基于ARM的GPS/GPRS多功能手持终端的设计与实现

摘要

The structure of GPS Multi -function Handheld Terminal based on ARM9 MCU and embedded Linux is developed. The GPS/GPRS Multi-function Handheld Terminal uses S3C2410 as the Core controller, GR-87 Serials as GPS module, MC39i as GPRS module, and 3. 5 inches TFT LCD as the output device, the resistance type touch screen as the input device which are easy to use. The GPS/ GPRS Multi-function Handheld Terminal can also be used in vehicle. Except position fixing and navigation, GPS/GPRS Multi - function Handheld Terminal also supports several new digital functions like sound recording, multi -angles photograph, mass storage and so on.%基于ARM微处理器和嵌入式Linux操作系统的GPS/GPRS多功能手持终端采用ARM9系列处理器S3C2410作为主控单元的核心控制器,台湾HOLUX公司的GR-87 Serials作为GPS模块,西门子公司的MC39i作为GPRS模块,3.5寸的TFT LCD作输出设备,电阻式触摸屏作输入设备；该多功能手持终端还可用于车辆导航,同时还具有录音、影音播放、大容量存储等功能；该终端通过软硬件测试,可长时间稳定工作.
