How do I rotate 180 degrees 4 x MAX7219 with LedControl.h?
It seems like there should be a simple setting like in other libraries but I am not seeing it and can not find a simple solution online. I am asking before I manually change the font.h header file which seems like a long and crazy way to get this done. The 4 MAX7219 came soldered onto a PCB so any hardware manipulation I think is off the table. I would just buy another one but there is no way to tell how these things are wired up so I may just have the same issue. And I bought 2 of these and it seems crazy to throw them away.
