Use struct data type to declare, create and use it in a function. The struct functions are abstracted in a seperate folder to show how it can be used and referred in the main.ino
.
The struct LatLong
can be declared:
struct LatLong {
double latitude;
double longitude;
};
The struct can be defined:
LatLong latlong = {1.2480631, 103.8285657};
The struct can be used in a function declaration:
void goToSentosa(struct LatLong *);
The struct can be used in a function definition:
void goToSentosa(struct LatLong *ll) {
...
}
#include "src/latlong/latlong.h"
LatLong latlong = {1.2480631, 103.8285657};
void setup() {
Serial.begin(9600);
while (!Serial) { }
Serial.println("Locations of places around the world!");
}
void loop() {
goToSentosa(&latlong);
Serial.print("Sentosa: (");
Serial.print(latlong.latitude, 6);
Serial.print(", ");
Serial.print(latlong.longitude, 6);
Serial.println(")");
goToEiffelTower(&latlong);
Serial.print("Eiffel Tower: (");
Serial.print(latlong.latitude, 6);
Serial.print(", ");
Serial.print(latlong.longitude, 6);
Serial.println(")");
