    ATMega32 is an AVR chip. So wrong forum.

    But why would a ATMega32 chip be limited to 5ms delays?

    And how is 5ms relating to 60rpm? The stepper motor having 200 steps? So you now need to be able to step 200000 steps / second? Before you spend too much time wanting 1000 rpm - is that a supported speed for the stepper motor?
