【摘要】 主要介绍基于MODBUS协议的PC机与DSP串口通信软件的设计和实现方法。该系统以PC机作为上位机,TMS320VC33DSP作为下位机,采用中断方式实现数据的接收和发送。实验结果表明:软件能保证数据传输的可靠性,并实现了智能温度控制系统中上位机与下位机之间的主从式通信。更多还原

【Abstract】 The design and implementation method of the serial communication software for personal computer(PC) and digital signal process(DSP) based on MODBUS protocol is presented,which is used in the intelligent temperature monitoring system.This system takes PC as the host computer and TMS320VC33 as the lower computer,and interruption mode to receive and transmit data.The experimental results show that the software can realize the data transmission between the host and lower computer reliably.更多还原
