Thank you for your code and APP, I will create a 3D shell, and I will transfer it to the stl format to put it into the printer and assemble it together

This is a great project. Thank You. I am a bit new to working with the MAX7219 and have four of the MAX7219's connected directly together in a group. The problem I have is that I need to rotate the message 90 deg. The message is correct but not scrolling across the screen. Its is segmented vertically. Any help or comment appreciated.
