LP-MSPM0L1306: how to use Periodic TIMER's zero event to trigger ADC Single channel single conversion

?? ?

Part Number: LP-MSPM0L1306
Other Parts Discussed in Thread: MSPM0L1306

Tool/software:

I use the example adc12_triggered_by_timer_event_LP_MSPM0L1306_nortos_ticlang, and I modify some config. I want to use Periodic TIMER's zero event to trigger ADC Single channel single conversion, but it did not work. the following is my setup..The ADC interrupt will only work once, and I think it is triggerd by the init function(

DL_ADC12_enableConversions(ADC12_0_INST);). I need your help, thx.

Yes, after a single channel - single conversion the ENC bit is cleared automatically. You must re-enable the ADC using the DL_ADC12_enableConversions() before the next timer zero event occurs. You can do this either in the ADC12 ISR or in your main while loop.
