    ed1960, instead of pasting the error codes, it might help if you just send us a link to you sketch. That way everyone can check it out, look at the issues, and try to suggest a solution

    Sadly this example is not working at all. It does not compile. I left the error message below.

    It seems it mainly has to do with using the 'send' constructor rather than the 'write' constructor. Also it seems to have problems with the backlight constructor as in: no known conversion from 'int' to 't_backlighPol' for 3rd argument
