zzzzzzzzzzzz from left to right then scrolling the message from right to left.It worked for me perfect,beyond my expectation.The only problem that i encountered was that when i sent more than 30 characters the scrolling started becoming very slow but up to 15 or so characters is ok.I used 4 max7219s which i ordered them from Ebay and it took only 3 weeks to arrive from China.You are so great thank you very much again ,God Bless you.
