Arm-based Embedded Wireless Communication Experiment Design

The experiment object is a very impotent course in Technical University. With the developing of the micro electric and the education theory, how to teach both in knowledge and in practice, how to create a new model of experiment and how to build a top experiment base become a very urgent problem and need to be solved quickly. ARM7TDMI microprocessor has the advantages of low-power, cost-effictive and high performance, supporting many kinds of interface and operation system .According to these outstanding advantages, this paper uses the Samsung S3C44B0X microprocessor as the core to build an embedded experiment plat form. At the same time we chose siemens MC35IT with RS232 interface as the wireless network accessing device to work with the experiment developing board. And these two devices form the whole embedded wireless communication experiment system. We have finished confining and debugging the hardware to make this system work. This embedded experiment system has these advantages: cost-effective and high performance, easy to maintain and upgrade, easy to explore new experiment area. Meanwhile this experiment system not only fit the demand of nowadays experiment well but also can go with the developing of electronic science and work well. Base the hardware plat form of this experiment system, we design 3 open experiment projects to face the high grand batchers and masters. They are: Boot Loader design, uClinux kernel image and ROMFS file system image making, SMS and audio communication program design. We list the aim of experiment, the support theory and the function demand of the experiment. We also design the project from top to details as the assistant document. These projects take the market as the guide and base the information integration to put creative developing, plan making and flow design together into one experiment. And effectively improve the level of experiment teaching. Also these open means of experiment, stimulate the participator's passion and give them the space of creation. During the experiment not only the participator's technical ability has been improved but also their ability of project management and organization. Using the theory of market and teamwork which comes from product integration and developing in experiment design has very active mean in exploring our sight of view.
