SPISlaveDevice provides a chip-specific interface to the SPI Slave hardware. The interface wraps the chip select line so that chip drivers cannot communicate with different SPI devices.

Required Methods

[−]

Setup the SPI settings and speed of the bus.

[−]

Perform an asynchronous read/write operation, whose completion is signaled by invoking SpiSlaveClient.read_write_done on the provided client. Either write_buffer or read_buffer may be None. If read_buffer is Some, the length of the operation is the minimum of the size of the two buffers.
