在线调试与编程的单片机教学实验板设计

针对目前高校学生单片机设计训练不足、应用能力低下的现状，设计了一种支持在线调试与编程的教学实验板。该板以SST系列51兼容型单片机为核心，最大限度利用其片上资源，并在外围配置了LED数码管、LCD点阵显示器、蜂呜器、行列键盘、功率驱动电路、数字温度传感器、红外收发器及多种I^2C器件，具有体积小、成本低、可靠性高、可扩展性强等优点。除用于实验教学外，也可作为课程设计、毕业设计、课外电子设计等方面的通用开发板。通过大量案例学习和任务驱动训练，可使学生的应用设计能力得到快速、有效的提高。文章还具体阐述了实验板的总体设计思想、硬件实现与实际应用。

Design of a MCU Demonstration and Development Board with IAP and ICE Function

Owing to the fact that insufficient design exercises on Microcontroller Unit (MCU) result in university students' weak practical ability,a demonstration board with In-Application Programming (IAP) and ln-Circuit Emulation(ICE) features is specially proposed and practically realized.The hardware of the board is composed of SST 51-core MCU and some frequently used peripherals including 7-segment LED display, dot-matrix LCD module,piezoelectric buzzer, 16-button matrix keyboard,dual full-bridge power driver,1- wire digital thermometer.infrared transceiver module and some popular I2C bus devices.It exhibits many advantages such as low cost, small mechanical size,high reliability and system extensibility.Besides experiment teaching,it could also be used as the development board for course projects,graduation projects or extracurricular projects related to microcontroller.Combined with case-based learning and task-driven training methods,students' actual capability can be greatly improved.The global design idea,hardware implementation and practical application of the board are described in detail.
