I have decided to attempt building my own evaluation board along with an Arduino microcontroller, and I've mostly figured out how to interface to each of the AD9910 pins. The only question I have now is how I would access the registers through the serial port? Do I simply send in the appropriate hexadecimal value and the DDS chip will automatically go to that register? Or must I send in some sort of notification signal before telling it which register I want to access?
