    Hi. Something else lets me believe that its more probable to be code problem rather than hardware. When I tried it with the other LCD library but using internal oscillator (4 mhz input) it did work properly with multiple line outputs. But with this code it outputs some garbage. Will have to check datasheet again for the oscillator settings.

    LATBbits did the black squares trick. However some of the text on the LCD is garbage. for example http://www.electrosome.com looks like elec7roume.6m.

    This is still frequency problem?

     

    thanks

    Hi, thanks for the answer. I did first run a LED test, and it works fine, perhaps a bit faster than expected so I also suspect that it is probably oscillator settings, but I can’t find whats wrong in config.h. I did set FOSC = HS in order to use external crystal. Did I miss something ?

    Thanks

    Yes, as I said in the first post, it works with another library.
