Hello,
I'm trying to get the ADC working on the CC2640, following the steps described here: 
However, I cannot get it to work, as the ADC FIFO remains empty. This is my setup code:
AUXWUCClockEnable(AUX_WUC_SOC_CLOCK | AUX_WUC_ADC_CLOCK);
AUXADCSelectInput(ADC_COMPB_IN_AUXIO7);
AUXADCEnableSync(AUXADC_REF_FIXED, AUXADC_SAMPLE_TIME_2P7_US, AUXADC_TRIGGER_MANUAL);
Power_setConstraint(Power_SB_DISALLOW);
AUXADCGenManualTrigger();
I then periodically execute this:
uint32_t fifo_status = AUXADCGetFifoStatus();
AUXADCGenManualTrigger();
But fifo_status is always 1, that is, AUXADC_FIFO_EMPTY_M. Why is this happening? IOID_23 (AUXIO7) is configured as follows: PIN_INPUT_DIS | PIN_GPIO_OUTPUT_DIS.
Thanks!
