Problems with 8x8 matrix

Projects Programming
1

Hello,
I am trying to program my homemade 8x8 LED matrix, with MAX7219 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.

Three posts all within a span of a couple days on the same project? ? ?

Seriously? ? ?

We already told you what you needed to do. The fact that you ignored it is making me rather angry.
