connection的两种连通域方法，上传上去大家应该能看懂的，我从基础学的是能够看得懂，不懂得翻下书(The connection of the two methods of connected domain, uploaded you should be able to understand, I the foundation to learn is to be able to read, not understand through books)

说明：  TM4C123GH6PM ADC采样，uart输出成功实例(Successful example of tm4c123gh6pm ADC sampling and UART output)

说明：  无刷电机驱动器源代码。基于无传感器方案的无刷电机启动器。核心是换向角度检测：即电机反电势波形数据处理，经过衰减滤波，取出过零相位。应为低速反电势波形dB过小，波形扰动太大，本程序还不能稳定处理10Hz以下的换向计算。(Brushless motor driver source code. Program based on the sensorless brushless motor starter. Is the core to the point of view for detection: the motor back-EMF waveform data processing, through the attenuation filter, remove the zero-crossing phase. For low-speed back-EMF waveform dB is too small, waveform disturbance too, this procedure can not be stabilized to 10Hz for the following calculation.)

说明：  大家共享，需要的话自己下 仅供参考，正确与否，认真审查(Share, if necessary, under their own for reference purposes only, correct or not, a careful review of)

利用opencv进行电脑摄像头检测，可以实时检测到人脸，进行目标跟踪，代码可以下下来看看用用，有需要的可以试一试哦。

基于GDAL读取shp线文件，基于Fwtools工具实现，

程序是一个可执行文件，程序是把flash编译成的可执行文件转换成swf类型．(Program is an executable file, the program is to compile the executable file flash convert swf type.)

简单的四则运算程序，用c语言编写， 在程序中最多只能有3个数字与3个运算符号的运算。 程序包括主函数main. 与 计算函数cal(); 需要比较运算优先级。程序一览如下所示。 #include main()         {           int i, j = 4;        

1.数据时随机产生的（产生1000个随机数），进行排序2.每一次数据排序之后，都可以看到排序的移动，交换次数以及排序的时间。 (1. After randomly generated data (generated 1000 random numbers), every sort 2. Sort the data, you can see the sort of move, switching times and sort of time.)

配电网零序电流故障定位方法在PSCAD中的模型搭建，可以调整故障类型和短路电阻等进行故障模拟(The fault location method of zero sequence current in distribution network is built in PSCAD, which can adjust the fault type and short circuit resistance. )
