矩阵按键，数码管显示状态及选手，蜂鸣器提示音(Matrix keys, digital display status and player, buzzer prompt sound)

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

MSP430下CO2传感器MG811的驱动，附带电路图(The drive file of MG811 on the platform of msp430)

基于labview的gps定位，可以拿去用，都很完整(GPS positioning based on labview, can be used, are complete)

串口控制c源代码，自己看看，根据例程改的(Serial port control C source code)

SSD1306的OLED上显示字符、汉字、画点、画线、画圆的驱动函数，以及一个基于MSP430单片机的各个功能的测试文件。 整个文件采用模块化的划分方式，程序清晰容易阅读，适用于对OLED不熟悉的初学者直接移植使用，非常方便。(SSD1306 OLED display characters, Chinese characters, painting, line drawing, Circle Drive function, and one each function based on MSP430 single chip microcomputer test file. The entire file by dividing the modular, procedures clear and easy to read, suitable for beginners unfamiliar with OLED transplanted directly use, very convenient.)

HT1621是128点内存映象和多功能的LCD驱动器HT1621的软件配置特性使它适 用于多种LCD应用场合包括LCD模块和显示子系统用于连接主控制器和HT1621的管 脚只有4或5条HT1621还有一个节电命令用于降低系统功耗(HT1621 is 128 memory mapping and multi-function LCD drive HT1621 software configuration properties make it suitable Used for a variety of applications including LCD LCD module and display subsystem is used to connect the main controller and HT1621 tube Only 4 or 5 foot HT1621 there is a power saving command is used to reduce the power consumption of the system)

this is a program key test
