Trouble Communicating via SPI with AD7192

Dear Analog Devices Community,


I am trying to communicate with the AD7192 via SPI and I am having trouble. Right now I'm looking at the DOUT/RDY pin on the scope and oddly the pin stays low and is pulsing high at about 1kHz. Is this a known bug? I have performed resets and I am just trying to read from a register. From what I understand, I send a byte to the comm register signifying a read command, then the next pulses to SCLK I should be able to read from the chosen register. Is there a specific SCLK frequency I need to choose?

 

Thank you,

 

Anthony
