Kristian from the YouTube channel Krisseck shared a really cool Raspberry Pi accessory this week, and it's overflowing with nostalgia. After rummaging through some hardware, he came across a shield featuring an refurbished display panel from a Nokia cell phone.
Some of the best Raspberry Pi projects we've come across recycle old hardware, and PCD8544 shields are definitely in that ballpark. Kristian found a Raspberry Pi PCD8544 v2.0 Shield created by a now-defunct developer known as Arduino King. The shield plugs directly into the Pi's GPIO and lets you control a black and white matrix measuring 48 x 48 pixels.
There are other companies that produce Raspberry Pi modules with refurbished Nokia displays, including the Nokia 5110/3310 monochrome LCD from Adafruit. As of writing, Adafruit is out of stock, but the website offers a sign-up form for notification emails.
The biggest hurdle you'll face when using one of these displays is choosing a library. In Kristian's case, ArduinoKing.com is no longer around, and finding the right software to control the screen wasn't easy. Kristian tried a couple of PCD8544 libraries, including one known as Luma and another from Adafruit , with little success. He eventually landed on a script offered by Haoyu , a third-party reseller of the Arduino King shield. The script enabled SPI emulation to get the display to function properly.
If you're going to add a small LCD to your Raspberry Pi, you might as well do it in style, and this is a sure-fire way to add a retro flair to your project. Check out the full video at YouTube and be sure to follow Kristian for more cool projects.
