    Custom Function Generator

    Hi Vonmuller, Thanks for the code for Pmod ad2. It's really wonderfull. I tried to use the same logic to make ad2 works in high speed mode but I couldn't make it. I followed the sequence showed in page 25 of the ad7991 datasheet but there is no way I can make it work in high speed. Actually, I tried diferent frequencies but only 100khz is switable. I noted that in that diagram, high speed mode is configured since fast mode, but in datasheet there is nothing about how to configure ad7991 in fast mode. Can you help me with this? Any ideas?

    Well Jon, I don't have arduino yet. But thank you anyway. The logic should be the same. Thanks, Danny

    Pmod IOXP: I/O Expansion Module

    Hi Jon. Actually, I was working on my own vhdl code for a specific aplication with high speed in ISE software because in the resource center I haven't found a code for high speed mode, only standar mode, which works perfect. thanks, Danny

    Pmod IOXP: I/O Expansion Module

    Hi JColvin, I am using Nexys 4 and trying to make Pmod AD2 works in high speed (3.4Mhz) but I couldn't. I used the code diligent provided and works fine but only in standar mode (100khz). I followed the sequence showed in page 25 of AD7991 datasheet but there is no way I can make it work. It also says something about fast mode (400khz) but I haven't found any instruction to put ad7991 in fast mode neither. Do you have something that can help me to work in high speed mode? I will really apreciate it. Regards, Danny
