Thanks for the reply! Yeah, I did select the correct chip on the matrix (tried a few different configurations, too). I'm still having trouble with the test code, I deleted all the DEBUGPRINT lines, but now I have this error: "Documents/Arduino/libraries/myfont/myfont.h:9: error: expected initializer before 'myfont'"
I wish I knew what that meant, should I edit the myfont document somehow?
