CCS/TMS320F28335: Internal Capture of ePWM.

David Bamgboje

Tool/software: Code Composer Studio

Hello,

I am generating 3 phase shifted pwm outputs but I would also like to detect when each pwm is HIGH and use that in a subsequent control law. Please is there a module that can do that or what are my options? The eCAP module will require me to send the pwm output back into gpio and since I am generating the PWM I feel it should be possible to also access it right inside the controller.

I would also appreciate helpful reference materials.

Thanks.

David.

Hi David,

eCAP module would be most relevant in your case. Internal access of ePWM for eCAP module seems doubtful apart from synchronization. You'll have to do an external hardware connection.

Thanks Gautam.

I have read about the module and I have gone through some examples. I am currently working on implementing it.

If I need any clarifications, I will definitely revert.

Kind regards.

David.
