摘要: 单片机技术是新工科背景下信息工程、机械类专业的重要课程,其相关技术被广泛应用于各行业领域中。单片机课程知识内容中,常用到的DMA(Direct memory access,直接内存访问)技术是一种外围设备与内存、内存与外围设备,或内存与内存之间在数据高速交换时不需要CPU(Central processing unit,中央处理器)参与的一种独特应用技术。在学生基础比较薄弱的地方性高校单片机课堂教学中,让学生熟悉掌握与运用该技术,有很大难度。单片机DMA技术的讲授需要教师对课堂教学内容有着精心的设计,该文以单片机型号STM32F103C8T6为例,设计了教学实验板,对DMA技术课程教学内容做适当的改革与尝试,同时将科学技术以课堂思政的形式引入了课堂。从实践效果上来看,取得了很好的课堂教学效果。

Abstract: Microcontroller technology is an important course for information engineering and mechanical majors under the background of new engineering. Its related technologies are widely used in various industries. In the knowledge content of the Microcontroller course, the commonly used DMA (Direct memory access) technology is a kind of peripheral equipment and memory, memory and peripheral equipment, or memory and memory when high-speed data exchange does not require CPU (Central Processing Unit) participates in a unique application technology. The explanation and teaching of DMA technology is very difficult for students to be familiar with and use the technology in the classroom of local colleges and universities where the student base is relatively weak. The teaching of DMA technology requires teachers to have a meticulous design of classroom teaching content. This article takes STM32F103C8T6 as an example, designs a teaching experiment board, and makes appropriate reforms and attempts to the teaching content of the DMA technology course, and introduces science and technology into the classroom in the form of Ideological and political education. From a practical point of view, classroom teaching has achieved good results.

Key words: Microcontroller technology, DMA technology, Digital tube drive, Teaching reform
