Private variable not initialized

[jamesarm97]

I tried to use this library and was getting i2c errors wrong length. It looks like the i2cwidth private var needs to be initialized to 2 for the TCA6416A since it is expecting to read two bytes. That fixed it for me.

I am getting the same i2c wrong length error but I don't understand how to make the modifications you suggest, can you explain a bit more? i cant get the inputs to work just the outputs seems to work
