Hi Everett Everett, Your SCLK is still triggering on the wrong edge in the capture (should be on the falling edge). If that is the case for just the analyzer, then that shouldn't affect the communication, just your captures will be wrong. If the controller is capturing data on the wrong edge however, then the communication won't work. Can you send us a schematic? Can you send us pictures of your setup i.e. how is it all connected together? Do you have an EVM you could try? This can act as a baseline for your board, so you know what the communication should look like and because the EVM analog / digital circuitry has been tested -Bryan
