| The subject develops a kind of modern electronic teaching platform based on wide touch screen, and the platform system is mainly for teaching.In the system design, Ml speed USB interface is used to connect teaching platform and computer, which ensures real-time and accurate data transmission, and also realize the PnP function of the platform. The technique of the wide touch screen, which could realize electronical teaching, can enable the teaching platform to replace the conventional blackboard. The driver and the application software, developed with Microsoft DDK, VC++ and VB respectively, make the system possesses good performance, which is also in favor of the software upgrading.The whole system design scheme is given in the paper, and the detailed design of the system hardware, the Firmware, the driver, as well as the application software altogether are discussed. Finally, the system is debugged. Experiment results show that the system design is valid. |
