在pcDuino上搭载LoL Shield

[复制链接]
发表于 2013-12-20 10:14:05 | 显示全部楼层 |阅读模式
                                        LoL shield是一个可编程的14 x 9的LED矩阵,其上的每一个led都是单独可寻址的,所以你可以用它来显示任何一个14 x 9的网格。比如滚动文本,玩游戏,显示图像,或者其他任何你想做的事情。

               
       
实验元件:
                                                                                pcduino x 1
LoL shield x 1
               
       
                       
                                                                                pcduino上代码:
#include “core.h”
int blinkdelay = 75; //This basically controls brightness. Lower is dimmer
int runspeed = 20; //smaller = faster
int pin13 =13;

int pin09 =9;

实验效果:
led从左上角开始沿着斜对角一行一行地被点亮。然后所有的led亮了之后再从左上角开始一行一行地熄灭。
