DIO + PWM – Digital Input Output

A pin object is used to control I/O pins (also known as GPIO - general-purpose input/output).
Pin objects are commonly associated with a physical pin that can drive an output voltage and read input voltages.

In this section we will cover Din and Dout classes.


  • The external hardware has inverse logic which is compensated by this module.
    E.g.: if you set DOUT1 to 1, you will see a high value output.
