Turn an old PC into a multi-channel pulse generator, for PWM/servo/stepper


Posted on Jan 19, 2013

PulsePar turns a PC into a multi-channel pulse generator utilizing the parallel port. The period, duty and phase of each channel are adjustable so as to be used in PWM systems as well as in testing servo and stepper (stepping) motors. If you have an old PC, boot it by dos to run PulsePar and control it by SeriCon on your GUI PC through serial port.
