标题: IIC初学所写的一些程序
溜达一圈，刚回来，昨晚弄IIC，搞得晚上都没睡好觉，难得昨天天气很好，室温20度，穿一件内衣都可以了；
IIC 协议用郭天祥书本上现成的，记得以前帮MM搞毕业设计时LCD上的串行协议也是用他的；
反正，这个协议完全应该可以当成标准品来用了，感觉一段时间没玩代码，又似乎回到了起点；
单字节读写没有问题；今天准备把多字节给

弄上去（书上没有），写着写着，发现有点麻烦，哎，先上单字节的程序了；

昨天，晚上也难眠；
上午起得比较晚，坐在床上弹了一个上午的吉他，只是自已从来没有认真练过弹与唱，有点感觉了的时候就投入了；
今天，终于调通了IIC—AT24C04，写了一个时钟程序，每隔一秒钟把时分秒往AT24C04里写一次；
这样上电后就记录了断电时的数据；
下午，一个员工一边玩我的电脑，和我扯谈了一个下午，扯得我嗓子都痛了；
呵呵，我真不知我这么菜的，还能不能接上外单业务，这个我还真没把握，没想过要赚得多少钱；
只是想玩玩，可是发现如果没投入进去，又老是觉得不过隐；
好了，到这基本可以上路了，天马行空，自由发挥啊！
上程序了：且看，往IIC里面写数据，要延时啊，不然数据老是不对；1T的芯片啊！
