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
Board schematic
Schematic shows how the hardware (buttons, LEDs, buses, ...) are wired to the Pico.

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).
