摘要
根据嵌入式系统课程所持有的嵌入式系统教学实验板数量不足、实践教学内容不够完善等问题,开发了新一代的嵌入式系统教学实验板。该教学实验板以基于ARM926EJ-S内核的AT91SAM9G45处理器和嵌入式Linux操作系统(版本2.6.30)为平台,扩展了SDRAM、NAND Flash、以太网物理层芯片,新增扩展了SPI、TWI、SSC等常用串行总线,丰富了音频ADC/DAC、RTC、EEPROM、TS、7段LED、SD卡等外设;开发了相关的实验例程,编写了完整的实验指导书,配备了含有相关资料的DVD光盘、必要的连接线缆、工具盒,组成了完整的嵌入式系统教学实验板学习套件。所开发的教学实验板已经批量生产了62套,并全部投入实践教学中,有效地解决了原有教学设备数量不足及实验内容不完善的问题,节约了教学投入经费,节省了实验室空间,为学生深入学习嵌入式技术提供了实践平台。
The ARM-Linux teaching experimental kit was developed to overcome the shortage of original ARM teaching experimental kit and deficient practical teaching contents in the Embedded Systems course of our college. Based on ATglSAM9G45 with the ARM926EJ-S kernel, and Linux 2. 6. 13 operating system transplantation, the new teaching experimental kit has been improved in several aspects. SDRAM, NAND FLASH and Ethernet PHY were extended. SPI, TWI, SSC interface were extracted. Some peripherals were enriched including audio ADC/DAC, RTC, EEPROM, 7-Segment LED, SD card, etc. Relative experiment examples were developed and the experimental instruction book was edited. Learning package was completed with DVD, necessary connection cables and tools box. Sixty-two teaching experimental kits have been produced and are in service for practical teaching, which can effectively solve the insufficient number of teaching facilities and incomplete experimental contents. Thus, the teaching funds were retrenched and the occupied space was greatly saved. Moreover, the teaching experimental kits provide a practical platform for students to learn more about the embedded technology.
