第二次作业：http://forum.eepw.com.cn/thread/277609/1#3（流水灯）
第三次作业：http://forum.eepw.com.cn/thread/277609/1#4（数码管显示0-99）
第四次作业：http://forum.eepw.com.cn/thread/277609/1#6（单号：串口控制led）
第五次作业：http://forum.eepw.com.cn/thread/277609/1#7（用一个定时器制作跑马灯）
第六次作业：http://forum.eepw.com.cn/thread/277609/1#8（ADC改变灯的颜色）
二选一题目：http://forum.eepw.com.cn/thread/277609/1#9（触摸DS18B02改变灯的颜色）
MDK的安装
首先，先找到安装包的文件夹，双击红色圈里的mdk472_a.exe，开始安装
打开mdk472_a.exe，就出现下面的界面，点击next
勾上I agree to all the terms of the ……，然后再点击next
选择安装目录，把它放到E盘MDK文件夹下，再点击next
把First Name和E-mail填上
接下来就是等待安装了，装好后会跳出一个界面，点击next
框框里有两个勾不用选，点击finsh
装好后点击桌面的快捷方式打开软件，点击File/License Management就出现下面这个界面
接下来需要打开和谐文件和谐一下，然后把License Management界面右边的CID复制到和谐文件的CID里，然后Target选择的是ARM，Generate多点击几次，把里面的内容复制到License Management里New License ID Code(LIC)里，点击Add
最后就关闭这个软件再重新打开就可以用了
