这个是I2C总线的程序，相信学过单片机的同学，应该都知道I2C总线，它是单片机中非常常见的一



个通信总线，且是非常重要的。很多的芯片都使用这种通信协议，比如DS1802温度传感器，DS1302



时钟芯片等都是使用这种通信协议的。所以，同于刚接触单片机的同学，一开始掌握这种通信协议



可能有点难度，所以，这个程序是比较通俗易懂，可以有效帮助您掌握I2C这个总线的控制。-This is the I2C bus procedures, I believe learned SCM students should know I2C bus, it is very common for a single-chip communication bus, and it is very important. Many are using this chip communication protocols, such as a temperature sensor DS1802, DS1302 clock chip, etc. are using this communication protocol. So, with the students in the fourth year of the microcontroller, beginning to master the communication protocol may be a bit difficult, so this procedure is relatively easy to understand, can effectively help you master the I2C control bus.
