Hello,
I am trying to program my homemade 8x8 LED matrix, with MAX7219ewg chip and i don't know what code our library to use. I have tried MD_721xx and LedControl libraries, but unfortunetely it's not working... So the question is: how should I write my code, our what library should I use?


This is how, I have connected my matrix, this is just identical copy of my circuit.

You have some code you didn't post. It does something that you didn't describe. You want it to do something that you didn't describe.

You can't get from point A to point B if you haven't a clue where point A or B are.
