Question
LPBAM Scenario usage multiple analog watchdogs
I've trying for days to get the LPBAM tool to work. The TempSense example project is similar to what i'm trying to do. I'd like to immediately stop2 on power up and continually sample 3 channels. The first condition i'm waiting for is IN1 > 1100, so i setup a AWD1 no interrupt with a LPTIM period change triggered on rising edge ADC4 AWD1 so i can see it on the scope (no debug in stop2 or at least i haven't figured it out). Then i'd like to switch the analog watchdog to IN2 (haven't been successful reusing AWD1 since i'm done with it nor using AWD2) and here i'm looking for a signal around the midpoint of the ADC (sine wave zero crossing). From what i've read, the watchdog range won't work backwards (trigger inside a range not outside a range) so I set this up as two watchdogs, first going up out of the lower half and then the second coming down out of the upper half (close enough to a zero crossing for me). After these signals have all occurred in that order, i'd like to DMA capture 512 samples of all channels and then wake up to process the data. This all seems possible on paper and would be really powerful if it did, but not apparently in practice. I'm not sure if i need to be clearing watchdog flags somehow and thats why it won't progress to the next trigger or not.
