Detailed Description

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.

)

[inline]

If a kernel is present, preempt until convertion is complete, otherwise a busy wait on ADCS bit is done.
