TMS320F28379D: How Can I synchronize two TMS320F28379D to get 24 ePWM?

Tool/software:

Hi,

For my project I will require 24 PWM which I can generate using two TMS320F28379D.

Is there any way synchronize the epWM from both of the TMS320F28379D?

Any help or guide will be appreciated.

    Hi, 

    So to clarify, it sounds like you are trying to synchronize PWMs across devices. One way you can do this is by treating one device as the master/controller and sync the other device to it. This can be done by using device #1's PWM sync-out (which can be brought out to a pin using output XBAR) and route this to device #2 as an external sync source using INPUT XBAR. There are likely similar E2E questions on this explaining how to do so if you are able to peruse the forums as well. Let me know if this sounds feasible for your application.

    Best Regards,

    Allison
