Hello, i have made a one color 8x8 LED matrix and am running it with a MAX7219 and Arduino UNO. I want to add a microphone to make a real time spectrum analyzer with it. I have found many on the web that use a PC with processing but I want a all-in-one. The closest one i found was an Adafruit page http://learn.adafruit.com/piccolo
. It gives code that uses a different LED driver and a 2 color matrix. I would like code for a single color LED 8x8 matrix and uses the MAX7219. Can someone help or give me tips? Is this easy? Did someone already write a sketch for this setup that can share it?
The adafruit version code can be downloaded at https://github.com/adafruit/piccolo/archive/master.zip
Thank you for help and or tips.
