摘要
在PC104模块硬件平台和嵌入式Linux系统下,设计并实现PC104总线结构数据采集卡DMM-16-AT的设备驱动程序。利用嵌入式Linux平台,设计设备驱动程序与系统引导、操作系统内核以及外部设备三者间的接口,屏蔽DMM-16-AT的硬件特性,通过文件系统实现对DMM-16-AT的访问操作。该方法解决了工业色谱仪在嵌入式Linux下通过DMM-16-AT进行采样的问题。
The device driver of PC104 data acquisition card is designed and implemented in the embedded Linux environment based on the PC104 platform. The interfaces between the device driver and system boot, system kernel, peripheral devices separately are also designed. By using this driver, characteristics of all hardware are masked and DMM-16-AT can be accessed easily through file system. It is proved that this driver can solve the sampling problems on industrial chromatograph by DMM-16-AT in embedded Linux environment.
