Program for 5x7 COMMON CATHODE DOT MATRIX DISPLAY

进行速度的测量与监控，具有测速频率高，精度高，反馈效果好等优点(Speed measurement and monitoring has the advantages of high frequency, high accuracy and good feedback effect.)

说明：  簡單的串列埠自我測試持式 測試硬體電路是否正確(Chuanlibu simple self-test with tester hardware circuit is correct)

hadoop2.7.1最新源码,搭建方式及最新说明(hadoop2.7.1new srccode )

这是基于开发板LPC1114的源码程序，是用C语言编写，用于实现LED灯的点亮以及开关的控制，同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is based on the development board LPC1114 source code program, is written in C language, used to realize the lighting of LED lights and switch control, at the same time, it is also a complete template, you can add other programs on this basis for the development board learning, is a complete template, can be used directly.)

BEST BATTERY DESIGN WITH GRID.... PSCAD DESIGN....

C语言实现IEC104客户端，可以实现总召，遥信变位上送，YC上送。(The IEC104 client C language, you can achieve total Zhao, remote deformation on the YC sent.)

nrf51822 2.4g模块+uart+radio收发(nrf51822 2.4g+ uart+ radio transceiver module)

可以用指令控制选择信道，设置发射功率，发送数据包（长度可选），接收数据包（接收时延可设），CC2430复位,内部温度传感器读取，定时器时长控制。底层函数基本做好，如果要加入新功能，可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)
