CCS/TMS320F28069F: Missing PWMDAC output

Nicholas Stephens

Part Number: TMS320F28069F
Other Parts Discussed in Thread: MOTORWARE

Tool/software: Code Composer Studio

I'm a bit new to the CCS and motorware environment so please bare with me. I have GPIOs 6, 8, and 10 set to ePWM4A, ePWM5A, and ePWM6A respectively. I'd like to use these signals with the PWMDAC and view them on a scope. I think I have everything hooked up correctly but I don't seem to have any signal on GPIO 8/ePWM5A (I can see signal on both 6 and 10 no problem). Sorry I know this is a bit vague but any thoughts?

    What power inverter board are you using? What lab are you testing? What signals are connected to the PWMDAC? Please help to provide more detailed information that can help to solve the problem for you. Thanks.
