设计了由 80 31、 81 55、EPROM2 764、MAX2 32等组成的单片机实验板。结合硬件电路实验板可编写外部数据存储单元访问程序、程序存储单元查表程序、键盘扫描及显示程序、时间设定及计时程序 ,通过外部扩展还可衍生出对各种传感器信号的检测及控制 ,并和上位机通讯 ,实现远距离的监控 ,构成环境监控单元。实验由浅入深 ,使学生更好地掌握单片机软硬件的设计及调试技能 Designed by the 80 31, 81 55, EPROM2 764, MAX2 32 composed of single-chip experimental board. Combined with the hardware circuit board can write external data storage unit access program, program storage unit look-up program, keyboard scanning and display program, time setting and timing program, through the external expansion can also derive a variety of sensor signal detection and control , And communicate with the host computer to achieve long-distance monitoring, environmental monitoring unit. Experiments from shallow to deep, to enable students to better grasp the SCM hardware and software design and debugging skills
