Hi everybody!
I have a problem in ePWM trip function in 28377D DSP.
I want to trip the ePWM 1,2...11,12 module when ADC PPB(Post-Processing Block) limit detection event(ADCEVTX) occures.
so, I did setup ADC PPB module, ePWM Xbar, ePWM DC module(DCBEVT1) and ePWM OST(One-Shot) & TripZone module and do the experiment (trip test)
(ADC SOC is sync with 10kHz ePWM signal)
When i insert voltage at ADC A input pin, there is only few tripped ePWM module and the others is still working(PWM out)
Bellow is test result.
As upper figure, ADC PPB TRIP State is latched 1. but any of ePWM DC module is not latched this ADCAEVT1 trip signal.
whenever i do the test, result is always same!
if i change the ePWM Xbar setting(change from ePWMXbar trip4 to trip7), i got a little bit of changed results, but a few ePWM module is still working.
What should i do for all ePWM module tripped?
