suspect-devices/circuitpython/drivers, branch v1.9.4CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.9.42018-03-13T03:13:30+00:00drivers/memory/spiflash: Fix bugs in and clean up read/write functions.2018-03-13T03:13:30+00:00Damien Georgedamien.p.george@gmail.com2018-03-13T03:13:30+00:00urn:sha1:bdc875e602f687bf0fb28c3a18565ffec4157f59
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.
drivers/memory/spiflash: Fix setting of QE bit in flash register.2018-03-11T00:25:38+00:00Damien Georgedamien.p.george@gmail.com2018-03-11T00:25:38+00:00urn:sha1:cc34b087f0fe121afb03dcfe99180737ab925372drivers/memory/spiflash: Change to use low-level SPI object not uPy one.2018-03-09T13:59:43+00:00Damien Georgedamien.p.george@gmail.com2018-03-09T06:32:28+00:00urn:sha1:a739b35a9618c2dd2d25c9ef4d076eeffddbb399
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.
drivers/bus: Pull out software SPI implementation to dedicated driver.2018-03-09T13:59:43+00:00Damien Georgedamien.p.george@gmail.com2018-03-09T06:25:58+00:00urn:sha1:58ebeca6a9a172a35b9298a911d450722797c409
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.
drivers/memory/spiflash: Add support for QSPI interface.2018-03-02T12:54:09+00:00Damien Georgedamien.p.george@gmail.com2018-03-02T05:01:18+00:00urn:sha1:4e48700f9a284ab73fc199610314f2f6484adbfc
The spiflash memory driver is reworked to allow the underlying bus to be
either normal SPI or QSPI. In both cases the bus can be implemented in
software or hardware, as long as the spiflash driver is passed the correct
configuration structure.
drivers/bus: Add QSPI abstract type with software QSPI implementation.2018-03-02T12:52:59+00:00Damien Georgedamien.p.george@gmail.com2018-03-01T23:44:38+00:00urn:sha1:1da2d45de6363d4014d379b78f114cd3d1649d7b
A new directory drivers/bus/ is introduced, which can hold implementations
of bus drivers. A software QSPI implementation is added.

machine.SPI(0) results in ValueError on ESP8266. SPI(1) is the user
hardware SPI port (or use SPI(-1) for software SPI).
