【摘要】：随着电子技术的发展，在工业控制，智能仪表，外设控制，家用电器，机器人等方面取得了广泛的运用。曾有人这样说，世界每卖出一个汉堡，就卖出一个单片机。这样，在工厂和学校中学习单片机的人越来越多。为了帮助使用者更好的学习单片机，能够自己动手编写程序，特设计了一个多功能用户实验板。本电路板适用于那些单片机的爱好者在上机编程时使用。这对于开发实验活动具有较高价值。对于这个实验板的要求是：价格相对比较低廉，，能够很好的把课堂上学习的内容与实验结合起来。基于以上要求，设计的电路板主要有以下几个部分构成：直流电源，单片机最小系统，复位电路，键盘和LED显示接口电路，A/D转换接口电路，D/A转换接口电路，RS-232接口电路等。
[Abstract]:With the development of electronic technology, it has been widely used in industrial control, intelligent instruments, peripheral control, household appliances, robots and so on. Some people once said that for every hamburger sold in the world, a single chip computer is sold. More and more people are studying SCM in factories and schools. In order to help the users to learn SCM better, they can write their own programs. A multifunctional user experiment board is specially designed. The circuit board is suitable for those single-chip computer enthusiasts to use in computer programming. This is of great value for the development of experimental activities. The requirements of the experiment board are that the price is relatively low, and the content learned in the classroom can be well combined with the experiment. Based on the above requirements, the circuit board is composed of the following parts: DC power supply, microcontroller minimum system, reset circuit, keyboard and LED display interface circuit, A / D conversion interface circuit and RS-232 interface circuit, etc.
