ADC hardware-specific implementation.
This ADC module should be use both whit kernel or none. If you are using a kernel, the adc drive does not wait the finish of conversion but use a singal every time a required conversion are ended. This signal wake up a process that return a result of conversion. Otherwise, if you not use a kernl, this module wait whit a loop the finishing of conversion.

uint16_t adc_hw_read | ( | void | ) |
Start an ADC convertion.
If a kernel is present, preempt until convertion is complete, otherwise a busy wait on ADC_DRDY bit is done.

Select mux channel ch.
