利用单片机普通I/0口进行模拟IIC通信，从而实现24c02读写操作

DS18B20+LCD1602+AT24C02智能温度控制系统-DS18B20+ LCD1602+ AT24C02 intelligent temperature control system

在现代电子系统中，有为数众多的IC需要进行相互之间以及与外界的通信。为了提供硬件 的效率和简化电路的设计，PHILIPS开发了一种用于内部IC控制的简单的双向两线串行总线I2C-In modern electronic systems, there are a large number of IC need each other and communicate with the outside world. In order to provide the efficiency and simplify the hardware circuit design, PHILIPS developed an IC for internal control, a simple bi-directional two-wire serial bus I2C.

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.
