I have been working on a super simple sketch to prove a concept for how I can get the float values for latitude and longitude, then convert them into a char array so I can output them to a website.
#include<stdlib.h>
void setup() {
Serial.begin(115200);
float latitude = 47.2035;
float longitude = 15.3268;
char latBuffer[50];
char longBuffer[50];
char fullBuffer[100];
dtostrf(latitude, 0, 7, latBuffer);
dtostrf(longitude, 0, 7, longBuffer);
sprintf_P(fullBuffer, PSTR("Latitude: %s;Longitude: %s"), latBuffer, longBuffer);
Serial.println(fullBuffer); // Prints: "Latitude: 47.2035;Longitude: 15.3268"
}
void loop(){}
Whilst this sketch does compile if I set the board type to be Arduino Uno, when I change it to MKR GSM 1400 it fails to compile with the error:
float-to-char-array:12: error: 'dtostrf' was not declared in this scope
dtostrf(latitude, 0, 7, latBuffer);
^
exit status 1
'dtostrf' was not declared in this scope
So I am just wondering if there are plans to have the "dtostrf" added to the standard library availble to the MKR GSM 1400.
Thanks
