Using a Nokia PCD8544 LCD screen on a Raspberry Pi
Old Nokia LCD screens, once used for playing snake, are now a great source for your DIY projects. They are widely available, cheap, graphical and easy to use thanks to all the PCD8544 libraries available on the Internet. PCD8544 is the name of the chip used to drive these displays.
As long as you get these connections right there isn’t much to worry about. Just double check that. On the below picture you can see how I got the small 1.5mm spaced connectors to something reasonable. You won’t have to do this if you get a pcd8544 on a breakout board.
Now on a virgin raspbian wheezy image these are all the commands (in that sequence) you’ll need to get the lcd working as a status screen. Open a terminal and ssh to your pi (ssh firstname.lastname@example.org with 0.0.0.0 matchin the ip of your pi). Default password for username pi is raspberry. Now from the shell execute these commands on your raspberry. You might have to hit ENTER when apt-get prompts for it.
Now you have the wiringPi library installed from https://projects.drogon.net/raspberry-pi/wiringpi/ Continue with the installation of the PCD8544 library. To simplify the compilation I also moved the sample into the current working directory. You can skip that but you’ll need to check the paths in the cc command then.
