Analog inputs are referenced as ADC0..ADC7 see GPIO Header. The SUB-20 ADC module features a10-bit successive approximation ADC. The ADC contains a Sample and Hold circuit which ensures that the inputvoltage to the ADC is held at a constant level during conversion.Functionssub_adc_configsub_adc_singlesub_adc_read3.8.1 sub_adc_configSynopsisint sub_adc_config( sub_handle hndl, int flags )Configure SUB-20 ADC module.Parameters· flags - set of below flagsADC_ENABLEADC_REF_VCCADC_REF_2_56Enable ADC module.
