/* The goal of this program is to show the basic connections and workings of Adafruits 32x16 RGB LED matrix board (http://www.adafruit.com/products/420), also sold on other places, for instance http://www.ebay.com/itm/PH6-RGB-Full-Color-LED-16-32-Dot-Matrix-Display-Module-/310303408628?pt=LH_DefaultDomain_0&hash=item483f8641f4 (no affiliation with either of them). This program is not intended to be highly optimized or a guideline in C programming in any way (more of the opposite actually). To have more than 7 colors on this thing, you need to implement software PWM of some sort. I have obviously not done that, but if YOU do, please let me know! Adafruit have a wicked demo program for an arduino - www.youtube.com/watch?v=lY-flFEfsHo There are probably lots of ways to make this perform better, perhaps by using Neal Hormans port of the Adafruit_GFX library (http://mbed.org/users/nkhorman/code/Adafruit_GFX/). No error checking or out-of-bounds checking is done. Use at your own peril. For more detailed information on the driver chip, see http://www.bjtopspace.com/ziliao/CYT62726.pdf Although the chips on my board says jx15020, I've been informed that they are equvivalent to the CYT62726, and so far it's a match. Feel free to use all or parts of this work. If you choose to do so, I would appreciate a small mentioning in the scrolling opening credits ;) Best regards, Hugo Harming upgraded@hotmail.com */ #include "mbed.h" #define LOW 0 #define HIGH 1 #define R_Debug1 0 #define R_Debug2 0 #define R_Debug3 0 #define R_Debug4 0 #define G_Debug1 0 #define G_Debug2 0 #define G_Debug3 0 #define G_Debug4 0 #define B_Debug1 0 #define B_Debug2 0 #define B_Debug3 0 #define B_Debug4 0 #define LED_Width 128 BusOut ABC(D8,D9,D10); // Row address.
