WebAug 9, 2024 · The chip select (CS or SS) to use is determined by which device node you open. To talk to a SPI chip with the Linux spidev driver, you open a device such as /dev/spidev0.1. The numbers in the device node file name refer to the bus and chip select, respectively — in this example it would be the first bus (0) and the second CS (1). WebMay 6, 2024 · For the Ethernet shield, pin 10 is chip select for the Ethernet controller and pin 4 is chip select for the SD card. So you should make pin 10 an output and set it high to disable the Ethernet controller, not because pin 10 is SS. Much confusion results from the fact that on 328 Arduinos pin 10 is also SS.

WebSPI has no handshaking. You just must send no faster than the slave device can handle. In the case of the AD5685R, that is 50 MHz. For multibyte transfer, you keep the chip select asserted (low) between every byte by setting the transferMode to SPI_CONTINUE in the SPI.transfer call. For the last byte, you will deassert the chip select (set it ...
