The analog inputs are not instantaneous. You have to start them, then wait a certain amount of time and then read them. The code in adc.c will do that for you and uses a timer to wait. Calls to Get_ADC_Result will simply fetch the result that the library has already captured for you.
The function Get_Analog_value does the start/wait/read operation in-place and takes longer and consumes valuable cycles that could be put to better use doing something else.

How do you allocate the analog inputs with Get_ADC_Result? I found where to set NUM_ADC_CHANNELS, but I haven't found anything about allocating specific inputs. Furthermore, what is used as the argument of Get_ADC_Result?
