摘要
设计了以ARM LPC2148 MCU为核心的ARM嵌入式系统课程教学辅助系统。系统硬件设计包含了最小系统、串行通信及程序下载接口电路,矩阵键盘和可以用作中断输入的独立按键、字符和点阵LCD等组成的输入/输出人机界面接口;软件设计配备了系统的教学例程、完整的Proteus电路原理图和相关硬件模块的应用程序包。实践证明,该教辅系统对嵌入式系统课程的课堂教学、实验教学以及学生课外竞赛科研等都起到了很好的辅助作用,能很好地帮助学生学习掌握嵌入式系统的应用开发技术,并有助于学生自主学习能力和工程素质的培养。
This paper introduces a teaching assistant system for ARM embedded system course based on ARM LPC2148 MCU.The system hardware design includes the minimum system, the serial communication and program download interface circuits, the matrix-keyboard and the independent keys used as the interrupt input, and the character LCD and dot-matrix LCD interface. The software design includes the standard project template of ARM embedded system, complete Proteus circuit schematic and the application package for the related hardware modules. Proved by the teaching practice, the teaching assistant system plays a good supporting role in the classroom teaching of embedded system courses, and in the experiment and practice training of embedded system courses, and in the students＇ extracurricular scientific researching. It also effectively helps students learning to master the technology of embedded system, and helps to the students＇ autonomous learning ability and engineering quality training.
