Well cannot get the reader to see the Atmel chip. Do Atmel chips require anything to prepare them for loading the .hex file onto them? Mine is not showing up at all. Which leads me to believe that the chip is fried or the circuit is broken on paths to the Atmel. Ask anything even questions considered dumb. Never programmed an IC before, unless you count Dediprog.

I'm assuming the barrel plug needs to be there. That would probably be the problem. Sent from my SM-G955U using Tapatalk -

So I acquired this today. Am not sure if I should open it or not. Is there a large calling for Unisys Mice? I can't find anything on this model. Sent from my SM-G955U using Tapatalk -

I was about to flash the device, and I ran into a conflict I have already emailed for a resolution on. The Silk screen on the FG99 says "3.3v" AVRdude says use "5v". I really don't wanna create magic smoke from this project. Would using the 5v as AVRdude suggests harm any of the components? We shall see or if you know please respond so I can have a wonderful weekend with this lol.
