TMS320C32与PC机数据通信系统的开发与研究

Development and Research of Data Communication System between TMS320C32 and PC

本文基于TI公司的浮点运算DSP芯片TMS320C32,介绍了DSP芯片及其与PC机串行数据通信的特点,分别给出了DSP与PC机数据通信系统的上下位机开发方法。且阐述了采用Windows多线程技术开发的上位机软件的基本结构和以Am85c30通信芯片为核心的下位机通信适配器硬件设计。并以自行开发的基于DSP的电动机智能保护系统中TMS320C32与PC机的串行数据通信部分开发为例,详细介绍了系统的结构及几大功能的实现。

Based on the float operation DSP made in Tl copporation.This paper introduces the character of DSP and serial communication,gives a easy way of using mutli-thread to develop Serial Communication between DSP and PC system ,Combining with the example of the serial communication module in our intellectual protecting system for electromotor based DSP. the author introduces the structure of our system and how to perform the main functions.
