Mike,
Chuck McManis may have answered your request, but in case you still
want sample code I am attaching an example code that prints to the
HandyBoard display.
(The code forms part of the Handy Board buffalo I had developed).
I had trouble getting the display working as well.
The main problems were:
1. In single line display, the display is to dark to read.
Putting the display in two line, allowed the writing on the
display to be read.
2. You first need to send a 'Display On' code to the display,
before any future writes to the display will work.

| From the driver code I recently sent out: * LCD Connections on the Handyboard * PORTB bit 0 - R/W * PORTB bit 1 - RS (Register Select, 0 = instruction) * PORTC 8 bits of Data * PORTA bit 4 - E clock (...) That is correct, the LCD is NOT memory (...) (27 years ago, 4-May-98, to lugnet.robotics.handyboard)
