Additionally it was tested with a shield where the SARA-G350 RX/TX/PWRON is connected to D0/D1/D4 and the GPS SCL/SDA is connected D15/D15. In this configuration the following platforms were tested (it is likely that others will work as well) - U-BLOX: C027-XX. - NXP: LPC1549v2 - Freescale: FRDM-KL25Z, FRDM-KL46Z - STM: NUCLEO-F401RE, NUCLEO-F030R8 */ #if defined(TARGET_UBLOX_C027) #define C027_USEONBOARD // remove this if you have the GSM/GPS shield mounted #endif #ifdef C027_USEONBOARD #include "C027.h" C027 c027; #endif // no tracing if serial is shared with the VCP #define DOTRACE ((USBRX!=MDMRXD)&&(USBTX!=MDMTXD)) #define TRACE (!DOTRACE)?:printf int main(void) { int ret; char buf[2048] = ""; // only trace if the serial is different from our modem port if (DOTRACE) { Serial pc(USBTX,USBRX); pc.baud(115200); } wait_ms(1000); TRACE("GSM/GPS Support Example\r\n"); // turn on the supplies of the Modem and the GPS c027.mdmPower(false); c027.gpsPower(true); wait(2); // Create the GPS object #if GPSADR // use GPSI2C class GPSI2C gps(GPSSDA,GPSSCL,GPSADR); #elif GPSBAUD // or GPSSerial class GPSSerial gps(GPSTXD,GPSRXD,GPSBAUD); #else #warning "please define the pins for the GPS" #endif // open the PC serial port and (use the same baudrate) Serial pc2(P4_28, P4_29); pc2.baud(9600); TRACE("Checking GPS\r\n"); // char link[128] = ""; // unsigned int i = 0xFFFFFFFF; const int wait = 100; bool abort = false; //DigitalOut led(LED1); double hdop=99.99; while (!abort) { // led = !led; while ((ret = gps.getMessage(buf, sizeof(buf))) > 0) { int len = LENGTH(ret); // TRACE("NMEA: %.*s\r\n", len-2, buf); // pc2.printf("NMEA: %.*s\r\n", len-2, buf); #if 1 if ((PROTOCOL(ret) == GPSParser::NMEA) && (len > 6)) { if (!strncmp("$GPGLL", buf, 6)) { double la = 0, lo = 0; double utc; char ch; if (gps.getNmeaAngle(1,buf,len,la) && gps.getNmeaAngle(3,buf,len,lo) && gps.getNmeaItem(5,buf,len,utc) && gps.getNmeaItem(6,buf,len,ch) && ch == 'A') { // TRACE("GPS Location: %.5f %.5f\r\n", la, lo); TRACE("%06d,%.6f,%.6f\r\n", (long)utc, la, lo); pc2.printf("%06d,%.6f,%.6f,%.2f\r\n", (long)utc, la, lo, hdop); // sprintf(link, "I am here!\n" // "https://maps.google.com/?q=%.5f,%.5f", la, lo); } } if (!strncmp("$GPGSA", buf, 6)) { gps.getNmeaItem(16,buf,len,hdop); } } #endif #if 0 if ((PROTOCOL(ret) == GPSParser::NMEA) && (len > 6) && !strncmp("$GPGGA", buf, 6)) { double la = 0, lo = 0; double utc, alt; char ch; if (gps.getNmeaAngle(2,buf,len,la) && gps.getNmeaAngle(4,buf,len,lo) && gps.getNmeaItem(11,buf,len,alt) && gps.getNmeaItem(1,buf,len,utc) && gps.getNmeaItem(6,buf,len,ch) && ch == 'A') { // TRACE("GPS Location: %.5f %.5f\r\n", la, lo); TRACE("%06d,%.6f,%.6f,%.2f\r\n", (long)utc, la, lo, alt); pc2.printf("%06d,%.6f,%.6f,%.2f\r\n", (long)utc, la, lo, alt); // sprintf(link, "I am here!\n" // "https://maps.google.com/?q=%.5f,%.5f", la, lo); } } #endif } wait_ms(wait); } gps.powerOff(); TRACE("Shutdown\r\n"); // now it is safe to switch LDOs off c027.gpsPower(false); return 0; }
