A while back I posted a video showing how to control 8x8 dot matrix without any aditional drivers and libraries.
I promised a follow up video which would show how to control those matrixes with MAX7219 Driver And here it is.
It shows how to use MAX7219 to control the matrix as well as compares the results with the ones from the previous video.
The code and a list of components can be found here:
