用并口通信时,只需发送仿真软件的十六进制显示窗口的第四个字节后的所有数据。 如:清全屏的十六进制显示窗口是55AA0001434C42,采用并口通信时只需发送434C42-with Parallel Communications, only this simulation software hexadecimal display window of words, after the data. Such as : a full-hexadecimal 55AA0001434C42 show window is used and only parallel communication sent 434C42

温度传感器DS18B20测温+显示+键盘，里面包括KEIL文件和PROTEUS仿真文件-Temperature sensor DS18B20 temperature+ Display+ Keyboard, which includes documents and PROTEUS simulation KEIL document

这是温度传感器PT100的使用心得，希望对大家有所用。-PT100 temperature sensor which is the use of experience, I hope with all of you.

keilc51中stc芯片补丁，用于stc系列芯片的开发-STC chip in keilc51 patch for the development of STC series chip

这是一个关于数码管移动的程序，非常好用，适合于初学者-This is a movement on the digital control program, very easy to use, suitable for beginners

PWM波程序 可以用来控制电机调速，程序比较简单，这里只用了一个定时器就实现了。因为51单片机没有PWM波的寄存器，所以要自己用软件控制。-PWM waves program can be used to control motor speed, procedure is simple, here only a timer is realized. Because no PWM waves 51-series microcomputer to yourself, so with registers control software.

80c51与ISD4003应用程序，功能挺好的，我希望大家喜欢吧-80C51 with ISD4003 applications, features very good, and I hope everyone likes it
