Re: [oopic] Program Resetting Upon Completion of Stepper Motor Script

When connecting any electromechanical devices (relays, motors etc.) to a circuit it is always a good bet that they will generate spikes and noise back into the circuit driving them. The best bet is to use a separate power supply. You will still have noise feeding back on the control pin to the microprocessor. It is best to make sure that you use the proper bypass capacitors to help filter the noise out. I believe most relay circuits also employ reverse diodes to shunt any reverse spike voltages.

Take a look at the following article for a good explanation of this.

Hop this is of some help, Wayne..

the ooPIC resets, which turns the power off allowing the ooPIC to turn
back on. Are you running the motor on the same power supply as the
ooPIC logic?
