How to write to register for TI DSPs?

I would like to change (i.e., overwrite) the register values (the whole register or single bit) during the code execution. For example, change F28379D ePWM ramp direction or shift the ramp.

How can I write to register in Simulink? I have tried using a Memory Copy block, but I couldn't make it work.

For example, if I want to change the switching frequency: EPwm2Regs.TBPRD or any other register or bit.

Hi Mike,

As explained on the following page:

https://www.mathworks.com/matlabcentral/answers/1861853-using-a-memory-copy-block-to-read-write-a-single-bit-gives-an-error-and-workaround-not-working

You need to use the Memory Copy block with code symbol and the .all notation.

For example: &EPwm2Regs.TBPRD.all

This will work,

I hope it helps,

Thanks,

Antonin.
