动态口令认证，skey协议，实现身份鉴别过程。(Dynamic password authentication, skey protocol, identity authentication process.)

P89LPC924_program已介绍如何应用其各种基本功能(P89LPC924_program)

μC/GUI 是一种用于嵌入式应用的图形支持软件。它被设计用于为任何使用一个图形LCD 的应用提供一个有效的不依赖于处理器和LCD 控制器的图形用户接口。它能工作于单任务或 多任务的系统环境下。μC/GUI 适用于使用任何LCD 控制和CPU 的任何尺寸的物理和虚拟显示。 它的设计是模块化的，由在不同的模块中的不同的层组成。一个层，称作LCD 驱动程序，包 含了对LCD 的全部访问。μC/GUI 适用于所有的CPU，因为它100 由的ANSI 的C 语言编写的。(μC/GUI is a graphical support software for embedded applications. It is designed to provide an effective does not rely on a graphical user interface of the processor and an LCD controller of any use of the application of a graphic LCD. The system can work on a single task or multiple tasks environment. μC/GUI for any LCD controller and CPU of any size physical and virtual display. Its design is modular, composed of different layers in different modules. A layer, called the LCD driver, including full access to the LCD. μC/GUI applies to all of the CPU, because it is 100 written in ANSI C language.)

MSP430实现的多级菜单功能，采用OLED实现，占用Ram量较少(MSP430 realize multi-level menu functions, the use of OLED achieved occupancy of less Ram)

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.)

步进电机驱动，四相五线步进电机控制的测试程序，C51编写，读者可稍加修给即可应用(Stepper motor driver)

说明：  基于avr单片机的对sd卡（MMC）驱动程序(Avr microcontroller based on the sd card (MMC) Driver)

气源环境监控系统设计与实现Air Supply Design and implementation of environmental monitoring system(Air Supply Design and implementation of environmental monitoring system)

串口中断例子，可以解决接受数据不显示第一个字符的问题(Serial interrupt example, can solve the problem of receiving data does not display the first character)

本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)
