LEDtest

编写程序，通过8255 单元控制点阵的扫描显示，使8×8LED 点阵到小循环显示号 “□”(Programming, through the 8255 unit control the scanning dot matrix display, the 8 × 8LED dot matrix display number to small cycles " □" )

51单片机控制12864液晶，适合初学者入门使用，简单方面，易于移植(51 12864 LCD, suitable for beginners to use, simple terms, easy to transplant)

基于MSP430G2553的频率计数计的程序编写，已经过测试，程序无误可以完整运行。(Based on the frequency count MSP430G2553 meter programming, has been tested, the program can complete run correctly.)

DHT11的C51驱动程序，4位数码管可以显示温度和湿度，带一触发按键(DHT11 C51 driver, four digital tube can display temperature and humidity, with a trigger button)

IRMCK171的FOC控制无刷电机控制原理图 IR内部资料啊(Control of IRMCK171 FOC brushless motor control schematic IR internal data)

AVR单片机应用系统开发典型实例 包含电路图，C语言源码及 ICCAVR的软硬仿文件(AVR single-chip applications include the development of a typical circuit example, C language source code and documentation ICCAVR like the soft and hard)

使用MSP430F5438单片机和HC-SR04超声波模块实现测距的源码。( Using the MSP430F5438 microcontroller and HC-SR04 ultrasonic ranging module source.)

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. )

本文介绍一种利用单片机本身所提供的串行通讯口，采用自定义串行通信协议，加上总线驱动器如MAX481、MAX483、MAX485、MAX487等组合成简单的RS－485通讯网络，完成单片机间的多机通讯。(This article describes a serial communication port provided by the microcontroller itself, the custom serial communication protocols, coupled with the bus driver, such as the MAX481, MAX483, MAX485, MAX487, combined into a simple RS-485 communication network, complete single-chip between themulti-machine communication. )
