The problem for me is that I can't find any working code using this library. I'm new to arduino and usual look for working code to help me get started.
Does nayone have any working code using this library ?
There is no such thing as 'the serLCD library' since there is no standard for serial communications with the inherently parallel LCD controller.
Each serial implementation is typically different from the next and therefore requires it's own library. In order to get any kind of useful advice you will have to specify which serial adapter you are using and which library you are trying to use drive it.
