CODE SNIPPET
This snippet shows the procedure for parsing a string received by the GPS module. Library for GPS implements RX buffer which stores characters coming from the GPS device. The parser will detect when a complete sentence has been provided and parse it into its respective elements. This library is usable on various types of GPS devices.
1 void parse_gps( int *lat, int *lon )
2 {
3 char *string = strstr(txt,"$GPGLL");
4 if( string != 0 ) {
5 if( string[7] != ',' ) {
6 *lat = ( string[7] - 48 )*10 + ( string[8] - 48 );
7 *lon = ( string[19] - 48 )*100 + ( string[20] - 48 )*10 + ( string[21] - 48 );

10 *lat = 0 - latitude;
11 if(string[31] == 'W')
12 *lon = 0 - longitude;
