NTPClient Archieven - DomoticX Knowledge Center

Installatie van Arduino IDE libraries: Arduino info Met deze bibliotheek kan je de tijd (en datum) ophalen van een NTP server. Voorbeeld:

#include <NTPClient.h>
// change next line to use with another board/shield
#include <ESP8266WiFi.h>
//#include <WiFi.h> // for WiFi shield
//#include <WiFi101.h> // for WiFi 101 shield or MKR1000
#include <WiFiUdp.h>

const char *ssid     = "<SSID>";
const char *password = "<PASSWORD>";

WiFiUDP ntpUDP;

// By default 'time.nist.gov' is used with 60 seconds update interval and
// no offset
NTPClient timeClient(ntpUDP);

// You can specify the time server pool and the offset, (in seconds)
// additionaly you can specify the update interval (in milliseconds).
// NTPClient timeClient(ntpUDP, "europe.pool.ntp.org", 3600, 60000);

void setup(){
  Serial.begin(115200);
  WiFi.begin(ssid, password);

  while ( WiFi.status() != WL_CONNECTED ) {
    delay ( 500 );
    Serial.print ( "." );
  }

  timeClient.begin();
}

void loop() {
  timeClient.update();

  Serial.println(timeClient.getFormattedTime());

  delay(1000);
}

#include <NTPClient.h>

Changelog:

3.1.0 patched
- Added feature for date

3.1.0
- Added functions for changing the timeOffset and updateInterval later. Thanks @SirUli

3.0.0
- Constructors now require UDP instance argument, to add support for non-ESP8266 boards
- Added optional begin API to override default local port
- Added end API to close UDP socket
- Changed return type of update and forceUpdate APIs to bool, and return success or failure
- Change return type of getDay, getHours, getMinutes, and getSeconds to int

2.0.0
- Add missing empty constructor for the Basic example
- Remove the need for calling begin() and make sure to always try to force update if there was no update yet.

1.0.0
-Initial Release
