    NL2TTL,

    the LCD should work on Line 1 and Line 2 if you connect only E1 to the PIC and tie E2 to GND.

    for a quick test you could also connect E2 to E1, Line 3 will than be the same as Line 1 and Line 4 the same as Line 2.

    On the link INGVAR has already posted you'll find an example of how to toggle between the two controllers using only one additional pin on the PIC.

    IF the LCD is displaying nothing at all I guess VEE is not set correctly.

    Attached is the Datasheet of the YMS404-01

    Regards

    Ralph
