用 MCS-51 单片机实现 I^2c 串行通讯规程

I 2c Serial Communication Regulation Realized by Using Single Chip 8031

分析了两线总线Ｉ２ｃ串行通讯规程及总线时序。阐述了如何利用ＭＣＳ－５１单片机的定时器中断，用纯软件的方法产生符合Ｉ２ｃ串行数据通讯规程的总线时序。

The bus regulation and time serise of I 2c serial communication are analyzed.It is explained that how to use single chip MCS 51 timer interrupt and software method, the time serise conforming with I 2c serial communication regulation is made.
