基于汇编语言的MSP430单片机与上位机间串行通讯的实现

Implement of Serial Communication between MSP430 SCM and Upper Machine Based on Assembly Language

对MSP430单片机与上位机间串行通讯的硬软件进行了开发,其中,通过电平转换芯片LTC1385实现了单片机与上位机间的硬件连接,在定义的通讯协议的基础上,采用汇编语言开发出了单片机与上位机间串行通讯的程序。调试实验表明硬件设计与软件开发达到了预期的功能要求。

Hardware and software of serial communication between MSP430 SCM and upper machine were developed,in which,the hardware connection between SCM and upper machine was implemented through electrical level transfer chip LTC1385.And on the basis of the definition of communication protocol,programs of serial communication between SCM and upper machine were developed using assembly language.Debugging experiments indicate that hardware design and software development have attained the preplanned function requirements.
