温控型非易失性数字电位器DS1847(8)智能接口的设计与其在测量中的应用

The Design of the Interfaces for the Temperature - Controlled Nonvolatile(NV) Variable Resistor DS1847(8) and Its Application in Measurement

本文设计了温控电位器DSl847(8)智能接口,采用80c552单片机及C51编程技术,使该接口可方便的作为计算机系统的外设使用,上级计算机系统可以通过并行接口或RS-232接口方便对电位器进行操作。文中还介绍了该电位器在温差测量系统的应用。最后给出了使用该电位器的一些建议。

Based on the micro - chip processor 80c552, the interfaces of the Temperature - Controlled Nonvolatile (MO Variable Resistor DS1417(8) have been designed and worked out. It makes Ds 1417(8) easyto connect with PC and other devices via serial interface and parallel interface, Moreover, its application in measurement has beenintroduced, too .At end, some aduses were given.
