Abstract: The matrix LED experiment is an important project for Introduction to Embedded System. By set up course contents at several levels and effective interaction between student and teacher in this elaborate experimental project, most undergraduates would develop innovative thinking and practical skills. By well-designed course contents, interaction and innovative guidance of self-designed experiments, this course helps the students extend their cognition and thinking, to guide and develop their innovation ability, and therefore, students could accomplish their self-designed experiments based on fundamental experiment. According to the feedback of four years teaching practice, this experimental item has received satisfying results in undergraduate practical and creative ability training.
Key words: matrix LED experiment; practical and innovative ability guidance; embedded system
本矩陣LED實(shí)驗(yàn)項(xiàng)目基于EmbestEduKit-IV(選用S3C2410處理器子板)教學(xué)實(shí)驗(yàn)平臺(tái),所有的實(shí)例代碼均在該教學(xué)實(shí)驗(yàn)平臺(tái)上運(yùn)行通過(guò)。
矩陣LED實(shí)驗(yàn)是與《嵌入式系統(tǒng)導(dǎo)論》課程配套的一個(gè)綜合性實(shí)驗(yàn)項(xiàng)目,是整個(gè)嵌入式系統(tǒng)導(dǎo)論實(shí)驗(yàn)課程中的一個(gè)焦點(diǎn)和亮點(diǎn)。實(shí)驗(yàn)著重于培養(yǎng)學(xué)生的動(dòng)手能力和嵌入式開(kāi)發(fā)平臺(tái)的基本應(yīng)用技能,使學(xué)生理解嵌入式系統(tǒng)和嵌入式軟件的特點(diǎn),掌握嵌入式軟件開(kāi)發(fā)的基本特點(diǎn)、基本流程和基本方法。
實(shí)驗(yàn)的設(shè)計(jì)目標(biāo)是培養(yǎng)學(xué)生綜合運(yùn)用知識(shí)能力、實(shí)踐能力和創(chuàng)新意識(shí)。整體上,考慮到嵌入式系統(tǒng)實(shí)驗(yàn)要求知識(shí)的多面性與綜合性,根據(jù)因材施教的教學(xué)原則,采用由基礎(chǔ)實(shí)驗(yàn)設(shè)計(jì)到高級(jí)實(shí)驗(yàn)拓展的分級(jí)設(shè)計(jì)思想。
