 .. note::
    Note that any currently supported |I2C| device can be connected to any port of any multiplexer, provided they are declared in "myAutomation.h" with the HAL() macro, with the correct addressing for multiplexer and sub-bus. It is probably easiest to connect all the |I2C| devices to your multiplexers and let |EX-CS| probe for the them and any devices off each sub-bus, so you can use the console output to guide you in creating the HAL() macro declarations for "myAutomation.h".
