Thanks for the response, one question that has been plauging my current design choice is the isolation of programming pins from their alternate purposes. The tiny45 is only an eight pin device, of which I require six I believe for the programming, and that doesn't leave much for else. How would one go about isolating these pins functions from their alternate tasks? For my project, there will be one stepper motor driven via a L293N, and I think that is going to require at least 4 pins of the tiny45, then another couple for analog inputs to figure when to start and stop driving the stepper...How does one go about keeping these isolated from the programming functions? Other than using jumper pins and having to manually switch shunts each time I want to program?(Although that could work for my purpose, I would like a more robust solution..) Thanks in advance, Jaydag71
