嵌入式linux終端驅(qū)動(dòng)及通信程序開發(fā)

1、華北電力友學(xué)碩士學(xué)位論文摘要自從1991年首次公開發(fā)表以來，Linux的應(yīng)用范圍就越來越廣泛。嵌入式linux是將普通linux操作系統(tǒng)進(jìn)行裁剪、修改，使之能在嵌入式計(jì)算機(jī)上運(yùn)行。由于具有hnux和嵌入式系統(tǒng)的優(yōu)點(diǎn)，嵌入式linux系統(tǒng)有著巨大的市場(chǎng)一前景。本論文的研究就在于研究風(fēng)力發(fā)電機(jī)組的工業(yè)控制器的一些問題，在基于開源的Linux系統(tǒng)和嵌入式芯片at91rm92OO的目標(biāo)板上，完成串口終端的驅(qū)動(dòng)，分析驅(qū)動(dòng)的調(diào)試重點(diǎn)和難點(diǎn)，以及驅(qū)動(dòng)

2、程序的移植問題。實(shí)現(xiàn)工業(yè)現(xiàn)場(chǎng)使用廣泛的modbus協(xié)議，實(shí)現(xiàn)分散控制等工業(yè)應(yīng)用所需的數(shù)據(jù)和指令傳輸功能。完成基于TCP工P的數(shù)據(jù)傳輸軟件的開發(fā)。關(guān)鍵詞:ARM，Linux，終端驅(qū)動(dòng)，調(diào)試，移植ABSTRACTSince1991distributionforthefirsttime，theaPPlicationofLinux15moreandmorewidely.EmbeddedLinux15anoPerationsystemwhieh1
