嵌入式linux驱动要学哪些

代表你的基础已经很好了,嵌入式学习相关的基础知识主要是这些: 一是程序设计的基础,例如:基本的编程语言基础,至少对数据类型、程序的结构及流程控制等最基本的内容要相当清楚,所以建议恶补一下C语言,推荐谭浩强的C语言程序设计,好好看一下,呵呵!另外有不少同学都问到数据结构的基础,我一直认为数据结构和算法的学习是帮助形成程序设计逻辑思维的很好训练方式,对于程序员的长期专业素养的提高一定有好处,所以建议即使已经在嵌入式行业中工作之后也应该多补充一些相关的知识。许多在学校没有学过数据结构的同学往往认为这部分非常枯燥、难学。而实际上如果你能明白研究计算机存储和数据组织方式的意义,就一定能够充分体会到数据结构的价值和魅力。一旦兴趣有了,一切就会迎刃而解,呵呵! 二是操作系统工作原理,这部分往往是非计算机专业的同学在学校时没有接触过的。而由于嵌入式软件设计相关的多任务环境、模块间的同步与通信协同、驱动设计等往往都需要有对操作系统工作机制的了解和掌握作为基础,因此建议没有系统学习过的同学,找一本相关的操作系统工作原理书籍认真看一下(不用特厚、特专业、特内核的,先以普及知识为主,呵呵!)。 三是基本的硬件基础,由于嵌入式Linux开发往往是ARMLinux路线,所以为了能够在后续学习过程中很好地掌握主流嵌入式微处理器的结构与原理(例如:ARM9),就需要对硬件工作原理有初步的了解和掌握,建议看一下诸如计算机组成原理、体系结构等相关的专业书籍。 要深入学习你可以尝试以下路线: (1) C语言是所有编程语言中的强者,单片机、DSP、类似ARM的种种芯片的编程都可以用C语言搞定),因此必须非常熟练的掌握。 推荐书籍:《The C Programming Language》 这本经典的教材是老外写的,也有中译版本。 (2) 操作系统原理,是必需的,如果你是计算机专业毕业那也就无所谓了,如果是非计算机专业的就必须找一本比较浅显的计算机原理书籍看一看,把啥叫“进程”“线程”“系统调度”等等基本问题搞清楚。 (3)Linux操作系统就是用C语言编写的,所以你也应该先学习下Linux方面的编程,只有你会应用了,才能近一步去了解其内核的精髓。 推荐书籍:《UNIX环境高级编程》(第2版) (4) 了解ARM的架构,原理,以及其汇编指令,我们在嵌入式开发中,一般很少去写汇编,但是最起码的要求是能够看懂arm汇编。 (5) 系统移植的时候,就需要你从最下层的bootloader开始,然后内核移植,文件系统移植等。而移植这部分对硬件的依赖是非常大的,其配置步骤也相对复杂,也没有太多详细资料。 (6) 驱动开发 linux驱动程序设计既是个极富有挑战性的领域,又是一个博大精深的内容。 linux驱动程序设计本质是属于linux内核编程范畴的,因而是对linux内核和内核编程是有要求的。在学习前你要想了解linux内核的组成,因为每一部分要详细研究的话足够可以扩展成一本厚书。 以上只不过是大概的框架,在实际的开发中还会涉及很多东西,比如:交叉编译、makefile、shell脚本等等,所以说学习嵌入式的周期较长,门槛较高,自学的话更是需要较强的学习能力和专业功底。只要能坚持下来一定会取得成功! 华清远见的嵌入式专业教材比较专业,也很出名,高校图书馆以及外面书店都有卖,你可以去网上搜一下,买本看看,华清远见的网站和技术论坛上面也有很多嵌入式学习资料和视频可以下载,而且更新的速度也很快,LZ没事可以去转转,相信对你会有帮助! 另外,虚机团上产品团购,超级便宜

嵌入式Linux驱动程序开发学习路线

嵌入式Linux驱动程序开发学习路线

关于这个方向,我认为大概分3个阶段: 1、嵌入式linux上层应用,包括QT的GUI开发 2、嵌入式linux系统开发 3、嵌入式linux驱动开发 嵌入式目前主要面向的几个操作系统是,LINUX,WINCE、VxWorks等等 Linux是开源免费的,而且其源代码是开放的,更加适合我们学习嵌入式。 所以你可以尝试以下路线: (1)C语言是所有编程语言中的强者,单片机、DSP、类似ARM的种种芯片的编程都可以用C语言搞定),因此必须非常熟练的掌握。 推荐书籍:《TheCProgrammingLanguage》这本经典的教材是老外写的,也有中译版本。 (2)操作系统原理,是必需的,如果你是计算机专业毕业那也就无所谓了,如果是非计算机专业的就必须找一本比较浅显的计算机原理书籍看一看,把啥叫“进程”“线程”“系统调度”等等基本问题搞清楚。 (3)Linux操作系统就是用C语言编写的,所以你也应该先学习下Linux方面的编程,只有你会应用了,才能近一步去了解其内核的精髓。 推荐书籍:《UNIX环境高级编程》(第2版) (4)了解ARM的架构,原理,以及其汇编指令,我们在嵌入式开发中,一般很少去写汇编,但是最起码的要求是能够看懂arm汇编。 (5)系统移植的时候,就需要你从最下层的bootloader开始,然后内核移植,文件系统移植等。而移植这部分对硬件的依赖是非常大的,其配置步骤也相对复杂,也没有太多详细资料。 (6)驱动开发 linux驱动程序设计既是个极富有挑战性的领域,又是一个博大精深的内容。 linux驱动程序设计本质是属于linux内核编程范畴的,因而是对linux内核和内核编程是有要求的。在学习前你要想了解linux内核的组成,因为每一部分要详细研究的话足够可以扩展成一本厚书。 以上只不过是大概的框架,在实际的开发中还会涉及很多东西,比如:交叉编译、makefile、shell脚本等等,所以说学习嵌入式的周期较长,门槛较高,自学的话更是需要较强的学习能力和专业功底。只要能坚持下来一定会取得成功! 嵌入式非常难,看书的话比较晦涩难懂,不容易入门,我个人比较偏向于看视频教程,因为有老师带着比较容易入门。给看看一篇文章是关于一位专科生怎么自学嵌入式的。 做个自我介绍,我07年考上一所很烂专科民办的学校,学的是生物专业,具体的学校名称我就不说出来献丑了。09年我就辍学了,我在那样的学校,一年学费要1万多,但是根本没有人学习,我实在看不到希望,我就退学了。 退学后我也迷茫,大专都没有毕业,我真的不知道我能干什么,我在纠结着我能做什么。所以辍学后我一段时间,我想去找工作,因为我比较沉默寡言,不是很会说话,我不适合去应聘做业务。我想应聘做技术的,可是处处碰壁。 一次偶然的机会,我才听到嵌入式这个行业。那天我去新华书店,在计算机分类那边想找本书学习。后来有个女孩子走过来,问我是不是读计算机的,有没有兴趣学习嵌入式,然后给我介绍了一下嵌入式现在的火热情况,告诉我学嵌入式多么的有前景,给我了一份传单,嵌入式培训的广告。听了她的介绍,我心里痒痒的,确实我很想去学会一门自己的技术,靠自己的双手吃饭。 回家后,我就上网查了下嵌入式,确实是当今比较热门的行业,也是比较好找工作的,工资也是相对比较高。我就下决心想学嵌入式了。于是我去找嵌入式培训的相关信息,说真的,我也很迷茫,我不知道培训是否真的能像他们宣传的那样好,所以我就想了解一段时间再做打算。 后来,我在百度知道看到一篇让我很鼓舞的文章,是一个嵌入式高手介绍没有基础的朋友怎么自学入门学嵌入式,文章写的很好,包含了如何学习,该怎么学习。他提到一个方法就是看视频,因为看书实在太枯燥和费解的,很多我们也看不懂。这点我真的很认同,我自己看书往往看不了几页。 我在想,为什么别人都能自学成才,我也可以的!我要相信自己,所以我就想自学,如果实在学不会我再去培训。 主意一定,我就去搜索嵌入式的视频,虽然零星找到一些嵌入式的视频,但是都不系统,我是想找一个能够告诉我该怎么学的视频,一套从入门到精通的视频,一个比较完整的资料,最好能有老师教,不懂可以请教的。 后来我又找到一份很好的视频,是在IT学习联盟网站推出的一份视频《零基础嵌入式就业班》(喜欢《零基础嵌入式就业班》的可以复制sina.lt/qKh粘贴浏览器按回车键即打开)。里面的教程还不错,很完整,可以让我从基础的开始学起。视频比较便宜。 下面介绍下我的学习流程,希望对和我一样完全没有基础的朋友有所帮助。 收到他们寄过来的光盘后,我就开始学习了,由于我没有什么基础,我就从最简单的C语言视频教程学起,话说简单,其实我还是很多不懂的,我只好请教他们,他们还是很热心的,都帮我解决了。C语言我差不多学了一个礼拜,接下来我就学了linux的基本命令,我在他们提供linux虚拟机上都有做练习,敲linux的基本命令,写简单的C语言代码,差不多也就三个礼拜。我每天都在不停的写一些简单的代码,这样一月后我基本掌握了C和linux的基本操作。 接下来我就去学习了人家的视频的培训教程,是整套的,和去参加培训没有多大的区别,这一看就是两个月,学习了ARM的基本原理,学习嵌入式系统的概念,也掌握了嵌入式的环境的一些搭建,对linux也有更深层次的理解了,明白了嵌入式应用到底是怎么做的,但是驱动我只是有一点点的了解,这个相对难一点,我想以后再慢慢啃。 这两个月,除了吃饭睡觉,我几乎都在学习。因为我知道几乎没有基础,比别人差劲,我只能坚持努力着,我不能放弃,我必要要靠自己来养活自己,必须学好这门技术,然后我就把不懂的问题总结记下来,这样慢慢积累了一段时间,我发现自己真的有点入门了。 最后的一个月,我就去看关于实践部分的内容,了解嵌入式项目具体的开发流程,需要什么样的知识,我就开始准备这方面的知识,也就是学习这方面的视频,同时他们建议我去找了找一些嵌入式面试的题目,为自己以后找工作做准备。我就到网上找了很多嵌入式的题目,把他们理解的记下来,这样差不多准备了20天左右 我觉得自己差不多入门了,会做一些简单的东西了。我就想去找工作看看,于是我就到51job疯狂的投简历,因为我学历的问题,专科没有毕业,说真的,大公司没有人会要我,所以我投的都是民营的小公司,我希望自己的努力有所回报。没有想过几天过后,就有面试了,但是第一次面试我失败了,虽然我自认为笔试很好,因为我之前做了准备,但是他们的要求比较严格,需要有一年的项目经验,所以我没有被选中。 后来陆续面试了几家公司,终于功夫不负有心人。我终于面试上的,是在闵行的一家民营的企业,公司规模比较小,我的职务是嵌入式linux应用开发,做安防产品的应用的。我想我也比较幸运,经理很看重我的努力,就决定录用我,开的工资是3500一个月,虽然我知道在上海3500只能过温饱的生活,但是我想我足够了。我至少不用每天都要靠父母养,我自己也能养活自己的。我想只要我继续努力,我工资一定会翻倍的。 把本文写出来,希望能让和我一样的没有基础的朋友有信心,其实我们没有必要自卑,我们不比别人笨,只要我们肯努力,我们一样会成功。

英语演讲稿 短一些 100至200个单词

As food is to the body, so is learning to the mind. Our bodies grow and muscles develop with the intake of adequate nutritious food. Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity. Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment. Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty.
Once learning stops, vegetation sets in. It is a common fallacy to regard school as the only workshop for the acquisition of knowledge. On the contrary, learning should be a never-ending process, from the cradle to the grave. With the world ever changing so fast, the cease from learning for just a few days will make a person lag behind. What's worse, the animalistic instinct dormant deep in our subconsciousness will come to life, weakening our will to pursue our noble ideal, sapping our determination to sweep away obstacles to our success and strangling our desire for the refinement of our character. Lack of learning will inevitably lead to the stagnation of the mind, or even worse, its fossilization, Therefore, to stay mentally young, we have to take learning as a lifelong career.
学习之于心灵,就像食物之于身体一样。摄取了适量的营养食物,我们的身体得以生长而肌肉得以发达。同样地,我们应该日复一日不断地学习以保持我们敏锐的心智能力,并扩充我们的智力容量。不断的学习提供我们用不尽的燃料,来驱使我们磨利我们的推理、分析和判断的能力。持续的学习是在信息时代中跟时代并驾齐驱的最稳当的方法,也是在变动的世代中成功的可靠保证。
一旦学习停止,单调贫乏的生活就开始了。视学校为汲取知识的唯一场所是种常见的谬误。相反地,学习应该是一种无终止的历程,从生到死。由于世界一直快速地在变动,只要学习停顿数日就将使人落后。更糟的是,蛰伏在我们潜意识深处的兽性本能就会复活,削弱我们追求高贵理想的意志,弱化我们扫除成功障碍的决心,而且扼杀我们净化我们人格的欲望。缺少学习将不可避免地导致心灵的停滞,甚至更糟地,使其僵化。因此,为了保持心理年轻,我们必须将学习当作一生的事业。
2.heavy schoolwork【课业繁重】
In my opinion, the schoolwork now being assigned to high school students is too heavy. While it is true that students need to study, they need other things as well if they are to grow into healthy and well-rounded adults. High should be allowed more time for play. Playing is not wasting time, as some think. It gives them physical exercise, and also exercise their imagination. Which tends to be stifled by too much study. Finally, the pressure put on high school students by excessive schoolwork can cause serious stress, which is unhealthy physically and mentally. I do not advocate the elimination of schoolwork. I do think, however, that a reduction of the current heavy load would be beneficial to students and to the society as a whole.
我认为目前高中生的课业实在太重了,虽然说学生的确应当念书,但是要想长大成为健全的人,他门还需要一些其它的东西,所以应该给高中生较多从事娱乐的时间。娱乐并不如某些人所想的,是在浪费时间,它可以让学生锻炼身体,发挥被繁重课业扼杀的想象力。此外,繁重的课业加诸在高中生身上的压力可能引起严重的情绪紧张,这对身心都有害。我并非主张废除学校课业,但是我认为减轻目前繁重的课业对于学生和整个社会都是有益的。
3.Time【时间】
Lost time is never found again. This is something which I learned very clearly last semester. I spent so much time fooling around that my grades began to suffer. I finally realized that something had to be done. It was time for a change.
Now I have a new plan for using my time wisely. I have set my alarm clock ahead half an hour. This will give me a head start on the day. I have also decided to keep a log of what I do and when I do it. Looking back on what I’ve done will give me some ideas on how to reorganize my time.
时光一去不复返,这是我上学期清楚学到的教训。我浪费很多时间四处游荡,以致于我的成绩开始退步。最后我终于了解到我必须有所作为;该是痛改前非的时候了。
现在我有一个明智运用时间的新方法。我已将闹钟早拨半小时,这将使我这一天的作息提前开始。我也决定将我所做的一切及做这些事的时间记录下来。回顾我所做的事情会启发我如何重新安排我的时间。
4.Work and Play【工作与娱乐】
Work and play do not contradict each other; in fact, they complement each other. As the saying goes, "All work and no play makes Jack a dull boy." A life burdened with work leads you nowhere, for you would get tired and bored with your daily routine work. On the other hand, proper recreation will relieve the tension and discomfort of our monotonous life because it offers you various ways to let out your pent-up emotions.
What I usually do to relax after school is jogging and seeing movies. Usually I don't spare time for exercise, but I value the physical education class at school. Jogging several rounds in the field certainly relieves the day's pressure. On weekends, I'll catch the morning movie for my visual enjoyment. I feel revived and energetic for another week's work-load.
工作与娱乐并不互相冲突,事实上,它们之间的关系还相辅相成。有句格言说:「整日工作而没有休闲娱乐,会令人变得沉闷乏味。」被工作重担压得喘不过气来的生活,将使你一事无成,因为你将对一成不变的例行公事感到厌烦。由另一方面来说,适度的娱乐活动能提供各种管道,来渲泄你被压抑的情绪,减轻单调生活中的紧张与不悦。
放学之后,我最常做的休闲活动,便是慢跑与看电影。通常我并不特地拨出时间来做运动,但是我很重视学校的体育课。在操场上慢跑几圈,无疑地可以减轻一天的压力。在周末时,我都去看早场电影,享受视觉飨宴。如此一来,我将有如再生般的充沛活力,去面对下一星期的工作量。
5.My first Job【我的第一份工作】
My first job was at a cramming school. It was three years ago when I just graduated from junior high school and finished the entrance examination. since I had nothing to do that summer, I decided to find a job, tasting the joy of independence.
I was responsible for answering the telephone and taking the message. I worked eight hours a day, six days a week. The work was not difficult nor heavy to me and I guess I did well. The most delighted thing was perhaps that I could spend the money I earned all by myself.
我的第一份工作是在一家补习班做事。那是三年前我刚从国中毕业,考完联考时的事了。既然我那整个夏天都闲着没事,倒不如找份差事,尝尝独立赚钱的快乐。
我负责接听电话且纪录留言的工作。我一天工作八小时,一星期工作六天。那份工作对我而言既不困难亦不沉重,所以我想我还满称职的。而最令人快乐的事大概莫过于花全部由自己赚来的钱了!
6.My Favorite Sports【我最喜爱的运动】
Sports help everyone to keep healthy, happy, and efficient. So I pay special attention to games, especially table-tennis. Table tennis is my favorite game. I play it almost every day.
Table-tennis is an ideal game us because it brings the whole body into action. It strengthens our muscles, expands our lungs, promotes the circulation of the blood, and causes a healthy action of the skin. Besides, it is very amusing and does not cost us much money. Table-tennis is very moderate; it is not so rough as football. It is an indoor game and can be played even on rainy days. Thus, it is my favorite kind of exercise.
运动能帮助每一个人保持健康、快乐和有效率。所以我特别重视运动,特别是桌球,桌球是我最喜欢的运动。我几乎每天玩。
桌球对我们而言,是一项理想的运动,因为它可以使我们全身运动,它可以增强我们的肌肉,扩张我们的肺部,促进血液循环,并且使肌肤产生健康作用,此外,它很有趣而且所费不多。桌球是相当温和适中的,它不像足球那么粗野。它是一种室内运动,甚至在下雨天也能玩。因此,桌球是我最喜爱的一种运动。



One day, a father and his little son were going home. At this age, the boy was interested in all kinds of things and was always asking questions. Now, he asked, "What's the meaning of the word 'Drunk', dad?" "Well, my son," his father replied, "look, there are standing two policemen. If I regard the two policemen as four then I am drunk."
"But, dad," the boy said, " there's only ONE policeman!"

醉酒

一天,父亲与小儿子一道回家。这个孩子正处于那种对什么事都很感兴趣的年龄,老是有提不完的问题。他向父亲发问道:“爸爸,‘醉’字是什么意思?” “唔,孩子,”父亲回答说,“你瞧那儿站着两个警察。如果我把他们看成了四个,那么我就算醉了。” “可是,爸爸, ”孩子说,“那儿只有一个警察呀!”
