摘　　要：应用单片机微型智能系统对输出数据:电压、电流及电位的采集测量、显示和打印。以8031单片机为核心,8031单片机有一个8位的CPU,一个128字节的RAM,21个特殊功能寄存器,4个8位并行I/O口,1个全双工异步串行端口,2个16位定时器/计数器,5个具有优先级别的中断源。在8031外接一片程序存储器就可以构成一个有完整功能的微机应用电路。MCU intelligent system is used to collect, measure, display, and print output data： voltage, current, and potential, with 8031 MCU as the core. the 8031 has a 8 bits of CPU, a 128 bytes of RAM, and a special functions registers, four 8bit parallel I/O port, a full-duplex asynchronous serial port, two 16bit timer/counter, five interrupt sources having priority level. It only needs externally connecting a program memory on 8031, can a microcomputer application circuit having complete function be constructed.
