TMS320F28335: No Output

Part Number: TMS320F28335
Other Parts Discussed in Thread: CONTROLSUITE

Hi Team, seeking some help if you have some idea or information about this inquiry.

Using the F28335 and the digital motor control application library in control suite the program compiles without error but then when I try to check the output on a scope, there is nothing there
i realize that the values in the counter compare registers are not being updated for all the ePWM channels.
Thank you.

    As you mentioned above, check if the values of EPWM CMP register are updated, and PWM duty values, pwm1.MfuncC1/2/3 are updated as well. 

    You may try to refer the example project in controlSUITE as below which is based on F2833x for motor control.
