    Default LCD; silly n00b problem...

    Hi guys, long term lurker first time poster!

    I have a silly problem...

    I have salvaged an old 1x16 lcd from a phone, I am sure it is HD44780 compatible.

    I am using a pic16f628, but when I try the program all I get is this;


    Any ideas?

    TIA

    Hi TIA,
    Looks like it is working, you need to add a contrast control.

    I have a variable resistor for the contrast, all I get is those blocks though...

    This is the code I have;

    PAUSE 1000
    LCDOUT $FE,1
    LCDOUT "Hello World!"
    STOP
    END

    Is that correct?

    TIA - Thanks In Advance.
