Abstract: " Tian hua Cup " national electronic design and professional skills contest is by the ministry of industry and information talent exchange center held the national games, aiming at improving the college students of electronic systems design and debug related fields of study and research interest. Based on the " Tian hua Cup " competition, design a single-chip learning development board, this can be used to simulate " Tian hua Cup " competition, also can be used as a graduate student course design, design and manufacture of extracurricular technological motherboard. The smallest chip design dissertation system, keyboard, dial the code switch, LED display, LED lamp, A/D converter, D/A converter and power supply module circuit board, and in the study on the basis of an electric design simulation control system. Experiments show that this study board fully functional, simple structure, can satisfy our cup training and learning, chip has certain market prospect.
