SPI setup
Posted: Wed Nov 30, 2016 11:12 am
I am attempting to control an Analog Devices DDS chip - the AD9835BRU - from an ExSBC1 card using the SPI port. The Basic call you provide to send bytes uses the SPI protocol with CPOL = CPHA = 0. The DDS chip requires CPOL = 0 and CPHA = 1, however. Is there a way to setup the SPI port to use this protocol??
Thanks,
Charles
