Heres my latest update:
so I have cascaded them now...data out from 1st max7219 -> data in to next one....and so on for 4 of them to control the 32 x 8 (4 matrices..)
Its a tight enclosure...I fixed numerous issues...
I had the Rset on the 2nd max7219 on pin 17 not 18......fixed that..so the 2nd Matrix is ok now.....I was about to replace the chip too, but I saw that right at the end....
heres my code working in the enclosure... (Attached)
the problem with the LedControl Library is 1.0.1 doesn't support it, even when I exclude SPI...so which IDE version do you have?
The only other thing that is bothering me ..well two things actually...
so the matrices don't scroll across each other, they just all show the same letter as each individual matrix scrolls...
AND The letters are Backwards.....and before you think anything there, I already swapped the wires around thinking it was wired in backwards, but that made it worse.....
