FRDM-KL25Z ADC OnMeasurementComplete() never gets called

Question asked by Stephen Langstaff on Mar 26, 2015

I'm trying to setup a single channel of an ADC on a FRDM-KL25Z board to use hardware triggering from a PIT (to get periodic samples delivered to an MQX-lite task, but I hope that is not relevant).


I can see my PIT interrupt going off (TU1_OnCounterRestart() is called), but my ADC's OnMeasurementComplete() event is never called.


I have also tried with software triggering instead of the PIT but that does not appear to work either, so I'm pretty sure it's an issue with the ADC.


Any ideas?
