TMS570LS0914: TMS570LS0914

Part Number: TMS570LS0914
Other Parts Discussed in Thread: TMS570LC4357

Hi,

I want to use ETPWM module for controller TMS570LS0914

When i am calling this function  etpwmSetCmpA() and set the different duty cycle to check the pwm signals  on ePWM1A and ePWM1B pin and if run the code step by step , i am no able to get any signals on Pins only getting LOW signals on Pins and if i do continue or free running of code that time i am able to get signals on both the Pins ePWM1A and epwm1B(getting duty cycle whatever i have set in code) which is exactly i am expected.

But when same thing i am doing with the other controller which is  TMS570LC43 my code is working as expected.

is there any different between controller ??
