Hi Marco! I've been reading all the post and coments and i cant solve my problem with the orientation of my matrix.
I have 5 8x8 matrix, I made the matrixs and the modules with max7219. But when i connect and load the code, the words appears rotated 90°. So is scrolling down one by one matrix. I now that the orientation is the incorrect, but i already make the matrix that way and i cant make another or fix it (320 5mm leds, solder one by one ._.)
Is there a way I can rotate the scrolling 90°?
Regards!
PD: Sorry my english, im spanish.
