[SOLVED] WidgetRTC Conv to > 12Hour AM PM Time Format?

Lane0138 · March 10, 2017, 7:23pm

All,

I’ve churned through the forum for an answer to what I’m sure is a simple solutions, but I can’t find it. I’ve come close with @JoeS but can’t make it work .

Using WidgetRTC and the default code provided by @vshymanskyy how do you convert military time into a standard 12hr format with the AM, PM displayed??? Do I use hour12() inplace of hour() ? If so, how do you get the AM PM, isAM() or isPM()? Are these just True/False statements?

THANKS IN ADVANCE !

Cheers,

This is really more a Google question, solved by math (i.e you can code the difference in your sketch)

Lane0138 · March 10, 2017, 7:48pm

Ya, @Gunner, I get the math! Thanks for pointing it out. At the end of the day this whole forum could be replaced with Google searches. Just to be fair I followed your link provided. It was a useless link. If you don’t know the answer to a simple question to help out other Blinkers on a topic under the heading "Need Help With My Project", maybe you should just pass. Again… maybe someday we’ll all know everything about Blynk, C++. Until that day comes, I’d still appreciate constructive advice.

Cheers,

Gunner · March 10, 2017, 7:50pm

You are closer to the mark then you think on that one This is a Blynk forum, but many of the questions ARE NOT Blynk related… that does muddy up the waters for those who have Blynk specific issues.

Lane0138 · March 10, 2017, 7:52pm

WidgetRTC = Blynk

I’m going to stick with, it’s a valid question. I’m sorry if these inquiries are beneath some people.

Gunner · March 10, 2017, 7:56pm

Even with Blynk, it still comes down to some form of code to manipulate the data to ones own preferences.

WidgetRTC = Blynk = Data generated != not the way you want it = Google for math solution to code differently = RESULTS!!! Yay!

Insulting others in forum = being ignored or banned

Lane0138 · March 10, 2017, 7:59pm

I couldn’t agree with you more.

Jamin · March 10, 2017, 8:04pm

@Lane0138, the Time library has a documentation page which covers 12 hr convertions.

FYI, Time lib is not Blynk related and Google found this link

Lane0138 · March 10, 2017, 8:29pm

@Jamin, I’ll go back and review those pages again. I’ve looked through them at length prior to this post and didn’t understand the integration into the code.

Thanks

Jamin · March 10, 2017, 8:36pm

I’ll give you a hand since its super stormy this weekend and its totally a computer day…

void clockDisplay()
{
  sprintf(Time, "%02d:%02d:%02d", hourFormat12(), minute(), second());
  sprintf(Date, "%02d/%02d/%04d",  month(), day(), year());
  Serial.print("\tCurrent time: ");
  Serial.print(Time);
  Serial.print("\t");
  Serial.print(Date);
  Serial.println();

  if(isAM()){
    Time += String(" AM");
  } else {
    Time += String(" PM");
  }

  Blynk.virtualWrite(V1, String(Time));
  Blynk.virtualWrite(V2, Date);
}

Give that a go…

Lane0138 · March 10, 2017, 8:42pm

Thank You !!! @Jamin

I saw that in the Time Library but I couldn’t ever get the “hourFormat12()” to work. Rookie Syntax !

I hadn’t even got to the AM PM part yet.

Thank You Again… for lending me your knowledge.

Sorry about the weather !!

Lane0138 · March 10, 2017, 9:08pm

@Jamin,

I dread this post but… it won’t compile.

I’m getting:
49: error: no match for ‘operator+=’ (operand types are ‘char [20]’ and ‘String’)
Time += String(" PM");

Thanks for the Tip’s !

Gunner · March 10, 2017, 9:10pm

Good example @Jamin Thank Heavens for bad beach days (once in awhile ;))

Syntax beats my hacked math method… I think it messes up on 0:00 hours… but then I wasn’t really doing any research as I prefer the military time (keeps me thinking) and I didn’t feel like being a code monkey today

void clockDisplay()
{
  int HOUR = hour();
  if ( HOUR > 12 ) {
    HOUR = HOUR - 12;
    String currentTime = String(HOUR) + ":" + minute() + ":" + second() + " PM";
    Blynk.virtualWrite(V12, currentTime);  // Send PM time to the App
  } else {
    String currentTime = String(hour()) + ":" + minute() + ":" + second() + " AM"; ;
    Blynk.virtualWrite(V12, currentTime);  // Send AM time to the App
  }
  String currentDate = String(month()) + " " + day() + " " + year();
  Blynk.virtualWrite(V13, currentDate);  // Send date to the App
}

Lane0138 · March 10, 2017, 9:18pm

Thank you both @Gunner and @Jamin for your coding assistance.

I couldn’t get the code to work right, so I asked for help.

Not my intention to turn someone into a “Code Monkey”.

Since I’m not a Pro-Coder and don’t understand A-Z, I’m going to guess that’s not a flattering comment.

Thank you for your help non the less.

Lane0138

Jamin · March 10, 2017, 9:18pm

Just change your define for Time.

String Time; // instead of char Time

On a side note, avoid char variables… they just suck to convert lol

Gunner · March 10, 2017, 9:24pm

You are speaking to a total amateur coder here as well… and while I do appreciate examples to glean from, I still rely HEAVILY on Google and Arduino - Home and try to only ask Blynk specific questions now (except when I am begging for Linux help… then I whimper like a baby ;P)

All is well… If I didn’t really care to help, even in a “Tough Love” format (as one other put it), I would NEVER answer anyone’s postings

Lane0138 · March 10, 2017, 9:26pm

Great tip!!!

Thank You - - - Again

  int HOUR;
  char APM[4]="";


void Timedate(){

  if ( hour() > 12 ) {
    HOUR = hour() - 12;
    strcpy(APM,"PM");

    } else {
    HOUR = hour();
    strcpy(APM,"AM");
    }
    
    String currentTime = String(HOUR) + ":" + minute() +":" + second() + " " + APM + "  " + month() + "/" + day() + "/" + year();
    terminal.println(currentTime);
    terminal.flush();
  }
