20.5. Longitude function interface
The Yoctopuce class YLongitude allows you to read the longitude from Yoctopuce geolocalization
sensors. It inherits from the YSensor class the core functions to read measurements, register callback
functions, access the autonomous datalogger.
In order to use the functions described here, you should include:
js
<script type='text/javascript' src='yocto_longitude.js'></script>
nodejs
var yoctolib = require('yoctolib');
var YLongitude = yoctolib.YLongitude;
cpp
#include "yocto_longitude.h"
m
#import "yocto_longitude.h"
pas
uses yocto_longitude;
vb
yocto_longitude.vb
cs
yocto_longitude.cs
java
import com.yoctopuce.YoctoAPI.YLongitude;
uwp
import com.yoctopuce.YoctoAPI.YLongitude;
py
from yocto_longitude import *
php
require_once('yocto_longitude.php');
es
in HTML: <script src="../../lib/yocto_longitude.js"></script>
in node.js: require('yoctolib-es2017/yocto_longitude.js');
