摘要
Pipeline型模数转换器AD9248采用分段、流水线式的方式,提高了数据转换速度,在高速数据采集中占据了重要地位。利用ARM9微处理器S3C2440和AD9248设计了一种双通道高速雷电数据采集系统,详细分析了在嵌入式Linux2.6.12平台下AD9248驱动程序的开发及编译过程,测试结果表明驱动运行正常且结果准确。
Pipelined AD9248 has higher conversion rate for using a three-segments structure and a pilelined architecture,so it occupies a key position among the high-speed data acquisition systems.A dual high-speed lightning data acquisition system was designed based on ARM9 microprocessor S3C2440 and AD9248.This paper detailed analyzed the Linux device driver development and compile of AD9248 based on the platform of embedded operation system Linux 2.6.12.The test result shows the driver works normally and the result is accurate.
