用C实现广告灯箱自动装置1、直流电机控制系统，控制广告牌的升降。 2、定时翻转广告，可由按键设定时长。 3、时间设置，5：00-22：00正常工作，其余时间不工作，时间可以调整。 4、到达广告的边缘部分广告停止翻转。 5、广告可以由按键设置升/降。 6、白天时间广告灯不亮，光线较暗时广告灯才亮，测试灯的好坏时可以手动控制灯光。 7、断电时保存时间及按键的设置，使广告牌到达边缘部分。 -C implementation using automatic device 1 advertisement light box, DC motor control system, control the rise and fall of advertising. 2, ads from time to time reversal, length of time set by the keys. 3, time set ,5:00-22: 00 normal job, the rest of the time does not work, time to adjust. 4, Get ads ads stop some of the edge flip. 5, ads can be set up by the button/drop. 6, ads during the day time lights are not bright, low light only bright lights when the ads to test the quality of light can control the lights manually. 7, when power-off time and save the settings button so that the edge part of advertising arrival.

kfs嵌入式文件系统1.0.1release版 作者：Eagle 来源：http://www.embseek.com 由embseek开发，专门针对小容量的EEPROM和FLASH等存储器，应用于无操作系统的嵌入式系统中。实现了类似于标准文件操作的接口。压缩包内有在pc下使用ram调试的示例代码。 1.0.1release版本更新内容 修改文件系统初始化api，使用开始地址和结束地址作为参数 修正了文件创建api，添加文件打开模式开关 修正文件碎片管理功能，现在已经不会出现文件碎片啦！ 修正了文件系统当前首地址存放方式.-kfs 1.0.1release Embedded File System Version Author : Eagle Source : http://www.embseek.com by embseek development, specifically aimed at small capacity, such as EEPROM and FLASH memory, No operating system for embedded systems. Achieve similar to the standard file manipulation interface. Compressed within the pc use of the ram debugging code examples. 1.0.1release updated version to modify the file system initialization api. use starting address and ending address as a parameter that the file creation api. Add open mode switch that debris document management functions, it is now no document debris! That the first file system addresses the current storage methods.

应用背景本源码例子是基于交换的VLAN配置的，基本的VLAN配置里面都有，这是配置底层的，不是用命令配置的。关键技术对于刚进入嵌入式学习的朋友很有帮助，都是交换机的配置

我自己写的一个非常简单的ARM的流水灯实验，希望对刚开始ARM的同学有帮助-I wrote it myself a very simple experiment ARM-water light and hope are just starting out help students ARM

matlab的应用，关于线性回归的。 值得参考。-matlab applications, on the linear regression. Worth considering.
