Entschuldigung, ich spreche kein Deutsch.That code looks great and well written. It appears you have done this many times before. I will try to translate this weekend and see what I can make of it. Can you give the make and model of your Mastervolt device. I am use to Cory J Fowler's library. It is similar to something I am working on but all the targets are my design. More as I get into it.
