TMS320F28388D: Missing implementation of EPWM_setSyncOutPulseMode in F2838x version of driverlib

Marvn Arcangel
Genius 16450 points

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Hi Experts,

the F2838x veriosn of the driverlib has this entry:

./driverlib/f2838x/driverlib/hrpwm.h:229:#define HRPWM_setSyncOutPulseMode                EPWM_setSyncOutPulseMode

However, unlike F28379xD, there is no implementation of EPWM_setSyncOutPulseMode().

Here is the grep results:

~/opt/ti/c2000/C2000Ware_6_00_00_00
$ grep EPWM_setSyncOutPulseMode --include=*.h -nIr .

    Hi Marvin

    Yes, you are correct. The EPWM_setSyncOutPulseMode is not present for F2838x since SYNCOSEL bit (In TBCTL register) was removed. Instead, they have added 

    SYNCOUTEN register which has the same functionality and there is a separate API (EPWM_enableSyncOutPulseSource) in the driverlib to configure SYNCOUTEN.
    So, the HRPWM_setSyncOutPulseMode should be mapped to EPWM_enableSyncOutPulseSource API as below:
    #define HRPWM_setSyncOutPulseMode                EPWM_enableSyncOutPulseSource
