摘要

提出了以嵌入式微处理器S3C2440为核心,在嵌入式ARM-Linux2.6.12操作系统上实现红外通信与解码驱动的设计方案.介绍了红外遥控系统结构和红外遥控系统中专用发射芯片(TC9012)编码方式,在此基础上结合嵌入式Linux和驱动程序设计框架,详细阐述了嵌入式Linux2.6.12系统上红外遥控解码的驱动程序开发并讨论了驱动程序的编译加载方法.通过Linux图形用户界面下的应用程序测试其红外解码驱动,实践并验证了该设计在ARM平台上通信稳定,具备优良的正确性、准确性和实时性.%The design of infrared communication and decode driver in embedded ARM-Linux2.6.12 based on the S3C2440 microprocessor is proposed. It introduces system structure of infrared remote control and remote control ASIC (TC9012) coding methods. In addition combining with embedded Linux and framework of drivr programming, the development of device drivers for infrared remote control decoding and compiling method of drivers in embedded Linux2.6.12 operating system is detailed. Finally application testing under the Linux system GUI verifies that the driver program for communication is stability and reliably on ARM platform as well as excellent correctness, accuracy and real-time performance.
