Hi, after long reading on the forum I have to ask a question. I couldn't find the answer here.
You should have noticed that we almost always require a photograph and a sketch.
We need a photograph that allows us to unambiguously follow each wire from the display to the Arduino. Since your display is working you probably have your power and control signals connected properly and you most likely have your data lines connected correctly as well, but we really have to check everything.
So this points to the program. Now we need a copy and paste version of the actual sketch that you are using to produce the result in the photograph, not a reference to the sketch that you think you are using.
