d71 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.

Damien George 22a9158ced stm32/boards/STM32L476DISC: Enable CAN peripheral.
This board allows to test CAN support on the L4 series.

Damien George d91a1989f5 docs/library/pyb.CAN: Update markup to use latest doc conventions. 2018-03-15 16:30:05 +11:00
Damien George 0db49c37a4 docs: Fix some references and RST markup to eliminate Sphinx warnings. 2018-03-15 15:50:51 +11:00
Damien George c926e72750 tests/cpydiff: Indent workaround code snippet so it formats correctly. 2018-03-15 15:49:38 +11:00
Damien George 34e224a4af 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.

Damien George bdc875e602 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.

Damien George e0bc438e4b py/obj.h: Move declaration of mp_obj_list_init to objlist.h.
If this function is used then objlist.h is already included to get the
definition of mp_obj_list_t.

Damien George 9f811e9096 py/obj.h: Clean up by removing commented-out inline versions of macros. 2018-03-13 14:01:55 +11:00
Damien George d4b55eff44 py/misc.h: Remove unused count_lead_ones() inline function.
This function was never used for unicode/utf8 handling code, or anything
else, so remove it to keep things clean.

Damien George 033c32e694 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.

Tom Collins 4d3a92c67c extmod/vfs_fat: Add file size as 4th element of uos.ilistdir tuple. 2018-03-12 12:26:36 +11:00
Damien George 1345093401 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.

Damien George cc34b087f0 drivers/memory/spiflash: Fix setting of QE bit in flash register. 2018-03-11 11:25:38 +11:00
Damien George 0d5bccad11 stm32/storage: Provide support for a second block device. 2018-03-10 01:03:27 +11:00
Damien George bb3359f357 stm32/boards/STM32L476DISC: Provide SPI-flash bdev config.
This board shows how to configure external SPI flash as the main storage
medium.  It uses software SPI.
2018-03-10 00:59:43 +11:00
Damien George 626d6c9756 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.
2018-03-10 00:59:43 +11:00
Damien George d1c4bd69df 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.
2018-03-10 00:59:43 +11:00
Damien George 1803e8ef22 stm32/storage: Make spi_bdev interface take a data pointer as first arg.
This allows a board to have multiple instances of the SPI block device.
2018-03-10 00:59:43 +11:00
Damien George 1e4caf0b1e stm32/storage: Merge all misc block-dev funcs into a single ioctl func.
It makes it cleaner, and simpler to support multiple different block
devices.  It also allows to easily extend a given block device with new
ioctl operations.

Damien George a739b35a96 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
Damien George 58ebeca6a9 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.
