I am looking for internet time M5Stack for Arduino ide

felmue

are you sure? From the description Rob developed ezTime together with M5ez for M5Stack.

What exactly doesn't work for you? Care to share your code?

Thanks
Felix

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

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?!🤔

Stoni99

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

macsbug

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（）;" 👍
