I am very new to this programing stuff (I have had a little java), but I have to use a Led display for a project. I heard that arduino was the best way to control Leds, so I bought an arduino,
and I have wired it to a Max7219 (as i heard this was the easiest way to make this work).
I have done the initial test (blinking Led) and it worked fine, so now I would like to test my Led matrix. I wired my Led matrix according to:
http://www.arduino.cc/playground/Main/MAX72XXHardware
I have all of the starting Libraries, but I don't seem to have the one that everyone on the forms is talking about and using (LedControl.h).
I have read the article on it, but I do not understand it.
http://www.arduino.cc/playground/Main/LedControl
Basically, I would like to know the easiest way to make a basic program for my Led matrix. Do I need to make a library called LedControl, or can I download it somewhere?
Maybe I am completely missing the point of the LedControl article, as I said earlier, I don't understand it. Any insight to the best way to make this work would be greatly appreciated.
(For those of you that are wondering, my setup is as follows:
Arduino board
Max 7219
8x8 (2 color) Led Matrix
22k resistor (for the power going to the max 7219)
And the proper capacitors.
I HAVE had my Led matrix light up once, but I'm not exactly sure how. I am not 100% sure that I wired the max7219 to the Led Matrix correctly, so I would really appreciate it if someone would explain how to test it. Thanks.)
