This class collects voltage signals.

Constructor

misc.ADC

class misc.ADC()

Example:

from misc import ADC
adc = ADC()

Methods

ADC.open

ADC.open()

This method initializes ADC.

Return Value:

0 - Successful execution

-1 - Failed execution

ADC.read

ADC.read(ADCn)

This method reads voltage values of a specified channel. Unit: mV .

Parameter:

• ADCn - Integer type. ADC channel. Click here to learn more for supported channels and corresponding pins.

Return Value:

If successful, a specified channel voltage value is returned.

-1 - Failed execution.

Example:

>>>adc.read(ADC.ADC0)  # Reads voltage value of ADC0
613
>>>adc.read(ADC.ADC1)  # Reads voltage value of ADC1
605
