此文件为ipod程序，单片机用的是nec78f0547，用什么单片机我觉得无所为，这是我花了好长时间才弄完的，关键ipod协议太复杂了，贡献出来，希望对有需要的人一个帮助，一些命令我整理好了，在“ipod_procotol.txt”里面。-This file for ipod procedures, single-chip microcomputer is used nec78f0547, what I feel nothing for single-chip, which is I spent a good long time before the弄完key ipod agreement was too complicated, and contribute, in the hope that those who are in need of a help, I have collated a number of orders, and in

这是 freesscale smartDSP OS 测试 c 源的 evnet 队列。此演示创建三个任务，包括任务和事件队列 Initialization.The 的主要功能是系统功能测试的事件队列

适合于atmel 9200的uboot程序-suited to the atmel 9200 uboot procedures

课程作业写的代码，包含900多行用c语言写的51程序，其中包含LED显示模块、键盘模块、数字显示模块、蜂鸣器报警模块、步进电机控制模块、中断模块等等，是一个比较综合的程序

应用背景主要应用于51单片机的SD卡操作，完美适用于STC12c60s2单片机，现在的这方面的资源比较少，适用于51的更少，所以如果有需要这方面的资源，可以参考下，个人觉得很不错，已调通。关键技术51单片机的SD卡操作，完美适用于STC12c60s2单片机，函数有点大，住要是ZNFAT.C文件，里面是文件系统的主要函数，不过有些函数还未有待实验，SD.H文件的4个引脚可以根据自己的单片机自己定义，串口函数波特率为2400；

Presentation on Embedded C

The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated components, much in the same way as in other mature areas of engineering such as mechanical engineering and electronics. These guidelines have been used to develop Component-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic component types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.

1. 给主持人设置一个开关，用来控制系统的重启（编号显示数码管重置初始时间）和抢答器的倒计时开始。 2. 抢答器显示和倒计时的功能。抢答开始后，若有选手按动抢答器按钮，编号立即锁存，并在LED数码上显示选手的编号，同时扬声器给出音响提示。此外，要封锁输入电路，禁止其他选手抢答。 发挥部分： 1.
