1.gps模块的选择,看到论坛里有兄弟买了模块接不上,晕,有没有usb接口的gps模块?
The difficult part is in UART configuration for UART interface GPS module.
2.如果有usb接口的模块,那么在linux平台下,是否支持?
If it can be supported on a Linux PC, so it will be on mini2440. Google may be a good help once you've found one.
3.LCD显示问题,用qt实现还是minigui?
It depends on your GPS application implementation, QT-based or minigui-based.
