Dear TI,
I had made a Scalar control code for TMS320F28335 where I've used f2833xpwm.h driver files. I have to do the same for TMS320F28379S but I am not able to find any f2837xpwm.h or similar files. Please let me know how to do it.
Hi Pratyush,
The file is located at : C:/ti/c2000/controlSUITE/device_support/F2837xS/v210/F2837xS_headers/include/F2837xS_epwm.h
If you are using, ControlSUITE, I just wanted let you know that controlSUITE is not maintained. All the new devices and bug fixes are done in C2000Ware SDK. So I will recommend you to use C2000Ware SDK for new project. It can be downloaded from here:
https://www.ti.com/tool/C2000WARE
If you are using C2000Ware SDK already, then the file can be found at:
C:/ti/c2000/C2000Ware_4_01_00_00/device_support/f2837xs/headers/include/F2837xS_epwm.h
Thanks & Regards,
Santosh
Hi Santosh,
I am using PWM_INIT_MACRO which is in f2833xpwm.h, such type of file is also there with f2803xpwm.h but no such library file for f28379s. This is the code of f2833xpwm.h. Is anything similar in f28379?

Hi Pratyush,
These MACROS are not available for newer devices. If this is new devices, I will recommend to use latest C2000Ware and it supports SysConfig (GUI based) configuration of all peripherals. Please take a look.
