CCS/LAUNCHXL-F28379D: SDFM pwm examples for the 28379D, using the launchpad

Richard Tarbell56
Intellectual 335 points

Part Number: LAUNCHXL-F28379D

Tool/software: Code Composer Studio

Looking at the "sdfm_pwm_sync_cpu" example project, and using the 28379D launchpad.  I see that this project has an InitEPwm funciton, but I don't see any part that sets which output pin the PWM is using. 

In this example, I would think that the PWM timer output would go to both the SDFM modules, and an external pin to clock external delta sigma ADCs.  Am I understanding this correctly?

    Richard,

    sdfm_pwm_sync_cpu example isn't configured to clock external sigma delta modulator. PWM is initialized that provide SDSYNC events to synchronize SDFM filters. But, it is true that you can configure one of the PWMs to clock the SD-modulator like you said.
