Pico3Mod class

Raspberry-Pi Pico based controler for 3 modules DIN case.

The implementation of the class is closely tied to the features included into 3 modules DIN.

The features are used to design the PCB... so the board schematic is closely tied to the Pico3Mod class implementation.

Features

Methods

__init__()

Constructor of the Pico3Mod class, specialized version of the PicoControler for the 3 modules DIN case. Pico3Mod inherits from PicoControler and DinControler. As a consequence, Pico3Mod also inherits from the methods and properties of the both ancestor.

The constructor will creates the objects & resources specific to the Pico3Mod board. har PicoControler creator is aware of the various Pin used for the I2C bus, Status pin, RUN_APP pin, etc. Le PicoControler can create the various instance accordingly.

def __init__( self, BackplaneClass ):

• BackplaneClass : Class of the backplane to be associated with the controler (eg: TwoRelay3Mod).
