Hi!
Been playing around with my new “Santa scope” pretty good I think for the money! Anyway – the attached screen shot is a trace of the output pulse from two of the four pins driving a stepper motor, (via a L293D), from a 28X2, pins C.5 and C.7. Would you expect to see double pulses on pin C.7, when the other three pins only have a single pulse per cycle? The traces are taken simultaneously. Using ‘westaus55's’ code to do half stepping to drive the motor.
