红外通信有着成本低廉、连接方便、简单易用和结构紧凑的特点，因此在小型移动设备中获得了广泛的应用。这些设备包括笔记本电脑、掌上电脑、机顶盒、游戏机、移动电话、计算器、寻呼机、仪器仪表、MP3播放机、数码相机及打印机之类的计算机外围设备等。红外线数据虽然使用得非常普遍，但有关红外程序的编写，以及红外协议的介绍比较少。因而，使得红外线程序的编写显得有些神秘。本文将探讨Palm J2ME的红外线通信程序的设计。-Infrared communication with low-cost, easy connection, easy to use and the characteristics of compact structure, so small mobile devices access to a wide range of applications. These devices include notebook computers, handheld computers, set-top boxes, game consoles, mobile phones, calculators, pagers, instruments, MP3 players, digital cameras and printer of the type of computer peripheral equipment. Although the use of infrared data very common, but the preparation of the IR process, and introduces less IR protocol. Thus, making the preparation of infrared seemed to be somewhat mysterious process. This article will explore the Palm J2ME infrared communication program design.
