Need help trying to get the Arduino working with the RGB Matrix (with backpack) and an EEPROM chip. Answered
Hi everyone, first question on instructables! I have an Arduino Deumilanove, a Sparkfun RGB Matrix with backpack, and an EEPROM chip (24LC256). I have the Arduino all hooked up to the matrix and have been able to mess around with some basic images and colors, but I have a lot of questions. So far, to display letters I have been setting up sections of code that light up each LED separately. I know there has to be a more efficient way to do this and was wondering how? Also, I have an EEPROM chip that is setup with the Arduino and Matrix but can't figure out how to use it. I have looked at the code for it on the Arduino website and I can't really figure out how it all works. So basically, here's what I want to be able to do: - Store the alphabet in the EEPROM - Be able to recall letters from the EEPROM - Display marquee messages Thanks in advance!
