基于PXA250的嵌入式系统中红外通信实例

An Example of Infrared Communication in the Embedded System Based on PXA250

随着性能的飞速发展,嵌入式设备已经成为人们身边不可或缺的重要组成部分。红外通信是一种无线通信方式,其高性能和连接简便等特征非常适合移动设备的应用。基于PXA250嵌入式处理器的开发平台介绍一个红外通信的实例。首先介绍了硬件信息及系统的连接,随后重点讨论了系统初始化的一般流程以及红外通信代码的编写。整个设计流程不仅针对红外通信,而且对于基于相似架构处理器的外设应用都有一定的借鉴意义。

With remarkable increasing in performance, embedded pr od ucts have become an indispensable part of everyday items. Infrared communication is a mode of wireless communication that now plays an important role in embedde d systems. Infrared communication, with its high level performance and easy conn ection, especially suits the use of portable devices. This paper will provide an example of infrared communication in the embedded system based on PXA250. In th e paper, an introduction to hardware environment is first presented. Then follow s a discussion specific to the common procedure of hardware initialization and a pplication code. The design flow will be helpful to other applications with simi lar architecture.
