本计划之目的在于开发一开放源码之具有GUI 接口之嵌入式网路 行 动通讯装置。将发展潜力 雄厚由Google开发之网路 通讯软件GoogleTalk 整合移植于一嵌入式开发板上，再外加一无线网卡时，此系统即成为网路 行 动通讯装置(network mobile communication device)。Googletalk 为一功能强大之通讯软件具有简讯、语音、影像、档案传送等网路 通讯功能，并具有多方通讯(conferencing)之功能，且其账号之取得与通话费用完全免费，只需注册为Gmail 之用户即可，相信在此方便 性与google 之强力 推广下，其用户數 有朝一日将可与Skype 分庭抗禮 。本计划使用Intel Xscale PXA270做为硬件开发平台，以embedded linux为操作系统核心，移植Google所释出的libjingle，配合USB无线网卡来实现无线嵌入式 GoogleTalk。
The purpose of this project is to develop an open source it has a GUI interface to the embedded network mobile communication devices. Strong development potential will be developed by the Google GoogleTalk integration of network communication software, embedded development board in a transplant, and then plus a wireless network card, this system is a network mobile communication devices (network mobile communication device). Googletalk of a powerful communications software with SMS, voice, video, file transfer and other network communication, and communication with the multi-(conferencing) function, and the account of the cost of acquisition and the call is free, just sign up for the Gmail of users can, I believe that in this convenience of the strong force with the promotion of google, its users and Skype numbers will one day be the Chamber of anti Ceremony. The plan to use the Intel Xscale PXA270 as hardware development platform for the embedded linux operating system kernel, release (2011-05-09, Unix_Linux, 7532KB, 下载7次)
