AM263P4-Q1: ePWM Configuration

Kodari Rajkumar

Part Number: AM263P4-Q1

I have gone through the ePWM_Updown_aq example from mcu_sdk.

I did n't understand ePWM2 have different CMPA values. Generally, ePWM0, ePWM1 and ePWM2 moduels phase shifted by 120 degrees but here ePWM2 only phase shifted. Please explain why and how we can configured for different TBPRD (EX: 5000)

Thank you!

Hi,

The example used has independent modulation for ePWM0, ePWM1 and ePWM2. Using this example, one can change the CMPA value dynamically. This does not show case 120 degree phase shift between phases. Please refer to following documents for getting started with PWM module:

1. Enhanced Pulse Width Modulation (ePWM)

2. AM263Px MCU+ SDK: Download, Install and Setup SDK and Tools

3. ePWM Chapter in TRM: AM263Px Sitara Microcontrollers Technical Reference Manual (Rev. D)

Thanks,
