This is LM3S9B92 Sample Code data

基于VC++的，以操作文件的方式（CreateFile,WirteFile,ReadFile）来操作串口实现的射频卡门禁系统，实现了包括读卡写卡，寻卡防冲突等功能。(Based VC++ in order to manipulate papers (CreateFile, WirteFile, ReadFile) to operate the serial interface of the RF card access control systems, including the realization of the card reader to write, look for cards anti-collision function.)

使用方法： 程序设置了ENC28J60的IP为192.168.0.15，模块通电后与电脑的网口用网线连接起来， 设置电脑的本地IP为192.168.0.**（**自定），网关为192.168.0.15,其他默认，配置 成功后便可以arp或ping模块。 打开浏览器，在地址里输入http://192.168.0.15/123456可打开开发板简单网页，页 面上通过按键来控制开发板LED的亮灭。(Use: setup the ENC28J60 of IP to 192.168.0.15, the module is powered on the computer' s Ethernet port using a cable connection up to set the computer' s local IP 192.168.0.** (** Custom), the gateway 192.168.0.15, default configuration is successful, it will make arp or ping module. Open the browser, enter the address http://192.168.0.15/123456 to open the development board simple web pages, and page keys to control the development board LED light off.)

STM32F405 CAN程序，亲测可用(forSTM32F405 project itis OK)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
