Hi TI Experts,

I am using MCu-Plus-SDK8.03.01.05.

I want to use 2 pwm channels in phase shift mode.

can i refer any example which demonstrates this using MCU-PLUS-SDK ?

Hi Bikash,

There isn't a EPWM phase shift example in the SDK.

I created one from the EPWM HR duty cycle example: https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/08_03_01_06/exports/docs/api_guide_am263x/EXAMPLES_DRIVERS_EPWM_HR_DUTY_CYCLE.html

Changed EPWM9 to EPWM0
Added EPWM1
Added EPWM SYNCO on TBCTR=0
Added EPWM SYNCI on EPWM0 SYNCO
- Enable Phase Shift Load
- Phase Shift Value=8333

Please review example.syscfg for details on the updates.

I've attached the CCS project below.

Regards,
Frank

Hi Frank,

Thank you for the example. I can see the phase shift on the EPWM1 channels with the example project that you have shared.

Another question, In the SYSCONFIG I can see many configuration parameters available for the EPWM configurations, is there any document available which explains the significance of the configuration parameters?

Hi Bikash,

If you hover over a parameters in Sysconfig, a pop-up window provides some information about the parameter.

You can also consult the AM263x TRM here:
