my hardware is a Macbook Air, running Yosemite, the Arduino IDE 1.6.0
I have a Sparkfun LED Matrix that needs updated firmware. The firmware is there on the page, but it’s a hex file I think. I am very familiar with Arduino sketches, and I’ve even used an UNO to burn the boot loader on Atmega328P’s and Atmega328P-AU chips. I would know how to connect my UNO to the ICSP and load a sketch to this, as I see it has an Atmega328P-AU chip, but I don’t know what I’m looking at when I open the firmware file. Here is the firmware folder. Can someone tell me how to get a sketch out of this or how to use my UNO to load it onto the matrix board? thanks so much.
