Hello Marco. Thanks for your reply.

I want to display time, date and year (RtcDS3231.h) with scroll effect (MD_Parola.h, MAX72xx.h) on a 32×8 MAX7219 matrix with a NodeMCU8266.

Everything is displayed correctly in the serial monitor of the Arduino IDE.

But time, date and year are not displayed on the Max7219 matrix ;-(

What am I doing wrong (line 128 to 144)????

I would be very happy if you could take a look at the skecht and help me with these lines.

Here the code:

The code P.print(( currentTime.Hour) && ( currentTime.Minute)); Is not corrrect. In C++ && operator is a boolean operator. You are using this operator correctly in your if statements at the end of the loop() function.

MD_Parola requires you to pass through a c-string for it to display and the c-string must remain in scope for the duration of the animation. You are creating a c-string in str above these lines to display debug on the serial monitor - you should initially try and display this c-string to the matrix to confirm that your code is correct.

In order to display with scrolling you cannot use .print(). You will need to restructure the code to allow the animation to take place (no delay() and a free running loop() function). The Parola_Zone_TimeMsg example is close to what you need to do - just ignore the zone related stuff and focus on how the loop() code is structured to display different messages in sequence.

Hello Marco.

Thanks for the tips!

I have now changed the example (Parola_Zone_Mesg) and use DS1307 with your library. I have reduced the sketch to the display of the time. But the time of the RTC is not displayed. Only 00:00 is displayed according to "Font_Data.h".

Now I don't know what to do.

Best regards

The Code

// Program to demonstrate the MD_Parola library
//
// Display the time in one zone and other information scrolling through in
// another zone.
// - Time is shown in a user defined fixed width font
// - Scrolling text uses the default font
// - Temperature display uses user defined characters
// - Optional use of DS1307 module for time and DHT11 sensor for temp and humidity
// - DS1307 library (MD_DS1307) found at https://github.com/MajicDesigns/DS1307
// - DHT11 library (DHT11_lib) found at http://arduino.cc/playground/Main/DHT11Lib

You have not eliminated the code that references zones completely. The below should display the time, updated each second. If you are still getting 00:00 then you may have comms issues to the clock module. ` void loop(void) { ... P.displayAnimate();

// Finally, adjust the time string if we have to
if (millis() - lastTime >= 1000)
{
    lastTime = millis();
    getTime(szTime, flasher);
    flasher = !flasher;

    P.displayReset();
}

... } `

Hello Marco.

Thank you very much for your renewed help!!!

Now the time is displayed correctly, but when a full hour is reached and the MP3 file is called up, the clock stops at the hour.

I have no idea how to solve this.

I would be very happy if you could help me ONE LAST TIME ;-)

Best regards

Paul

Does the clock restart when the tune stops playing? Does the tune play at all?

It seems to me that your logic should be that the minutes and the seconds should be == 0 to play the tune otherwise the tune play request will be sent the whole time that minutes == 0 (which is check many times per second).

Comment out the code block (all the if statements) that play your tunes. Does the clock still stop? If the clock does not stop then the calls to mtDFPlayer.play() are the problem.

I would move the check to play the tune only when the clock is updated because the second has passed. There is no need to check at other times. I would also point out that you can simplify your code a lot if you make sure that tune number N is played at hour number N (or N+1, or some other direct relationship):

  if (millis() - lastTime >= 1000)
  {
    lastTime += 1000;
    getTime(szTime, flasher);
    flasher = !flasher;
    P.displayReset();
    if (RTC.h == 6 && RTC.m == 35 && RTC.s == 0)  // 6:35:00 Uhr Wecken
        myDFPlayer.play(25);
    else if (RTC.m == 0 && RTC.s == 0)
        myDFPlayer.play(RTC.h+1);
   }

Hello Marco.

Würdest Du mir dabei auch unter die Arme greifen?

Thanks for your help and patience ;-)

So far it has been running smoothly.

But now I am looking for a solution,

the time information == 19, == 5, == 0 in line 174 (alarm time) as variables via Bluetooth Serial send, without every time upload a new alarm time via IDE.

Would you also help me with this?

Best regards

Paul

Good to know that things are now working more smoothly.

I think this additional functionality is beyond just helping you with the functions of the MD_Parola library. There are many examples on the internet for doing this Bluetooth comms and there is also MD_Parola examples that use Bluetooth to set the display message, so you can look at that. Also, there is the Arduino forum that has many people willing to help for this kind of general problem.

[FAK142]

Can i use this library for P10 LED Display Panel Module - 32x16 ?

[MajicDesigns]

Please do not hijack threads for unrelated issues, especially when the original issue is already closed. In future please open a new enquiry.

I don't know what a P10 matrix is. The library will only work with LEDs controlled by the MAX7219 or MAX 7221 IC.
