TMS320F280025C: F280025 High resolution PWM

user4586590

Part Number: TMS320F280025C
Other Parts Discussed in Thread: C2000WARE

Hi,

We are developing using HRPWM of your microcomputer F280025.
Please tell me about the following files of C2000Ware.
\C2000Ware_4_00_00_00\libraries\calibration\hrpwm\f28002x\include\sfo_v8.h

Is 4 in "#define PWM_CH_MAX 4" on line 57 of the above file a fixed number that cannot be changed?
If it cannot be changed, can F28002x have high resolution only for the following PWM?
- PWM1A
- PWM1B
- PWM2A
- PWM2B
- PWM3A
- PWM3B
- PWM4A
- PWM4B

Thank you for your reply.

Hi Tatsuya,

Every controller has a limited number of HRPWM channels. For F280025C, the maximum number of modules that can be used is 4, EPWM1-4 as you rightly pointed out.

You can find the information about the number of HRPWM channels in the device datasheet. For F280025C, you can check here: TMS320F280025 datasheet | TI.com

Thanks,

Aditya
