I am looking for internet time M5Stack for Arduino ide



  • I tried example codes. After establishing the Internet connection, the M5Stack crashes and restarts. He doesn't seem to tolerate waitForSync();

    #include <M5Stack.h>
    #include "WiFi.h"
    #include "ezTime.h"

    const char *ssid = "xxxxxxxxxxx";
    const char *password = "xxxxxxxxxxx";

    void setup(){
    //Serial.begin(115200);
    M5.begin();
    M5.Power.begin();
    WiFi.mode(WIFI_STA);
    WiFi.disconnect();
    delay(100);
    WiFi.begin(ssid, password);
    M5.Lcd.print("Call to " + String(ssid));
    while (WiFi.status() != WL_CONNECTED) {
    M5.Lcd.print('.');
    delay(1000);
    }
    M5.Lcd.println(" ");
    M5.Lcd.println(WiFi.localIP());
    M5.Lcd.print("Signalstearke: ");
    M5.Lcd.println(WiFi.RSSI());
    //server.begin();
    delay(2000);
    M5.Lcd.clear();

    waitForSync();
    M5.Lcd.println();
    M5.Lcd.println("Time in various internet standard formats ...");
    M5.Lcd.println();
    M5.Lcd.println("ATOM: " + dateTime(ATOM));
    M5.Lcd.println("COOKIE: " + dateTime(COOKIE));
    M5.Lcd.println("IS8601: " + dateTime(ISO8601));
    M5.Lcd.println("RFC822: " + dateTime(RFC822));
    M5.Lcd.println("RFC850: " + dateTime(RFC850));
    M5.Lcd.println("RFC1036: " + dateTime(RFC1036));
    M5.Lcd.println("RFC1123: " + dateTime(RFC1123));
    M5.Lcd.println("RFC2822: " + dateTime(RFC2822));
    M5.Lcd.println("RFC3339: " + dateTime(RFC3339));
    M5.Lcd.println("RFC3339_EXT: " + dateTime(RFC3339_EXT));
    M5.Lcd.println("RSS: " + dateTime(RSS));
    M5.Lcd.println("W3C: " + dateTime(W3C));
    M5.Lcd.println();
    M5.Lcd.println(" ... and any other format, like "" + dateTime("l ~t~h~e jS ~o~f F Y, g:i A") + """);
    delay(6000);
    }

    void loop() {
    events();
    }



  • Hello @Stoni99

    your code runs fine on my M5Stack.

    • what happens if you comment out waitForSync()?
    • what is the log output of the crash?

    Thanks

    I'm using the World Time API.
    It is good to use it according to the area.

    What do you mean by comment out?
    I don't have log output , it just restarts.

    Code works - thanks!



  • Hi guys

    @macsbug : thank you for presenting the World Time API as alternative solution.

    @Stoni99 : never mind - I am glad to read you have working code now.

    Thanks
    Felix



  • ezTime.h seems easier to condition?!🤔



  • ezTime.h works now. I have updated to new Version. Thx!



  • Hello@stoni99

    ezTime.h

    I modified the following and got the result.

    Fix;
    #include <WiFi.h>
    #include <ezTime.h>
    //waitForSync();

    result;
    Time in various internet standard formats ...

  • Ahhh - ok: "//waitForSync();" 👍
