TI DSP 28335 平台；gps.c主是NMEA0183协议，将字符串转化为经纬度等数据，存入结构体；convertGeoToUTM.c将经纬度换算为UTM坐标；Example_2833x.c是主函数，不能直接运行，项目中其它代码都删掉了，仅保留了串口中断服务函数。(The TI DSP 28335 platform; gps.c is the main NMEA0183 protocol, string into latitude and longitude data structure into convertGeoToUTM.c; the coordinates to UTM coordinates conversion; Example_2833x.c is the main function, can not directly run, other project code are deleted, leaving only the interrupt service function.)
