嵌入式Linux下PC/104数据采集模块驱动实现

Implementation of PC/104 Data Acquisition Module Driver Under Embedded Linux

为扩展PC/104嵌入式系统的应用环境,开发了Linux环境下PC/104数据采集模块DIAMOND-MM-32-AT的驱动程序。首先,分析了数据采集模块DIAMOND-MM-32-AT的工作模式。然后,在自构建嵌入式Linux系统环境下,按照Linux驱动程序规范,实现了PC/104数据采集模块的驱动程序。最后,开发了远程数据采集系统,包括服务器端程序和客户端程序。通过实验表明:所设计的数据采集驱动程序是正确的,而且具有高可靠性。

To extend application of the PC/104 embedded system,this paper designed and realized the drive of the PC/104 data acquisition module DIAMOND-MM-32-AT under the embedded Linux environment.The paper analyzed the working pattern of the DIAMOND-MM-32-AT data acquisition module.Then,under the self building embedded Linux environment,it realized the drive of the PC/104 data acquisition module according to the Linux driver specifications.Finally,it developed the remote data acquisition system including the server and client.The result of experience shows that the drive is correct and high reliability.
