Kerry, 

I'm new to programming the arduino and I intend to build the digital attenuator boards. I would appreciate it if you could comment whether the code you/Kevin have posted would also work with the 4D Systems display if I use the right serial library ?.

If I want the 4D display to be used as an input, presumably it just needs to pass one variable back to the controller and to increment the volume parameter up or down irrespective of whether the variable change comes from the 4D display or the  encoder? The 4D display has commands to write values back to the display and I have used the 4D systems software to create code. What is the general approach to merging the 4D code generated and what you have produced?  

Do you have a list of the variables used in the code and what they do to assist? (if not, I will work through it).

I am wondering whether I might be better off just buying the oled dispay and forgetting the 4D, at least for now.
