Can I easily rotate a MAX7219 Dot LED matrix 90 degrees?
Posted: Thu Jun 15, 2017 5:29 amI recently started with Arduino and I got my 8x8 dot matrix to work using an adjusted form of Brainy-bits Space Invaders code. However, I stuck my MAX7219 into a breadboard to have it standing upright, but of course the image is then rotated 90 degrees. Is there an easy way to flip it? I tried switching the DIN and CS pins in LedControl because I wasn't too sure what they do, but it has no effect.
