基于MiniGUI键盘输入的通用网络接口的设计

摘要

在分析了MiniGUI系统架构的基础上,设计了通用的键盘网络接口通信协议以及该网络化接口在嵌入式Linux和MiniGUI下的实现.采用UDP作为网络承载协议,控制端遵照网络键盘协议发UDP包到MiniGUI网络键盘接口,即可实现MiniGUl键盘输入.根据具体按键布局需求,更改网络接口的键盘映射码,可满足不同的键盘指令控制场合,同时该网络接口也可扩展到局域网和广城网上实现远程控制.%On the basis of analyzing MiniGUI system architecture, the universal keyboard network interface communication protocol is designed and the network interface is realized in the embedded Linux and MiniGUI environment.UDP is adopted as the network load protocols, and the control terminal sends UDP packets to the MiniGUI network keyboard interface.Then, the MiniGUI keyboard input is realized.According to the different keypad layout demand, change the network interface keyboard mapping code to satisfy the different keyboard command control occasions.At the same time, the network interface can also be extended to LANs and WANs for remote control.
