基于S3C2440A的嵌入式电子地图的设计

Design of Embedded Electronic Map Based on S3C2440A

本文实现MapInfo格式电子地图在S3C2440A嵌入式平台上的设计与显示。首先基于S3C2440A的硬件平台,在Linux操作系统下,完成Qt/Embedded到平台的移植,使其支持图形显示;接着以MapInfo格式的桌面电子地图文件为数据来源,根据需要对数据进行裁减,并选用合适的数据结构组织数据,实现嵌入式电子地图在平台上的显示,达到预期显示效果。

In this paper, the electronic map saved as MapInfo format is designed and displayed on the embedded platform of S3C2440A. First on the hardware platform of S3C2440A, in the Linux operating system, we transplant Qt/Embedded to the platform. Then we use the desktop electronic map in MapInfo＇s format as data source, reduce the electronic map in accordance with the need, select the suitable data structure for the data organization, and display the embedded electronic map on the platform. The results achieve the expected results.
