Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hello,

I want to change EPwm10Regs.HRPCTL.PWMSYNCSEL using DriverLib but:

1) There's no API in epwm.h which accesses HRPCTL.

2) The ASSERT macro in HRPWM_setSyncPulseSource() excludes ePWM 9 to ePWM12 because these are not HRPWMs.

Please can you update epwm.h to allow access to HRPCTL since this register is applicable for all ePWMs regardless of HR or not.

Hi Kier,

Thank you for your comments. Yes, this is something we recently changed and will be in included in the upcoming C2000Ware release.

You can make the following changes for now:

1) In epwm.h add the following "#include "hrpwm.h" and,

//*****************************************************************************
//
// Functions APIs shared with HRPWM module
//
//*****************************************************************************

//
// Period Control related API
//
#define EPWM_setSyncPulseSource                 HRPWM_setSyncPulseSource

Best Regards,

Marlyn

Hi Marlyn,

Thanks for the update and workaround but it doesn't work for ePWM9 to 12 due to point 2).

But no matter, I've created my own EPWM_setSyncPulseSource() in my application code for now.

Kier.

Hi Kier,

Thank you for your patience. Aditya Dholakia can Kier's 2nd point also be addressed within driverlib files?

Best Regards,

Marlyn
