    You need to determine if the LCD you have has an on-board controller, or just row and column drivers. If it has an on-board controller, you can most likely drive it directly with a PIC. If you're REALLY lucky it will have an on-board SERIAL port, which makes it real easy.

    Do a Google search on "Serial LCD" to educate yourself as to the differences of the various on-board controllers and serial port versions.

    Have a dedicated PIC wich will drive your LCD by using LCDOUT command. The default schematic is shown in the LCDOUT section of the PBP manual.

    at the end the huge thing should look something like
    Code:
    Start:
        SERIN SerialInput,SerialMode,SerialData
        LCDOUT SerialData
        GOTO start

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Look inside the documentation of PicBasic Pro and read around the LCDOUT-command. There is a drawing to connect "normal" LCDs.
    Seriel LCDs are "anormal".

    Maybe there will be a typenumber on your display. This will help us to find the documentation for you.

    As far as a source goes - crystalfontz offers several. Mouser & Digikey also sell an assortment
