The purpose of this study is to develop new experiment theme for students to aid understanding Operating-System(OS). In the "Computer-Engineering-Course" of "the Department of Production Systems Engineering", we teach about the OS. For the experiment of Computer-Engineering-Course, we have been using small computer reference-board which embedded Real-Time OS (T-kernel 2.0). This reference-board has LCD-panel(800x480pixcels) with touch panel, GPIO(4bit) for general purpose input/output, push-switch for hardware-interrupt. The "T-kernel" is the newest version of TRON OS, and it has been used in many embed-systems. To develop an application system with the T-kernel, it is necessary to study multi-task-programming, interrupt processing and task-to-task communication. We developed motor-control-system which used touch-panel, GPIO port and push-switch. By touching LCD-panel or push-switch, it will change display image, the motor will turn on or turn off. Moreover, the motor has 4 status; turning clockwise, turning counterclockwise, stopping, and idling. We can choose one from them. By using this experimental tools, we expect that it is helpful for students to learn about OS through lecture and experiment.
