Introduction
This example uses the ECAP in APWM mode to generate a PWM signal.
The example does the below
- Configures ECAP in APWM mode and configures values in period and compare registers using sysconfig.
- Waits for the specified time using the ECAP ISR.
External Connections
Connect OUTPUTXBAR1 output to oscilloscope
AM263X-CC
When using AM263x-CC with TMDSHSECDOCK (HSEC180 controlCARD Baseboard Docking Station)
- Connect HSEC Pin 81 to oscilloscope
AM263X-LP
