I was wondering if someone could help me to program the AD9959 Eval Board step by step using an FPGA. I am not an expert in this kind of things (SPI protocol) so, I will appreciate any help from anyone.
1. Do I have to send a clock in the pin "SCLK" from the FPGA? When I send this clock, I also have to send the bit information in STDIO_0?
2.To change from one register to another do I have to send a signal to I_O Update pin?
3. Do I have to send always a signal to the pin "Reset" when I start to send the register infromation (series of 1 and 0) from the FPGA to the AD9959?
What else do I need to have in mind?
Thanks so much for your help.
