openmano-mpy/drivers/bus, branch master MicroPython source and hardware configuration for OpenMano drivers, stm32: Support SPI/QSPI flash chips over 16MB. 2020-01-30T02:18:38+00:00 Andrew Leech 2020-01-28T03:59:05+00:00 30501d3f54fa642770faefa117b4c39d95aff549 With a SPI flash that has more than 16MB, 32-bit addressing is required rather than the standard 24-bit. This commit adds support for 32-bit addressing so that the SPI flash commands (read/write/erase) are selected automatically depending on the size of the address being used at each operation.

drivers/bus: Pull out software SPI implementation to dedicated driver. 2018-03-09T13:59:43+00:00 Damien George 2018-03-09T06:25:58+00:00 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/bus: Add QSPI abstract type with software QSPI implementation. 2018-03-02T12:52:59+00:00 Damien George 2018-03-01T23:44:38+00:00 1da2d45de6363d4014d379b78f114cd3d1649d7b A new directory drivers/bus/ is introduced, which can hold implementations of bus drivers. A software QSPI implementation is added.
