Web WebNov 5, 2016 · As long as the Chip Select pin of your slave device is high it doesn't care what goes on with the clock or data lines. It makes no sense to add a pull-up to the clock since the only time the slave cares about what happens on that line is when you are actively doing an SPI transaction.

WebChip select bit. Inverted with respect to SPI chip select, which is normally active low. 1: Selects the Flash chip (CS pin = 0) 0: Flash chip not selected (CS pin = 1) 26 XFER 0 1: Start sending NBYTES over SPI 0: No effect This bit clears itself automatically 25..24 NBYTES 0 Number of bytes to send during one transfer 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 ... WebJul 3, 2024 · The protocol of communication with my chip is the SPI.
