This is a big update! I've been working with Eric Lin to move most of the FED3 functions into a library. The idea is to have FED3 handle most of what it does (monitoring pokes, logging data, updating screen) in a library behind the scenes, and users can focus on just coding their behavioral tasks.
It's not done but it is at a point where it's ready for testing. You can see it in action
here.
If you're interested in testing this out or helping with this please get in touch and I can share it with you!
