OMAP-L138: Where is output EPWM0 on OMAPL L138 LCDK?

Part Number: OMAP-L138


Hi,

Where is output EPWM0 on OMAPL L138 LCDK? According to the schematics, I know that EPWM1A and EPWM1B are located at Pins, J15.40 and J15.44, respectively. However, I cannot find the EPWM0 outputs. Where are they located? I need to generate two PWM signals.

Thank you :)

    Hi Sajad,

    I've forwarded this to the schematics design experts. Their feedback should be posted here.

    Answer for future visitors:
    By looking at the schematics, you can see that EPWM0 is muxed with SPI. So, you need to modify the board, by removing some resistors. After doing those modifications, you may get the output of EPWM0 from pin J15.25.
    These kind of modifications are explained in detail in one of my old questions. Search for EPWM in my profile, if you need.
