| Abstract: | Adapting to the rapidly developed and highly automated need of national bus operation system,this paper presents the steps and methods of using a 32bit RISC processor XScale PXA255B and a GPS-24 module to implement an intelligent station reporter based on embedded Windows CE.net.It introduces the features of the real time embedded operating system Windows CE.net,the kernel configuration and the porting process to the embedded processor XScale in detail.According to the hardware,it presents the methods of communication between the GPS module and the CPU via serial port.With the software,it adopts multi-thread programming way and divides the system task into three sub-threads,which are receiving and analyzing,LCD display and station report.It is known as multi-task. |
