How do I trigger automatic conversion on the ADC on the DUE? If this was the uno, I could just do sbi(ADCSRA,ADATE); sbi(ADCSRA,ADSC); but for the due, I seem to have to use adc_configure_trigger(ADC, ADC_TRIG_SW, 0); Though I am not seeing an auto trigger option, only software/external triggers. Will it just know to start conversion once it sees data coming through?

  • Adc has register ADC_MR (adc mode register) and also flag FREERUN... Commented Mar 22, 2022 at 20:23
  • so would setting adc_configure_trigger(ADC, ADC_MR, 1); set up automatic trigger? Commented Mar 28, 2022 at 12:08
  • I'm not sure, maybe. Or maybe adc_configure_trigger(ADC, ADC_TRIG_SW, ADC_MR_FREERUN_ON); Commented Mar 28, 2022 at 12:12
