摘要
目前,仪器操作系统的要求日益增长。由于Linux已经被广泛地用于嵌入式系统,所以Linux为仪器操作系统提供了一种新的可能性。本文选择典型仪器AV1486信号发生器作为实现目标,Linux作为操作系统,Qt/Embedded作为GUI,进行了实现。主要内容包括启动部分实现、专用键盘驱动程序的开发、GUI的实现、点频信号的产生等等。最后进行了实验分析,结果表明,Linux可实现对信号发生器的有效支持。
because of development of high-performance instruments, instrumental OS is becoming more and more important. Linux offered new possibility for instrumental OS because Linux had been widely used in embedded system. The paper chose typical instrument AV1486 as goal, Linux as OS and QT/Embedded as GUI; they were realized in Signal Generator. The main content included : realization of startup section, development of special keyboard driver, realization of graphic user interface, producing of dot-frequency signal, and so on. Finally, experiment was carried out; the result demonstrated that Linux may effectively support Signal Generator.
