i finally got it working..thank you anyways...had to make sum changes in the code..i wonder if i could extend it to 8 matrices..but i dont think its possible..
I am having this exact same problem, trying to run the "quick brown fox" sketch as found here:
(tried posting the sketch, but it exceeded the character limit)
on 5 daisy-chained MAX7219-driven 8x8 LED arrays. The text starts to work & scrolls fine from right to left, up until the 5th LED Array, which doesn't do anything. I've tested the setup using the LedControl example sketch LCDemoCascadedDevices & it works just fine with that, all arrays functioning as they should. Any ideas why the quick brown fox sketch won't spread across all 5 arrays?
