Can the Labeled Value widget Display Leading Zeros from RTC time data?

Need Help With My Project
1

Hi, Im using the RTC widget to display the time on Labeled Value widgets on my project. The widgets work well, time is displayed correctly, however . . . when any of H, M or S are single digits, only the single digit is displayed:

eg 8:48:8 or 21:3:56

Is it possible to display the leading zero in the Labeled Display widget for the single digits?

eg. 08:48:08 or 21:03:56

I’ve found answers for formatiing for Serial Print (RTC code to show value on widget), and I’ve tried expanding similar formatting that works for floats in the Labeled Value widget (eg /pin.##/) - I tried /pin.##.##.##/ but this didnt work.

Suggestions greatly appreciated.

Your answer was right there in the link you provided… works just fine for a labled display

This is what I use:

char currentTime[9];
char currentDate[11];

void timedateDisplay() {
sprintf(currentTime, "%02d:%02d:%02d", hour(), minute(), second());
sprintf(currentDate, "%02d/%02d/%04d", month(), day(), year());
Blynk.virtualWrite(V0, currentTime);  // Send time to Display Widget
Blynk.virtualWrite(V1, currentDate);  // Send date to Display Widget
}

Of course you still need any RTC stuff :wink:

Great, thnx for the quick response! I’m not familiar with sprintf(), with the brief reding I’ve done I ASSUMED (first mistake . . .) that it was formatting for serial print only. Will try this out as soon as I get home later today,

Well, probably not it’s official name, but I call it serialprintformat() :stuck_out_tongue_winking_eye: and once the data is formatted, it can be used for a serial print or equivalent, in our case a display widget :wink:

Maybe it was as stringprintformat…

That makes more sense :+1:
