class ADCBlock -- control ADC peripherals

The ADCBlock class provides access to an ADC peripheral which has a number of channels that can be used to sample analog values. It allows finer control over configuration of :ref:`machine.ADC <machine.ADC>` objects, which do the actual sampling.

This class is not always available.

Example usage:

from machine import ADCBlock

block = ADCBlock(id, bits=12)  # create an ADCBlock with 12-bit resolution
adc = block.connect(4, pin)    # connect channel 4 to the given pin
val = adc.read_uv()            # read an analog value
