Hi, all, I'm new to Arduino, and could not use the standard library to the Max7219, using a cheap chinese 8x8 led module. I found that library is written by rows, but those modules work by columns, so had to change it to work. Then i added the basic string scroll function and a character font to make life easier... The setChar function was totaly changed to show letters, i think the original is useless...
Dont know if here is the right place for this, sorry if any problem.
