    How to make it works in high speed mode?

    Posted by Daniel Guevara on 2nd Apr 2018

    I really liked very much pmod AD2. It works perfectly in standard mode, but I have made several codes trying to make it work in fast mode and high speed mode (following the parameters of the AD7991 specifics) without any success. This is crucial for me for the application I need to work. Can I get some help about this?
