基于TMS320LF2407的变频器串行通信设计

摘要

This paper introduces the Modbus protocol and uses assembly language to realize the RTU mode programming based on Modbus in TMS320 LF2407 inverter. The key procedures in the design are analyzed and discussed, and the feasibility of the project is verified by building a hardware platform in the laboratory, and the serial communication and control functions of the host computer and the frequency converter are realized.%介绍了Modbus串行通信协议的原理, 并在TMS320LF2407变频器控制模块上采用汇编语言实现基于Modbus的RTU模式程序编写.重点对设计中的关键程序进行了分析和探讨, 并通过在实验室搭建硬件平台, 验证了项目的可行性, 实现了上位机和变频器的串行通信及控制功能.
