A while ago I bought a 128x64 graphical LCD display from Crystalfontz (link below), and it has now been about 2 years and I have never done anything with it, because I have found absolutely no tutorials or libraries for it whatsoever. It uses a Neotec NT7108 controller, but most of the tutorials for graphical LCD displays I've seen use the ST7920 controller.
All I need is just a simple Hello World tutorial for it, with a wiring diagram and Arduino source code.
Thank you for your link. This is great, but I was more looking for a complete tutorial (maybe on Instructables or Arduino Project Hub) that included a wiring schematic and source code.
BV3D (youtube) does a good job of wiring and source coding through the Elegoo Starter Kit.
DroneBotWorkShop does an above-and-beyond (youtube and his own web site) of everything Arduino and Beyond!
Arduino's Project Hub has great advanced stuff, but I find the starter projects on Arduino.cc's Project Hub outdated, poorly written, inaccurate and copy/pasted (to include copy/pasted errors... dare I write "plagiarized"?). If you want very in-depth Arduino code, try Anas Kuzechie (youtube - there are two out there, but only one does Arduino). His low-level stuff is brilliant.
If you go there, you will get much less than you deserve. Also, those folks generally pick easy projects that they have basically recycled from somewhere else. So the chances of finding anything there for such an uncommon display is very remote.
