Controlling a Remote Graphic LCD Over an Ethernet Cable

Over at unstdio.org, there is a great tutorial on how to mount an ST7565 Graphic LCD remotely and control it with an ethernet cable and an Arduino.

I was looking at some pictures of the Makerbot the other day and thought it was cool how they used Ethernet cable for connecting some of the boards together. I was also trying to find something useful to do with these LCD’s I had lying around. Then I came up with the idea of driving the LCD over Ethernet cable.

First, I knew that the ST7565 LCD that I was using is a serial LCD, which means I only need 4 or 5 digital pins to drive the LCD. There are 9 total pins total on the LCD including the backlight. Since there is a backlight GND (LED cathode) and a GND to run the display, I really only 8 connections. This is the number of connections in an Ethernet cable.

This ST7565 graphical display looks great, costs less! The dark gray pixels are visible in daylight, and there’s also a full RGB LED backlight, which you can control with PWM to make any color you can imagine.

Four mounting holes and a blank 11 pin 2mm-pitch labeled breakout on the side – we just soldered some wire to each hole as shown in the photos, its very easy. (The LCDs have no wires soldered in when we ship them)

  1. Just to clarify, it’s not being controlled over Ethernet, but rather over an Ethernet *cable*

  2. You are correct. I had it written in the text, and have now updated the title. Thanks.
