说明：  proteus仿真实例：IIC-24C04和数码管显示。学习单片机时使用proteus进行仿真是再好不过了。这里以数码管为媒介，介绍IIC的一般方法，对于刚学IIC而言是比较合适的，因为我自己学习时也是从这些比较简单但是格式较规范的实例学起的。
(proteus simulation: IIC-24C04 and digital display. Learning to use proteus simulation SCM is better. Here the medium of digital control to introduce the general method of IIC, the IIC just in terms of learning is more appropriate, because when I learn also from these simple examples, but the format than the standard school starting.)
