Arduino and HD44780 LCD

Submitted by Carl on Saturday, 20 September 20084 Comments

I’ve just been playing with a new HD44780 4×20 LCD from ebay on the Arduino. As I’m still ‘playing’ I’ve tried to document a kind of breadboard interface for the Arduino to LCD. It should help me to remember how things are setup so I can use it a modular fashion later.

    Hi,

    I have the same hardware and I’m interested in giving your code snippet a go but that link appears to be dead- do you still have it? thanks

    Hi Ken
    You can try, but it does appear Wordpress has broken some of the code http://slog.carlheaton.co.uk/index.php/2008/09/arduino-and-hd44780-lcd-v10/

    Also try http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1144924220/8 (see code by Tomek).

    Ta,
    Carl

    Your breadboard pincount is wrong. You have 0,1,2, and then extras until you get to 10, which should actually be either 11, or something… And you have wasted jumpers on the board.

    Good job I’ve not needed to use this again or I’d of been slapping my head more than I am now. Thanks ‘No’.
