Embedded Systems Programming Instruction using a Virtual Testbed

计算机科学（31）本项目开发了一个虚拟测试平台，允许提供实践经验，以大量的学生一起的课程材料，为嵌入式系统编程的入门课程。其关键特征是将PC与嵌入式处理器板耦合，并模拟各种外部机电设备，从而减轻了提供大量昂贵、易于维护的物理设备的需求。嵌入式处理器上运行的用户程序对设备的请求被透明地转发到PC上的模拟器。使用软件仪器，如电压表和示波器，学生体验动手编程，而该机构体验低成本低维护的实验室。正在开发的课程材料适用于嵌入式系统编程的入门课程，由一系列模块组成，每个模块都以一个小型编程项目为中心。所有材料都以网络为基础，以便广泛传播和可能的远程学习。

Computer Science (31)This project develops a virtual testbed that allows for providing hands-on experience to large numbers of students together with the course material for an introductory course on embedded systems programming. The key feature is to couple a PC with an embedded processor board and to simulate a variety of external electromechanical devices thereby alleviating the need to provide expensive, maintenance prone physical devices in large numbers. Requests of devices by user programs running on the embedded processor are transparently forwarded to the simulators on the PC. Using software instruments such as voltmeters and scopes, students experience hands-on programming while the institution experiences a low-cost low-maintenance laboratory.The course material being developed applies to an introductory course in embedded systems programming and consists of a sequence of modules, each of which is centered on a small programming project. All materials are web-based to allow for broad dissemination and possible distance learning.
