TMS570LS1227: Enhanced Pulse Width Modulation (ePWM) module

Sebastian Mazur

Part Number: TMS570LS1227
Other Parts Discussed in Thread: HALCOGEN

Tool/software:

Hi,

I need to develop an application to test the Enhanced Pulse Width Modulation (ePWM) module under TMS570LS12x Hercules Development Kit (HDK).
Is it possible to use LED D5 to observe the changes made by the PWM? By default, LED D5 is controlled by NHET signals (NHET1[0]).
Can the Pin Multiplexing (PinMux) module be used to reassign this pin to EPWM2B and use the LED D5?
Do you have any example code that demonstrates (ePWM) functionality?

Hi Sebastian,

My apologies for the delayed response:

Yes, you can do that!

I mean you can use LED D5 to test ePWM. You can configure something like below in pinmux, if you are using HALCoGen.
