说明：  答题器源码，用51单片机控制的。具体内容自己下载看吧(Answer source browser, with 51 single-chip control. Download and see the specific content of their own)

网络控制单片机proteus仿真 利用网络控制单片机的LED、LCD，我只是整理了一下，方便大家学习，版权归原作者，网页也麻烦站长做好了，有一个上位机，点击自动运行一段程序和打开www.mcufz.com/tcp.htm，之后会自动关闭，有的杀毒软件会报是病毒，放心使用。 开始要安装一个WinPcap软件，不安装它不能仿真，然后运行仿真文件，过一会可以看到LCD显示出了IP地址50。1。1。1 (Proteus simulation network control the use of single-chip microcontroller network control LED, LCD, I am just finishing a bit, to facilitate learning, belongs to original author, the website also do a good job of head trouble, there is a host computer, click Automatic operation for some procedures and open www.mcufz.com/tcp.htm, will automatically shut down after some anti-virus software will be reported to viruses, ease of use. WinPcap started to install a software, do not install it can not simulation, and then run the simulation documents LCD moment we can see the IP addresses shows that 50. 1. 1.1)

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)

电子科大单片机综合实验，功能包括 温度检测 转速测速 温度设定 温差驱动电机速度 按键使用 I2C通信 ，数码管显示 速度 设定温度 实际温度。是个综合学习51单片机的好例子。 (UESTC integrated single-chip experiments, including temperature detection speed tachometer temperature settings temperature difference driving the motor speed keys using I2C communication, digital display speed set temperature actual temperature. Is a good example of a comprehensive study of 51 single-chip.)

iOS 网络状态监测。网络实时检测，用到Reachability（自行下载）,需加框架:SystemConfiguration.framework ios程序需要用到网络检测，有些程序是刚启动时检测一次，而有些则从头到尾检测网络状态。(IOS network status monitoring.Real-time detection and Reachability (download), frame: SystemConfiguration.framework IOS programs need to use network detection, some detection once when the program is launched, while others detect the network status start to finish.)

51单片机入门学习资料，适合初学者下载。(Getting Started 51 MCU learning materials, suitable for beginners to download.)

Code written in MPLAB for I2C with PIC18f45k80

bms 管理软件，c语言编写，基于单片机编写(bms management software, c language,)

包含位置式PID算法、积分分离式PID，包括广义互相关函数GCC时延估计，真的是一个好程序。( It contains positional PID algorithm, integral separate PID, Including the generalized cross-correlation function GCC time delay estimation, Really is a good program.)
