Hi! I'd like to code a program that simply rotate a stepper motor in a direction and in the opposite using the lpt interface. I know I need to give a square waveform for every step and a square waveform for the direction (or nothing for the opposite direction) but I don't know the timings/frequency for each one and for each step how much the signal should be in high state and low state, can you help me? For example, my motor is 200 step/seconds so the frequency of the step signal should be 0,005 seconds but in this time which is the % of high state and lower state? Thanks in advance!
