发展历史

单片机(Microcontrollers)诞生于1971年,经历了SCM、MCU、SoC三大阶段,早期的SCM单片机都是8位或4位的。其中最成功的是INTEL的8051,此后在8051上发展出了MCS51系列MCU系统。基于这一系统的单片机系统直到现在还在广泛使用。随着工业控制领域要求的提高,开始出现了16位单片机,但因为性价比不理想并未得到很广泛的应用。90年代后随着消费电子产品大发展,单片机技术得到了巨大提高。随着INTEL i960系列特别是后来的ARM系列的广泛应用,32位单片机迅速取代16位单片机的高端地位,并且进入主流市场。

而传统的8位单片机的性能也得到了飞速提高,处理能力比起80年代提高了数百倍。高端的32位Soc单片机主频已经超过300MHz,性能直追90年代中期的专用处理器,而普通的型号出厂价格跌落至1美元,最高端的型号也只有10美元。

当代单片机系统已经不再只在裸机环境下开发和使用,大量专用的嵌入式操作系统被广泛应用在全系列的单片机上。而在作为掌上电脑和手机核心处理的高端单片机甚至可以直接使用专用的Windows和Linux操作系统。

主要阶段

早期阶段

SCM即单片微型计算机(Microcontrollers)阶段,主要是寻求最佳的单片形态嵌入式系统的最佳体系结构。“创新模式”获得成功,奠定了SCM与通用计算机完全不同的发展道路。在开创嵌入式系统独立发展道路上,Intel公司功不可没。

中期发展

MCU即微控制器(Micro Controller Unit)阶段,主要的技术发展方向是:不断扩展满足嵌入式应用时,对象系统要求的各种外围电路与接口电路,突显其对象的智能化控制能力。它所涉及的领域都与对象系统相关,因此,发展MCU的重任不可避免地落在电气、电子技术厂家。从这一角度来看,Intel逐渐淡出MCU的发展也有其客观因素。在发展MCU方面,最著名的厂家当数Philips公司。

Philips公司以其在嵌入式应用方面的巨大优势,将MCS-51从单片微型计算机迅速发展到微控制器。因此,当我们回顾嵌入式系统发展道路时,不要忘记Intel和Philips的历史功绩。

当前趋势

SoC嵌入式系统(System on Chip)式的独立发展之路,向MCU阶段发展的重要因素,就是寻求应用系统在芯片上的最大化解决,因此,专用单片机的发展自然形成了SoC化趋势。随着微电子技术、IC设计、EDA工具的发展,基于SoC的单片机应用系统设计会有较大的发展。因此,对单片机的理解可以从单片微型计算机、单片微控制器延伸到单片应用系统。

早期发展

1971年intel公司研制出世界上第一个4位的微处理器;Intel公司的霍夫研制成功世界上第一块4位微处理器芯片Intel 4004,标志着第一代微处理器问世,微处理器和微机时代从此开始。因发明微处理器,霍夫被英国《经济学家》杂志列为“二战以来最有影响力的`7位科学家”之一。

1971年11月,Intel推出MCS-4微型计算机系统(包括4001 ROM芯片、4002 RAM芯片、4003移位寄存器芯片和4004微处理器)其中4004(下图)包含2300个晶体管,尺寸规格为3mm×4mm,计算性能远远超过当年的ENIAC,最初售价为200美元。

1972年4月,霍夫等人开发出第一个8位微处理器Intel 8008。由于8008采用的是P沟道MOS微处理器,因此仍属第一代微处理器。

1973年intel公司研制出8位的微处理器8080;1973年8月,霍夫等人研制出8位微处理器Intel 8080,以N沟道MOS电路取代了P沟道,第二代微处理器就此诞生。

主频2MHz的8080芯片运算速度比8008快10倍,可存取64KB存储器,使用了基于6微米技术的6000个晶体管,处理速度为(Million Instructions Per Second )。

1975年4月,MITS发布第一个通用型Altair 8800,售价375美元,带有1KB存储器。这是世界上第一台微型计算机。

1976年intel公司研制出MCS-48系列8位的单片机,这也是单片机的问世。

Zilog公司于1976年开发的Z80微处理器,广泛用于微型计算机和工业自动控制设备。当时,Zilog、Motorola和Intel在微处理器领域三足鼎立。

20世纪80年代初,Intel公司在MCS-48系列单片机的基础上,推出了MCS-51系列8位高档单片机。MCS-51系列单片机无论是片内RAM容量,I/O口功能,系统扩展方面都有了很大的提高。

【摘要】

过去的以教师为中心的单片机课程教学,由于课程的综合性太强使得学生在学习过程中对很多知识点难以接受,我们通过对本门课程项目式和模块化改革的结合,合理安排教学内容和教学资源,降低初学者入门门槛,引导学生以兴趣为导向,极大的提高了学习者主动获取知识的意愿,明显提高了本课程的教学效果。

【关键词】 模块化教学;项目驱动;教学改革

“单片机技术”课程在本科院校里是电子信息类专业的必修课程,这门课程是以电子技术基础,编程语言,计算机理论等知识为基础的一门专业性和应用性很强的综合性课程。基于以上特点,对于初学者来说对单片机的理论知识的正确把握往往感觉比较吃力,给初学者造成学习困难。但是经过我们多年的教学经验,这类有很强的应用性和实用性的课程,以项目式教学更能推动学生的学习兴趣,同时模块化的教学设计更能降低初学者入门的门槛。两者相结合教学方法的采用对本门课程的教学效果提升明显.

1、单片机项目驱动教学法

以往的单片机教学模式是以教师为中心,老师在课堂上按照教材,或者教学大纲按部就班的讲授理论原理和知识点;以课堂教学为中心,学生学习为被动接受,由于知识点综合性比较强,理论太深奥使得学生往往学习兴趣不高,同时缺乏动手实践机会,教学效果一般不够理想。以项目驱动的教学法是学生为主体,教师为主导,以实践应用为根本目标,围绕具体的项目构建教学内容体系,通过师生共同参与完成一个具体的项目而展开的教学活动。注重的不是最终的结果,而是项目完成的过程,在项目的教学实施过程中,学生按需学习,亲身实践,学生在项目的实践过程中,理解知识和掌握技能,学习成为一个参与的创造实践活动,培养分析和解决问题的能力。引进单片机项目教学方式打破了原有的教学组织安排,以项目的开发步骤作为教学内容,将课程的内容分解为一个个小项目,从项目引入到项目解析再到任务分解然后到知识点讲解最后知识点应用,将原教学方案里单片机的知识点穿插到具体项目开发的过程中。这里面包含了软、硬平台搭建到项目展开再到项目完成的一系列教学活动,使学生从被动学习变为主动学习,按照这种方法我们将以往教学体系中的知识内容变化为若干个工程项目,然后围绕着这些工程项目任务的展开同时开展教学,让学生以具体工作目标的展开来进行教学环节的工作。有利于激发学生的学习积极性和创新能力,调动了学生的学习积极性。在这整个过程中,学生能很好的把握课程的知识要求,在体验创新与探索的过程中,又培养了学生们的分析解决问题的能力及团队协作能力等。

2、模块化的单片机教学方法

任何复杂的系统都是由具有完整基本功能的功能模块电路组成,单片机应用系统也是如此,一般由cpu系统、中断系统、I/O口等。同时任何复杂的电路系统都可以分解为多个具备单一功能的模块电路,按照这个思路,学习单片机系统我们也可以从单片机的功能模块电路入手,我们根据学生的认知规律,和学习单片的一般原理的方法,机将单片机教学模块分成几个部分,这里面每个部分有自己的专用模块[3]。比如程序功能部分、硬件部分;在对硬件电路设计部分进行模块化设计,将单片机的各个功能模块以独立的原理图形式出现,我们把单片机个硬件按功能分为了键盘模块、数码管显示模块、传感器控制模块、模数转换模块、显示模块、通信模块等几大模块,如图1。各个模块通过面包板上预留的连接器与系统主板进行连接,然后用排线组合成所需要的系统。在教学过程中,要不断收集遇到的各种硬件功能模块电路,弄清它们的工作原理、性能及特性、特定的功能及使用方法,把系统化整为零,建立起自己的硬件模块库。指导学生学会搜集、分析别人的设计案例、论文和相关书籍中的功能模块电路,不断地充实自己的功能模块电路库,日积月累,学生就会觉得自己的单片机系统设计能力越来越强。最后在进行模块分解时,各模块功能尽可能专一,联系尽可能简单,使模块独立性强,方便教学实用的模块。

3、总结

新兴本院校定位应用型教学型高校,以培应用型、创新型人才为目标。在此基础上的以项目驱动法教学和模块化教学为主线,以实际应用为培养为目标的“单片机技术”课程教学改革思路,按照这个方式能使学生在项目模块化的环节中一步一个台阶。此教学法脱离了枯燥无味的说教模式,使学生在具体的设计项目的工作环境里轻松自在的状态来投入到学习中,思维能力、动手能力、学习能力以及团队协作能力都有了明显提高,模块化学习过程中所积累的各种电路系统模块也促进构建成学生进行科技创新实践、参加大学生创新创业训练的重要模块库,激发了学生学习的主动性和成就感。法国文化教育学家斯普朗格曾言:教育的最终目的不是传授已有的东西,而是要把人的创造力量诱导出来。本课程的教学改革正是朝着这个方向前进。

Field of the Invention The present invention relates to a 2-in-1 card-insertion type memory card adapter, and especially to an adapter for converting a Mini SD card or a Micro SD card to have the specification for connecting suiting an SD card after insertion of the Mini SD card or the Micro SD card. 2. Description of the Prior Art Memory cards in the markets nowadays have numerous kinds, and memory cards of various brands have different sizes, this renders users to have to purchase compatible electric products in use in order to allow the memory cards to be used commonly with them. However, among various memory cards, some are used by the identical reading mode, for instance, Mini SD cards, Micro SD cards and SD cards all are commonly used in the reading mode, they are different only in size; there have been many "Mini SD-converting into-SD adapters" in the markets to convert a Mini SD card to have the specification for connecting suiting an SD card, with which the Mini SD card can be connected through a "Mini SD-converting into-SD adapter" and applied in an electronic product that can only read an SD card. Alternatively, there have been "Micro SD-converting into-SD adapters" in the markets to convert a Micro SD card to have the specification for connecting suiting an SD card, with which the Micro SD card can be transferred through a "Mini SD-converting into-SD adapter" to be applied in electronic products that can only read an SD card. However, when portable electronic products that can be carried on users' persons, for instance, PDAs, mobile phones, mobile albums, computers etc. are used to do data, image or sound access, if their specifications for connecting suit SD cards, a "Mini SD-converting into-SD adapter" or a "Micro SD-converting into-SD adapter" are often used to do connecting for Mini SD cards or Micro SD cards, so that data can be up loaded or down loaded. For a consumer, when in use, he must purchase two kinds of adapters (a "Mini SD-converting into-SD adapter" and a "Micro SD-converting into-SD adapter") for specification converting. In other words, this may induce inconvenience for a user in carrying, and is subjected to making confusing in use. SUMMARY OF THE INVENTION In view of the problems resided in the technique of the prior art, the main purpose of the present invention is to design a 2-in-1 card-insertion type memory card adapter that renders a Mini SD card or a Micro SD card to connect to an electric product having an SD card insertion port through connecting of the adapter. The 2-in-1 card-insertion type memory card adapter of the present invention is in coincidence with the size of an SD card and the specification for connecting of the SD card to convert one of a Mini SD card and a Micro SD card. The adapter comprises at least a housing, a base plate with pins and a positioning rack. Wherein the housing meets the size of an SD card, it is provided on its front end with a plurality of windows for a plurality of electric conducting sheets having at their rear end a fitting groove meeting the size of a Mini SD card for positioning the card after insertion; the base plate with pins is provided in the housing, the electric conducting sheets are provided in opposition to the windows for the electric conducting sheets which meet the specification for connecting of the SD card; the base plate has thereon a first pin set and a second pin set, the first pin set and the second pin set are electrically connected with the electric conducting sheets; and the base plate can be provided with a plurality of holes, a lower lid is provided thereon with a plurality of studs to be molded in opposition to the holes and to be abutted against an inner lid. When a Mini SD card is inserted in the fitting groove for positioning, the first pin set is exactly connected with the Mini SD card; The above mentioned positioning rack meets the size of a Mini SD card, and is provided thereon with a positioning portion for positioning of the Mini SD card; when the positioning rack is inserted in the fitting groove for positioning, the second pin set can be exactly connected with a Micro SD card; when it is desired to have the Micro SD card positioned in the 2-in-1 card-insertion type memory card adapter, the Micro SD card shall be inserted in the positioning rack for positioning firstly, then the positioning rack having the Micro SD card positioned therein is inserted in the fitting groove, thus the Micro SD card is indirectly positioned in the fitting groove to be connected with the second pin set.
