一种简单的光电隔离RS-232电平转换接口设计
A kind of simple photoelectric-isolated RS-232 voltage conversion interface design
摘要
Abstract
A design method of a kind of practical photoelectric-isolated RS-232 voltage conversion interface is introduced .Making use of the method ,a connection circuit is designed, which does not need RS-232 voltage converter and fulfills voltage conversion by photoelectric coupler directly. At the same time, hardware connection circuit,complete communication protocols and software design of communication between MCS-51 single-chip microcomputer and PC computer are given.关键词
