Hey everybody!
My name's Joseph, and I am about to enter my junior year of High School. I recently purchased a tri-color LED matrix controller to help me learn programming with an AVR microcontroller. Because I do not have a full understanding of using the backpack via SPI at the moment, I would like to first try programming the onboard ATmega8 myself in order to display a set pattern on the LEDs to verify that I have learned the architecture of the board. However, before I set out to program, I would first like to understand how to use the 74HC595 first. Do any of you have code snippets or links or suggestions on helping me understand the shift register and how to use it with an AVR? Any help would be greatly appreciated.
PS I will be programming in C
