* On each call to the ISR one sensor is Sampled and

* the next sensor is Prepared.
|
||||
* One sensor is sampled on every other call of the ISR.
|
||||
* Each sensor is read 16 (OVERSAMPLENR) times, taking the average.
|
||||
*
|
||||
* Sensors are read 16 (OVERSAMPLENR) times and the
|
||||
* final reading takes the average.
|
||||
* On each Prepare pass, ADC is started for a sensor pin.
|
||||
* On the next pass, the ADC value is read and accumulated.
|
||||
*
|
||||
* Extra do-nothing passes may exist when there are
|
||||
* only a few sensors. This is set by MIN_ADC_ISR_LOOPS.
|
||||
*
|
||||
* The timing of this ISR gives ADCs 0.9765ms to charge up.
|
||||
* This gives each ADC 0.9765ms to charge up.
