I am working on a led matrix project, and I have had no luck finding code that works for the setup that you have (595's without specialized led driver chips). I am trying to get this project done in 2 days for an event coming up, and I would appreciate it if you posted the code you used or sent it to me directly. I found sample code from Earthshine Design's tutorials, but it does not seem to work and I have quadruple checked the wiring!!!
Please post the code! Thanks. ;D
BTW I already have 20 8x8 matrices and quite a few 595's, but I just dont have the money for 20 Max 7219's!
