Title: 16x2 LCD Wire diagram?
Post by: sparticvs on August 20, 2012, 01:33:23 pm

I noticed in the video (and picture on the page) that there was a configuration done for the 16x2 LCD. I am interested in the wire diagram for that, as I have one of those laying around that I have been wanting to incorporate in my next computer build.  Thanks!

if the LCD has a typical controller then it wires into the board like any other serial device (pins 0 and 2, I think, plus pin 1 if you want to get data back from the lcd)

I don\'t think I know what is meant by a \"typical controller\". The LCD\'s that I have used with my arduino uno require 4 data pins, and 2 control pins (one for switching registers and the other for switching between read and write mode). Plus one for controlling the backlight if desired. So when you say three pins, are you using a special type of LCD, or a special LCD library, or is the typical LCD wiring overly complex? Here\'s a link to the arduino tutorial I used as a reference: http://arduino.cc/en/Tutorial/LiquidCrystal

I see that there is now a digispark  i2c LCD shield kit. I was unaware of the ic2 type of LCD but I see that it takes only two pins, and there is already a library to support it (http://arduino.cc/playground/Code/LCDi2c). Pretty cool.
