摘要
51系列单片机教学实验板既是一块用户实验板,又是一种功能强大而实用的单片机开发调试工具。
它与传统的教学实验板相比有如下的优点:(1)价格低廉。(2)使用简单方便,只要有带RS232串口的PC机就能进行实验。(3)功能全,基本上具备单片机常用的接口,如数模转换、模数转换、存储器、LED数码管显示、键盘人机接口、并行接口、串行接口,等等。
采用本仿真开发实验板,可使初学者迅速掌握单片机原理及应用,熟悉汇编语言、甚至单片机C语言。用本仿真开发实验板,对用户源程序进行实时在线调试,可极大地缩短单片机应用系统的开发时间。

51 serial single chip processor teaching experiment board is a user experiment board, and also a powerful and practical single chip processor develop and debug tools.
Compared with traditional teaching experiment board it has following advantages :( 1) Cheap. (2) It is simple and convenient to use , so long as can carry on the experiment with a PC with RS232. ( 3) With complete function, possess the common user interface of the basic single chip processor, the ADC block, the DAC block, the memory , HID(Human Interface Device, such as the LED and the key board) , parallel interface, serial interface , and so on.
With this experiment board, the beginners can easily to grasp the principle and application of the Monolithic integrated circuit ,be familiar with assemble languages , even the C51 languages. The character of on system debug can shorten the time to study Develop experiment board with emulation this, carry on to user source program real-time to debug online, can shorten construction period of the application system of the single chip processor greatly.
Key words: single chip processor; experiment board; interface; assemble languages
