Hi all,
I'm new to the world of Arduino and need some help trying to wire-up and run a 20x4 lcd.
I have the a Arduino Duemilanove board with the Atmega 328 chip which i have wired up to a JHD-204A LCD.
I have tried using the default lcddisplay 2x16 sketch and library which works fine displaying 2 lines of code. So i know the lcd physically works
I then tried using the LCD4Bit library and example sketch, but all i get are 2 lines of black squares on the 1st & 3rd line, and the compiler didn't show any problem before upload.
I've searched on the forum and on google and i'm struggling to make it work.
I would be very grateful is someone could send a working LCD4bit (Library & Sketch) that will work with this LCD.
Thanks in advance for the help,
Rich.
