TMS320F280025: Example code about using T1/T2 event to control Action Qualifier

Julia Li

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE

Hi Champs,

Is there any example codes to show how to use T1/T2 event to control Action Qualifier? And how to set ePWM as source of T1/T2 and how to use T1/T2 event as sync event?

I can't find the corresponding example in C2000ware. Do you know any code that can be used for reference?

Thanks in advance!

Hi Julia,

We do have an example 'epwm_ex12_monoshot_mode' available with C2000Ware which demonstrates the T1 event sync use case and its configuration to control Action Qualifier.

Please find below a snippet from the example:

    //
    // Set PWM output as HIGH on T1 event
    //
    EPWM_setActionQualifierAction(myEPWM1_BASE,
                                  EPWM_AQ_OUTPUT_A,
                                  EPWM_AQ_OUTPUT_HIGH,
                                  EPWM_AQ_OUTPUT_ON_T1_COUNT_UP);

    //
    // Configure T1 trigger source as PWM SYNC signal
    //
    EPWM_setActionQualifierT1TriggerSource(myEPWM1_BASE,
                                           EPWM_AQ_TRIGGER_EVENT_TRIG_EPWM_SYNCIN);

Thanks,

Aditya

Hi Julia,

Since we haven't heard back from you on this query, I believe you've been able to resolve the issue. I am marking this thread as resolved.
