Detailed Description

Handles configuration and initialisation of the analogue to digital converter unit, plus starting conversions and post-handling the conversion results.

We use DMA channel 0 to move results from the ADC conversion memory into a SampleBuffer once the conversion has completed, such that the CPU need only request the beginning of a conversion run and some time later, the results will appear in the SampleBuffer that the CPU specified.
