摘要
嵌入式操作系统ARM-Linux的应用已经越来越广泛,由于嵌入式设备的种类繁多,决定了在不同的嵌入式产品在开发时都必须设计和开发自己的设备驱动程序,使得嵌入式Linux设备驱动程序的开发在整个嵌入式系统开发周期中占据很大的比例。本文针对三星的S3C2410X嵌入式ARM微处理器,介绍了在Linux操作系统下,对S3C2410X微处理器内部A/D转换器的驱动方法;通过编写该A/D转换驱动程序,总结出一种在嵌入式Linux操作系统下快速方便的开发驱动程序的方法。
Embedded operating system such as the applications of ARM-Linux have become more and more popular. Because all kinds of embedded devices are different each other, we should design and develop its own device driver in the developing of the different embedded products.This makes embedded Linux device driver development occupy a heavy proportion in the whole cycle of embedded systems development. In this paper, the interface method of internal A/D converter was presented based on the Samsung S3C2410X embedded ARM microprocessor. In the preparation of A/D converter driver programming, the hardware-driven approach in Linux operating system was introduced, and a rapid and convenient development driver approach in embedded Linux operating system was also summed up in this paper.
