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）
