自行车LED点阵尾灯 3*max7219
本帖最后由 athlon789789 于 2013-4-16 11:57 编辑新手做的3个8*8点阵做的点阵尾灯带一点动画功能不过很麻烦要自己一帧一帧去做，有兴趣朋友可以自己试下。做这个东西最麻烦的部分是实现按钮的即时响应，因为动画免不了用到delay什么的。delay一出按钮什么的都完蛋了。代码比较暴力求高手指点优化一下，还有就是转向的时候可以响应按钮开关的，自己没有好办法了。max7219的库https://code.google.com/p/arudino-maxmatrix-library/downloads/list 我做了简单的修改可以实现测试功能和省电待机功能
#include <avr/pgmspace.h>
#include <MaxMatrix.h>//这个库我做了简单修改加入了关机功能测试功能
#include <Button.h>
#include "SimpleTimer.h"

无图无真相
有视频的哦 有意思有意思，有空也折騰一個{:soso_e144:} 参考 Arduino样例 Blink without Delay 那个警示灯超炫，有点像兰博的尾灯如果箭号没有尾巴就这的很像啦。。。 raphaelhhq 发表于 2013-4-16 20:39 static/image/common/back.gif
那个警示灯超炫，有点像兰博的尾灯如果箭号没有尾巴就这的很像啦。。。
直接可以修改，我怕别人看不清才加了尾巴 想要没有delay的话，建议显示部分单独写一个函数，再加一个cache作为图像显示缓存。通过定时中断的方式对显示的图像进行刷新，即可解决delay的问题。 这个想法确实不错,效果也挺玄的,只是在主循环中少用delay为妙,如果是顺序控制的程序,如有需要可以用delay,但是有即时的按钮需要按下就有反应,延时多了按钮反应就慢了.处理的办法是将Dalay"剔除"出主循环,再需要延迟的地方用中断或用计数器来判断,中断是时间到了再处理,时间不到继续循环,这样按键的反应会快许多.同理也可以用计数器来判断,这样效率也大大提高. 想问下如果两个8*8点阵max7219, 一个是比如’A‘字向走左和重复，另一个只是显示’B‘。有可能实现吗？一样信号咯。:) 你好我也想做一个这样的尾灯但是我是新手可否分享一下？ 看起来还不错。程序还可以再斟酌一下。
能共享一下库文件吗？ 顶一下:lol:lol:lol
