Example Description

This example configures EPWM0, EPWM1, EPWM2 to produce signal of desired frequency and duty. It also configures phase between the configured modules.

Signal of 10kHz with duty of 0.5 is configured on ePWMxA & ePWMxB with ePWMxB inverted. Also, phase of 120 degree is configured between EPWM0 to EPWM2 (EPWM2 to EPWM4 in case of AM261x-LP) signals.

During the test, monitor EPWM0, EPWM1, and/or EPWM2 (EPWM2, EPWM3 and/or EPWM4 in case of AM261x-LP) outputs on an oscilloscope.
