摘要
针对ARM平台设计LVDT位移传感器的接入电路,并在LINUX操作系统下编写传感器电路的驱动程序;提出一种在嵌入式QT界面中对模/数转换后的数据的读取方法。最终程序可以很好地运行在开发板上,验证了软、硬件的有效性和可靠性。该功能已经成功应用于某嵌入式智能测量仪器中。
We design LVDT displacement sensor access circuit for ARM platform, prepare the sensor circuit driver to the Linux operating system and descript a data acquisition method which experienced the conversion of analog / digital in QT embedded interface. Finally the procedure can be used to run on the development board, which certificate the validity and reliability of software and hardware. The function has been successfully applied to an embedded intelligent measurement instruments.
