Hey crossroads.....how ya been.....so I'm working on a new 32x8, my first one worked ok, all the matrices showed the same letter as it scrolled each one individually ...that was with my mega2560......but now I've got a 16x8 scrolling perfect.....I did just rotate the matrices physically....however I add on two more to make it 32x8 and the 3and 4 matrix are blank while 1and 2 scroll across.....I have them cascaded, all caps and resistors in place.....I'm using a nano this time.......ill paste my code in the morning....
