How To Use

    M_GPS_init(huart1);
    M_GPS_bufInit(huart1);

void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) {
 if (huart->Instance == USART1) {
  M_GPS_bufCplt();
  M_GPS_bufInit(huart1);
 }
}

Getting Data

datas can be obtained directly from M_GPS structure (for more information read data structure section) or "get function"

// get locations
double M_GPS_getLatitude(void);
double M_GPS_getLongitude(void);
double M_GPS_getHeight(void);
double M_GPS_getGeoHeight(void);

// get more information
uint16_t M_GPS_getSpeed(void);
uint8_t M_GPS_getNumberOfSatellites(void);

// get time
void M_GPS_getTimeString(char *str);
uint8_t M_GPS_getHour(void);
uint8_t M_GPS_getMinute(void);
uint8_t M_GPS_getSecond(void);
uint8_t M_GPS_getMilliSecond(void);

// get date
void M_GPS_getDateString(char *str);
uint8_t M_GPS_getDay(void);
uint8_t M_GPS_getMon(void);
uint8_t M_GPS_getYear(void);

Data Structure

M_GPS

lat (latitude)

lon (longitude)

hei (height)

hgo (height of geoid)

NoS (number of satellites)

spd (speed)

time

hur (hour)

min (minute)

sec (second)

msc (millisecond)

date

yar (year)

mon (month)

day (day)

struct __M_GPS_Time{
 uint8_t hur; // hour
 uint8_t min; // minute
 uint8_t sec; // second
 uint8_t msc; // millisecond
};

struct __M_GPS_Date{
 uint8_t yar; // year
 uint8_t mon; // month
 uint8_t day; // day
};

struct {
 double lat;  // latitude
 double lon;  // longitude

 double hei;  // height
 double hgo;  // height of geoid

 uint8_t NoS; // number of satellites
 uint16_t spd; // speed

 struct __M_GPS_Time time;
 struct __M_GPS_Date date;
} M_GPS;
