TMS320F28377D: Synchronizing EPWM modules with different sources

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi,

I'm working on a application where my EPWM modules are working at different frequencies st

Freq(EPWM1)=Freq(EPWM2)

Freq(EPWM3)=Freq(EPWM4)

Freq(EPWM5)=Freq(EPWM6)

but 

Freq(EPWM1)≠Freq(EPWM3)≠Freq(EPWM5)

Also, EPWM 1 and 2 have to be synchronized, similarly EPWM 3 and 4 have to be synchronized and EPWM 5 and 6 have to be synchronized. I'm not sure how to write a code for this. TI has a block diagram for something similar in TRM.

    Hello,

    We have an EPWM synchronization example available for you to use as a reference or starting point located in C2000Ware here: C:\ti\c2000\C2000Ware_5_02_00_00\driverlib\f2837xd\examples\cpu1\epwm\epwm_ex3_synchronization

    Please take a look at this to see if it helps you understand the software. If you have any more specific questions, please let me know.

    Best Regards,

    Allison
