摘要：本文著重闡述了基于嵌入式系統(tǒng)PDA在Windows CE平臺(tái)下實(shí)現(xiàn)紅外通訊功能的開(kāi)發(fā)方法，目的在于實(shí)現(xiàn)遵從IrDA標(biāo)準(zhǔn)的PDA系統(tǒng)與和IrDA標(biāo)準(zhǔn)不兼容的紅外設(shè)備進(jìn)行通訊。主要內(nèi)容涉及PDA針對(duì)與IrDA協(xié)議不兼容設(shè)備進(jìn)行紅外通訊的解決辦法，相關(guān)驅(qū)動(dòng)程序設(shè)計(jì)方法與開(kāi)發(fā)策略，以及實(shí)際驗(yàn)證與研究結(jié)論等，核心的技術(shù)思路是通過(guò)對(duì)紅外通訊協(xié)議進(jìn)行自定義進(jìn)而繞開(kāi)IrDA協(xié)議，通過(guò)EVC開(kāi)發(fā)環(huán)境開(kāi)發(fā)相關(guān)驅(qū)動(dòng)程序?qū)DA進(jìn)行下載，從而通過(guò)PDA的URAT串行端口發(fā)送與協(xié)議相對(duì)應(yīng)的編碼到IR收發(fā)器，實(shí)現(xiàn)需求的紅外通信功能。文中對(duì)技術(shù)方法、設(shè)計(jì)思路、開(kāi)發(fā)流程、編譯環(huán)境，以及驅(qū)動(dòng)程序主要模塊的關(guān)鍵源代碼，給予了充分的闡述和說(shuō)明；展示了程序在EVC環(huán)境中的運(yùn)行界面，并通過(guò)下載驅(qū)動(dòng)程序到實(shí)際PDA上實(shí)際驗(yàn)證，成功實(shí)現(xiàn)了基于自定義紅外協(xié)議對(duì)不兼容IrDA標(biāo)準(zhǔn)的紅外設(shè)備進(jìn)行控制。

The Realizing of PDA Communication by User-defined Infrared Protocol Base on WinCE
Abstract: Method of realizing an infrared communication of PDA base on Windows CE platform is introduced to demonstrate the communication between IrDA-protocol-compatible PDA with non-IrDA-protocol-compatible device. The proposed solution, the driver design and development pattern, testing and conclusion are covered. The key idea is to define a user defined infrared communication protocol rather than following IrDA protocol. The driver is built by EVC compiler and downloaded to PDA so that the infrared signal compatible with user-defined protocol can be sent to IR transceiver through the UART of PDA to realize the infrared communication function.
