In T1 sensorboards/micasb/PhotoTemp.nc the actual ADC is configured thus: PhotoTempM.InternalPhotoADC -> ADCC.ADC[TOS_ADC_PHOTO_PORT]; It's probably been further obfuscated in T2, but the basic idea is that TOS_ADC_PHOTO_PORT is the ADC channel number to which the photo sensor is attached. To read that ADC one then calls InternalPhotoADC.getData() and gets the result when InternalPhotoADC.dataReady() fires. All the rest of the code and component config upon module config files is to add various kinds of "features". Specifically the sensors need to have their power turned on and off. If all you need is to read the ADC you can just use a config like the above line.
