After purchase of the display, installation of software, and connection to arduino uno according to manual.
I have the following problem.
Ex.1 print text (0,0, ‘OXO’, …) Normally the word OXO should appear above the top left.
Unfortunately the machine decides otherwise, see photo 1.
Ex.2 write pixel (0,0, … … normal led far left above
that doesn’t work either, see photo 2.
Error in program ?? Doubtfull as the demo programs have the same effect
Connections ?? 3 x double check
Use separate 5V power supply (a lot of light)
In my humble opinion, the display is made up of 8X (8x8) blocks,
Ex. top left    
Bottom left    
The display makes
Top left    
Bottom lef t    
Error in software? Error in display? Mistake by me?
I hope the problem is more or less clear.
