i2c程序，可以直接调用，用51单片机开发。-i2c procedures can be called directly, with 51 MCU Development.

功能：实现对DS18B20的读取 原理：单总线协议 注意：单总线协议对延时要求比较严格，此程序中采用的是11.0592M的晶振，如果使用其他的晶振请跟据DS18B20的资料修改延时参数-functions : to achieve DS18B20 read Principle : single-bus protocol attention : single-bus protocol to delay requirements more stringent, this procedure is used in the crystal 11.0592M if the use of other crystal please According to the information DS18B20 delay parameter changes

用ATmega8单片机产生占空比可变PWM方波-ATmega8 generated by single-chip PWM variable duty cycle square wave

状态1：正常时，8个LED发光二极管（彩灯）循环点亮。 • 状态2：有报警时，蜂鸣器发出报警声（用P3.3接一个按键，模拟产生报警信号。当开关合上，发生报警；当开关断开，报警停止。用P3.7输出音频信号驱动扬声器，作为报警信号），同时8个LED发光二极管（彩灯）闪烁。 P3.2接一个按键，用于消除报警-Status 1: normal, eight LED light-emitting diodes (lantern) light cycle.
