Dear Good people,
I am trying to perform the external control of the Ad9959 evaluation board via the ardiuno uno board. Initially, I want to generate 1 MHz frequency for all the DAC outputs. I set W7 to manual and removed W1, W2, W3, and W10.
Here is my pin connections
Ardiuno clock 13 to sck of Ad9959 (U2 row)
Pin 4 to Reset Ad9959 (U2 row)
Pin 7 to I/O update of Ad9959 (U2 row)
Mosi 11 to SDIO_0 of Ad9959 (U2 row)
I did not face any error while uploading the code in ardiuno. But the evaluation board is not responding at all. I am attaching the code for your review. Where could be the possible error? Please help me.
