Hi, I'm currently controlling an AD9914 eval board with an Arduino using SPI. I'm using the 9914's ramp generator to make chirps, and would like to use the DROVER-BUF to trigger a digitizer. Using the 9914 eval board software I can setup the ramp generator and get a signal from the DROVR pins. However, when I switch to Arduino control, I lose the DROVR signal. I set the same register values that the eval board software does, with DROVR output enabled, but get nothing out of the DROVR pin. I'm a bit stumped as to why this is happening and any ideas would be appreciated.
