基于XMODEM协议的在板文件下载软件设计

Design of File Download Program in System Board on XMODEM Protocol

本文描述了使用XMODEM文件传输协议的通信程序设计,该设计为具有FLASHMEMORY存储器的嵌入式系统提供了和PC机上超级终端软件之间的文件传输功能,在PC机上不安装专用通信软件的情况下,实现程序的在板升级、数据在板定制等,给现场调试和维护带来方便。另外,本文也描述了基于状态矩阵的通信软件编程方法。

This paper describes communication programming design using the XMODEM file transmission protocol. The design is used to realize the function of file transmission between embedded system with flash memory and PC. Under the PC does not install special communication software, program upgrade and data customization is easy realized. It is very convenient that program is debugged and maintained on system board. Besides, a communication programming method is designed on state matrix in this paper.
