I am a bloody beginner everything regarding coding. I'm currently trying to hook up an 8x8 dot matrix max 7219 display to my raspberry pi zero WH.
I've installed many different dot matrix drivers but only one worked (code-wise). But if I try to run a test file, that is provided by the library, nothing happens. maybe one of you encountered the same problem or might as well help me with my problem.
Re: 8x8 Dot matrix max7219 doesnt work
can you enumerate the "drivers" that you used?
can you share with us the code?
anything else you dont want to tell us?

What language? What library?
Richard Hull's Luma stuff on Github works as long as your MAX7219 is wired correctly. Mine is on SPI0.0 (CE0)
