Also Trying to get Display Board Working
I am also struggling to get the same Hardware working. It looked the same with the lighted up screen but there was no display when correctly connected and running Marlin software with what I thought was correct config set up.
Wrote Sketch Just to Test Board (Attached)
What I managed to do today was to write, with much assistance from Anthopric Claude, a test program and this took my display from the lighted up but blank screen to the Lighted up and showing text.shown in the picture.
This was at least reassuring as it proved the screen is working.
I then tried to add code to test the SD card reader, the control knob etc but at the moment they do not work.
Next Look more info Connections
My next task is to understand better the IO between the Arduino and the Displayboard which has alluded me so far - i.e. what Arduino Pin is connected where. I imagine this info must be somewhere.
That info is needed to input correct pin numbers into the attached test program.
What is Attached
The attached pic is my hardware with the display showing the result of running the attached sketch using the Arduino IDE.
Will Try that Other IDE
I have seen the comment abouve about using a different IDE and I will try that.
Strategy and Objectives
I figure that its best to get hardware for my Rebuild of a MonoPrice Select Mini V2 controlled by the pictured Hardware will be easier , bit at a time once the display card is working.
