    Looks like they should work·like the Parallax "Parallel" LCDs.

    In this schematic where it says +5, does that mean the 5 v from the stamp or external 5V?

    That means that that pin needs to be connected to a power supply that is regulated a 5 volts. This can be from the stamps power supply or from an external supply if you tie the supply's ground with the stamps.

    According to the datasheet you posted, the LCD nominal power useage is 1.0 mA and a maximum of 2.2mA. So in addition to the methods jcb344 mentioned, you can also power the LCD from a Stamp I/O pin using the HIGH command.

    How should i modify the·code for the 2 X 16 display,·for my 4 X 20 display? Right now it will work ok for 2 lines but when it·tries to go to the·third line it really goes to the fourth.

    thanks,

    Bryan
