WebThere’s currently no way to report the actual bit rate used to shift data to/from a given device. From userspace, you can’t currently change the chip select polarity; that could corrupt transfers to other devices sharing the SPI bus. Each SPI device is deselected when it’s not in active use, allowing other drivers to talk to other devices.
