摘要
嵌入式系统的驱动程序是应用程序与嵌入式系统硬件之间的一个中间接口层,操作系统只有通过这个接口,才能控制硬件设备工作。在嵌入式系统开发过程中,音频设备的驱动程序移植问题非常多,为了系统化地解决移植过程中遇到的各类问题,针对已经建立的S3C2410硬件平台,在嵌入式Linux平台上移植UDA1341声卡驱动,分析了UDA1341芯片的技术特点和音频驱动程序主要模块的设计思路,总结了驱动程序在嵌入式系统平台上的移植方法和步骤,分析并解决了移植通用UDA1341驱动程序过程中遇到的各类问题,并且通过了具体测试(实现了音频设备的所有功能,如录音、音量控制等),取得了较好效果。
Embedded system driver is the interface layer between application and hardware of the embedded system.Operating system only controls the hardware devices through this interface.In the development process of the embedded system,there is so much problem about driver transplantation of audio equipment.In order to solve the migration problems systematically,in accordance with the hardware platform of S3C2410,the UDA1341 sound card driver is transplanted on the embedded Linux platform,the characteristics and the audio driver design idea of the main modules on the UDA1341 chip technology are analyzed.The methods and procedures of the driver transplantation in the embedded system platform are summed up.Different kinds problem of transplanting the common UDA1341 drive are analyzed and solved,the specific test and is passed good results（implement all the features of the audio device,such as recording,volume control,etc.） are achieved.
