An Experiment And Training System Based On STC89 MCU

As an important section of MCU teaching, experimentation can improve the practice and innovation ability of students, enhance their all-around development. But the training effect isn't satisfying presently due to lacking of appropriate experiment equipment; the emulator can't prevail for its high price and the low-cost board based on monitor program only has simplex function. So a new experiment and training system based on STC89 MCU is designed, which can realize the main function of emulator with low-cost. Students can expediently master assemble language and C language with help of the teaching system.Main completed tasks in the paper:1. We primarily analyze the actuality of experiment equipment; then introduced a project based on ISP and monitor program technique. The new system integrated ISP function, programmer, emulator and experimental broad with a low price.2. Not only we achieved all hardware and software tasks, but also introduced a virtual MCU emulate platform which is based on Proteus and Keil. The emulate platform can train students practice before the hardware operation, and then the difficulty for fresher is reduced and learning efficiency is improved.3. Some integrative and innovative experiments were designed, including automobile supervising alarm, intelligent path- recognize vehicle and so on. The new experiments can widen students'view; enhance their ability in MCU application.All hardware and software tasks have been completed by now and the experimental board is in production. The tryout effect in small range is well.
