TMS320F28379D: ADC interrupt is not working with other 2 EPWM interrupts.

Part Number: TMS320F28379D

I am using 3 interrupts in my program.

1. ADC1A interrupt ( interrupt freq-10kHz) triggered by epwm9

2. Epwm1 interrupt (interrupt freq-585Hz)

3. Epwm4 interrupt (interrupt freq-750 Hz)

Adc interrupt is not working with other 2 EPWM interrupts but if i am using only adc interrupt and triggering with epwm1 its working.suggest me any solution for this.

Hello,

Can you get the ADC interrupt to be triggered by ePWM9 at all (with or without the other ePWM modules enabled)? Can you check that you've configured TRIGSEL correctly? If you can share some of your ADC and EPWM configuration code that might help me narrow down what the issue is.

Thanks,
Whitney

Thanks Whitney

EPWM9 is working fine with ADC interrupt, only mistake was we had put directly hex value from ref manual in the TRIGSEL reg but its actually need to put decimal values in this reg.

Did that resolve your issue, or are you still having trouble with the ADC interrupt when you enable the two ePWM interrupts?

Hi Whitney

Yes, issue resolved. ADC interrupt is working fine with two another EPWM interrupt.
Thanks for your response.
