  一段时间没有更新博客了,最近忙着给别人做项目呢,说来还有点不好意思,我所说的项目是给大四的毕业生做毕业设计,但我相信这是第一步,以后我也可以进行工业项目的研发的。

      昨天成功交了一个活儿,拿到了700块钱,真心心情不错。今天是五一劳动节,室友们都出去玩儿了,其实我也挺想出去逛逛的,不是为了玩,是为了见见世面,可是我现在的情况真的不适合,也没有钱,这几天我把节奏放慢了一点,看看电影,听听歌,写写博客,好好睡个觉,也挺好。每次写博客之前我总是唠叨一下自己,是一种倾诉吧,也是一种自我鼓励,,,

     不想写什么原理之类的了,太大陆货儿了,只是把原理图,和程序传上来,让如果想做类似东西的朋友们参考一下吧。

       要求(老板要求实现的功能):

有3个控制按键:K1,模式选择键;   K2,增速键;K3,减速键。
    增速与减速模式,各要有至少3种,(包括原档位,共4种档位)即:按一下K2,速度增加,再按下K2,增速继续增加,再按下K2,增速继续增加;按一下K3,速度减少,再按下K3,速度继续减少,再按下K3,速度继续减少。

    各种模式要类似广告流水灯,是从8*8点阵左→右移动,速度是指左→右的移动速度。
    8种模式的内容要不相同。
      如:
                   模式一  实现正向流动显示 eec fly;
          模式二:实现反向流动显示 eec fly;
          模式三:数字顺序显示 1 2 3 4 5;
          模式四:字母顺序显示,A  B  C  D  E;
          模式五:花样灯1;(图形1)
          模式六:花样灯2,(图形2)
