单片机与温度传感器的应用，很多错的。请大家踊跃下载啊。-SCM and temperature sensor applications, a lot of wrong. Please download ah enthusiastically.

利用51单片机控制DS18B20温度传感器采集温度，并利用无线传输模块PTR6000将温度值进行传送，很实用的程序，绝对原创和好使！-SCM control DS18B20 using 51 temperature sensors collect temperature, and using wireless transmission module PTR6000 to send the temperature value is very useful procedure, the absolute original and so!

利用ps2键盘向单片机输入数据，这样做不仅可以减少输入输出口，而且程序代码短小精悍，可以极大的提高单片机的执行效率．-Ps2 keyboard to use single-chip input data, to do so not only can reduce the input and output port, and program code dapper, you can greatly improve efficiency in the implementation of SCM.

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current state of light

电机调速是单片机或DSP硬件平台结合电机运行机制设计相应算法，并以软件实现-Motor speed is a microcontroller or DSP hardware platforms, operating mechanism with electrical design corresponding algorithms, and to software implementation

Modbus是modicom公司提出得一种数据传送方式, 也是现在用的较多的现场总线之一,之所以它这么成功得被应用, 主要原因是因为Modbus协议的简单,和开放性较好-Modbus is modicom companies have a data transmission method is now used more fieldbus one reason why it was such a successful application, the main reason is because the Modbus protocol is simple, and openness better
