Returns the current digitized analog level of the selected ADC channel.
Analog voltage reading from ADC0 resp. ADC_PIN3 isn’t advised
(it is a bit noisy) but supported. Use it at your own risk.
Parameters
channel (int) – Mandatory “channel” number that have to read and can
only be a well known number of: ADC0 resp. ADC_PIN3,
ADC1 resp. ADC_PIN2, or ADC2 resp. ADC_TEMP_SENS
Returns
Digitized analog level on given “channel” and can only be
a value between: 0…1024
