摘要
介绍了单片机数据采集系统的硬件原理和软件设计。该系统以 89C5 1单片机为核心 ,以 12位TLC2 5 43为串行模数转换器 ,由MC14 4 89构成采集数据实时显示系统 ,带有RS 2 32通信接口 ,系统具有易实现、易编程、可移植、体积小、功耗低等优点 。
The paper introduces the hardware principle and the software design of the MCU data acquisition system based on 89C51 , in which the 12 bit TLC2543 acts as the serial A/D converter and the RS 232 as the communication interface , and the real time displaying system is constructed by MC14489. The system has the advantages of easily realize , program and transplant , and it has the small volume and low power, etc.. It is therefore very promising and valuable.
