class ADC -- analog to digital conversion

Usage:

import machine

adc = machine.ADC()             # create an ADC object
apin = adc.channel(pin='GP3')   # create an analog pin on GP3
val = apin()                    # read an analog value

class ADCChannel --- read analog values from internal or external sources

ADC channels can be connected to internal points of the MCU or to GPIO pins. ADC channels are created using the ADC.channel method.
