Hello Everyone, I've had something of a vision, and I don't think it was spoiled food :-) And I'd like some feedback on it. Bear with me, it requires a bit of set up.

(...) Glad you brought that up. I would, of course, take code for the miniboard, fingerboard, etc. I use the F1 board myself. There are enough people out there who like to port things, anyway.

I can offer that in my C++ course I learned that in order to pass a variable name into the array size declaration, it must be a const int type. Don't know if that's true for Ic, but if it is, you'll be able to keep your cycle_length variable. (...) (25 years ago, 16-Jul-99, to lugnet.robotics.handyboard)

I just got the stepper rountine working in my board this weekend. There were some problems initially. I had to replace the cycle_length with the actual number (4).
