Look at the ADC modules and their use in various demo apps, e.g., Sense. You'll need to rummage around in the platform directories to see the actual DemoSensor implementation. If all you need to do is sample an analog input it should be a straight-forward swap of ADCC for DemoSensor in the config and then using getData() & dataReady() in your code.
