Design Of High Performance Price Ratio Teaching Experiment System Based On ARM7

In the recent years, with the rapid technological developments and the corresponding rise in the range of diverse applications of embeded technology, courses on embeded systems are giving by more and more universities. In the same time, many universities are attaching more importance to the teaching and experiment platform of embedded system.This dissertation has analysed the current situation of present university's experiment teaching at first, then carried on the exploration of the study effient problem ,and finally proposed the concrete experimental teaching solution: High performance price ratio teaching experiment system based on ARM7 is developed from the chip level, which reasonably using resources to build a high performance price ratio system platform,and compiling the massive teaching experiment in this platform.These experiment pointed strong, level clear, and is also easy to study , imitationand and developed.The dissertation carries on from following three parts:System platform design: This dissertation chooses a widely used ARM7TDMI processor chip with lower price and simple structure, develops its periphery interface function according to the processor speciality to support for the experiment. These periphery interfaces include: LCD, Bottons, LED, I2C, UART, SPI, and JTAG for simulation and debugging. As well as debugging software, real-timeoperating system, and some APIs. Foundation experiment: The experimental teaching is the most important design part in this dissertation. This part has developed three levels experiments. But the first two levels experiment belongs to the foundation teaching experiment. The first level experiments without operating system are based on the different module in the hardware platform. The second level teaching experiments are developed for the embedded real-time OS teaching.Comprehensive experiment: The last level teaching experiment, this part of experiments using the knowledge learned before for developing an application project: Real-time alarm system.This dissertation makes full advantage of the virtue of embeded system no matter on theory or in practice, and completely designs and develops of the embeded teaching system. Not only completedthe system hardware design and the printed wiring board manufacture, has compiled teaching PPT, but also realized all experiments.
