So, I decided to start an 8x8 LED matrix project using a MAX7219 and PIC18F4550. My issue I've run into is that my the LED matrix I found is a max 2.7 forward voltage drop. The MAX7219 outputs around V+ -1.The minimum amount for V+ is 4V so this will put me near the 2.7V maximum of the matrix...
Hello all,
I'm in the beginning stages of a project and am just learning how to use an Arduino Uno with a MAX7219 driver with an 8x8 LED RGB Matrix.
I'm using someone's source code to just get a basic understanding of how to put all these pieces together and will then modify it as I need to...
