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.)

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.)

基于ARM9的星际漫游机器人，能够自主循迹，碰到障碍物后会自动返回(ARM9-based the interstellar roaming robots, autonomous tracking, automatically returns after tripping over obstacles)

这个是我自己编写的，小车程序，通过H桥控制电机运转，实现小车的行走功能，已经激光判断，循迹，判别路口转弯(This is what I have written, car program, controlled by H-bridge motor running, walking function to achieve the car has a laser judgment, tracking, discrimination intersection turn)
