嵌入式跑马灯实验报告总结(嵌入式跑马灯实验报告总结)

LED跑马灯程序

很简单，你把数字 3 转换成 32位的 二进制表示方式：

3 = 0000 0000 0000 0000 0000 0000 0000 0011

二进制，通常我们这么称呼，最右边的位是最低位，称为bit0，即第0位，对于32位，最左边的是最高位，我们称为bit31，即第31位。

通过上面的转换，想必你看清楚了，3的第1位和第0位为11，那么，向左移了10次后，那两个 1 被移动到了第11位和第10位上，所以就是你看到的结果了。

为了探索商用LED跑马灯的利用价值，真正实现其开发便捷，使用方便，价格低廉的特点，特设计基于嵌入式Linux系统的跑马灯。随着信息时代的走进，嵌入式Linux系统逐渐被人们看好及广泛应用于商用领域，我们通过探索实验得出，做LED跑马灯基于嵌入式Linux系统是便捷、快速、成本小、开发周期短的一个最好办法。本文主要介绍了嵌入式的概况及应用领域，嵌入式Linux系统的概况及发展趋势，还简单的介绍了我们试验中要用到得ARM9实验板的概况，总之在本文中既有嵌入式的软件又有嵌入式硬件方面的内容，都很详细。通过大量前期资料的整理，我们在Linux环境中编译出了LED跑马灯的驱动程序和应用程序，通过交叉编译在ARM9实验板上运行并最终实验测试结果正常，达到我们要实验的目的。结果表明，基于嵌入式Linux系统LED跑马灯的设计与实现，是最便捷，简单，开发周期短的方式。在开发结果我们也看出LED跑马灯用嵌入式Linux系统编译，在Linux系统的开发环境下运行良好，如我们大家所期待达到我们所要求的实验目的，并从中表现出极好的运行性能和安全性能。

Make use of value for probing commercial LED horse race light's , truly put into effect whose exploitation is convenient and rapid , usage goes to the lavatory , the cheap characteristic of price , the secret agent design that owing to implanting dyadic systematic Linux horse race light. With the fact that the information ear walking moves forward, dyadic implantation Linux system is found the commercial field satisfactory and applied to broadly gradually by people, that we reach , make LED horse race light by probing an experiment is convenient and rapid owing to implanting dyadic Linux system , the fleetness , cost develop a short best way of period for a short time. Implant the dyadic general situation and application field that the main body of a book has been introduced mainly , implant the dyadic systematic general situation of Linux and developing trend, unnatural general situation having introduced that we need to use to getting the ARM9 experiment in the experiment fairly simplely, the content both have aspect to implant the dyadic software and have to implant the dyadic hardware in the main body of a book, is in short , all very detailed. Arranging by large amount of the earlier stage data , our driver and application having compiled and translated out LED horse race light in the environment in Linux, that the work and ultimate experiment tests result by intersection compile and translate on ARM9 experiment board is regular , achieve our essential points experiment's purpose.Result is indicated, owing to the design implanting dyadic Linux system LED horse race light and the way coming true , being convenient and rapid , simple , developing a period shortly. We also perceive LED horse race light in the result developing using dyadic implantation Linux system to compile and translate , operation is fine under systematic Linux exploitation environment, if what all of us expects to achieve what our demands experiment purpose, and is extremely good out of runs the function and the safe function.

本文在介绍嵌入式Linux系统的基础上，研究在LED跑马灯方面的应用，引用嵌入式Linux系统跑马灯设计训练过程及测试结果，最后通过交叉编译，实现了基于嵌入式Linux系统的跑马灯设计能够取得比较好的效果。

The systematic basis is listed in the main body of a book in Linux introducing implantation style , is study the application in the field of LED horse race light, the horse race light quoting dyadic implantation Linux system horse race light designing the system training process and testing result , the at last having come true by intersection compile and translate, owing to implanting dyadic Linux designs that being able to get comparatively good effect.

这样就可以了。希望能帮到你。

嵌入式开发跑马灯实验，为什么这个代码不能点亮？其他都没错，就这里错了，看视频上的都可以

建议你尝试把odr配置管脚高低的方式换成PBOUT(5)和PEOUT(5)的方式。

跑马灯实验如何改变灯移动的频率

1、首先打开跑马灯实验。

2、其次在程序中修改speed的数值。

3、最后即可改变灯移动的频率。

keil5跑马灯的实验效果是啥

延时实现LED流水灯效果。端口的八个灯作跑马灯。在本实验中，作为输出口，接8只发光二极管，编写程序，使发光二极管循环点亮。达到延时实现LED流水灯效果。

跑马灯的原理

跑马灯实际上运作的方式说穿了很简单,程式先定义一段要展示的原始字串.然后从原始字串中抽取一小段的文字显示出来.每次取这一小段的文字时.都比上次所取时位置稍候.因此造成了卷动的效果.
