Detailed Description

Example: analyse QEP input (simulated by PWM outputs).

This file contains an example on how to use libpruio to analyse pulse trains from a QEP sensor. The sensor signals can either come from a real sensor. Or, to avoid the need of a real sensor, the signals can get simulated by PWM output which is generated by this program. Find a functional description in section qep.
