아래는 mbed Web compiler에서 사용한 Source Code이다. 위의 링크로 가면 GPS/OLED의 Library도 같이 볼수 있다.
include the mbed library with this snippet
/* Example showing how to hook up to different GPS modules (GlobalSat EM406a and Adafruit Ultimate GPSv3) * to emulated serial ports at different speeds */ #include "mbed.h" #include "GPS.h" #include "Adafruit_SSD1306.h" class I2CPreInit : public I2C { public: I2CPreInit(PinName sda, PinName scl) : I2C(sda, scl) { frequency(100000); start(); }; }; #ifdef TARGET_WIZwiki_W7500 GPS gpsAda(D1, D0, 9600); I2CPreInit gI2C(PA_10,PA_9); #else GPS gpsAda(P0_12, P0_15, 9600); GPS gpsSpark(P0_4, P0_0, 4800); #endif // an SPI sub-class that provides a constructed default Adafruit_SSD1306_I2c gOled(gI2C,NC,0x78,64,128); Serial pc(USBTX, USBRX); int main() { char ch[] = {"Adafruit"}; char ch1[] = {"Sparkfun Breakout"}; gOled.begin(); gOled.clearDisplay(); while (1) { #ifndef TARGET_WIZwiki_W7500 if(gpsSpark.sample()) { pc.printf("set %c\t%f\t%f\t%f\t%f\t%f\n\r", 'Sparkfun Breakout', gpsSpark.longitude, gpsSpark.latitude, gpsSpark.alt, gpsSpark.geoid, gpsSpark.time); } #endif if(gpsAda.sample()) { pc.printf("set %s\t%f\t%f\t%f\t%f\t%f\n\r", ch, gpsAda.longitude, gpsAda.latitude, gpsAda.alt, gpsAda.geoid, gpsAda.time); //Time gOled.printf("T : %Lf\n", gpsAda.time); //longitude(경도) gOled.printf("LO : %f\n", gpsAda.longitude); //latitude(위도) gOled.printf("LA : %f\n", gpsAda.latitude); gOled.printf("AL : %f\n", gpsAda.alt); gOled.printf("G : %f\n", gpsAda.geoid); gOled.display(); gOled.setTextCursor(0,0); } } }
결과
현재 내가 있는 위치의 GPS정보이다.
아래의 그림은 구글 지도에서의 GPS정보이다.
표로 정리하면 아래와 같다.
OLED | google map | |
latitude(위도) | 37.377090 | 37.378633 |
longitude(경도) | 127.113701 | 127.113032 |
