Screensaver [SOLVED]

[Simone Sandonati]

hello

you must forgive me but I do not know much about programming

I wanted to ask you can make a kind of screensaver?

when for a certain period of time is not touched, the display turns off

[Fernando Garcia]

Hi!

I didn't know anything about programming when started this project in January of 2012.

Do you'll never learn without try first.

I'll not write any custom function that need of a menu.

All this informations are important for me so, I want see it every time.

I think this function useless because the TFT never is really OFF.

Feel free to change anything on your code.

Best regards.

[Simone Sandonati]

thanks

but I do not know which way to me

I wanted to turn down the brightness to 0 when it is not used all here

thanks anyway

[Simone Sandonati]

someone can give me a help I would make sure that after 10 seconds of not using the touch is a black screen

thanks

[Fernando Garcia]

Hi!

I have an example for you.

Code: Select all

#include <UTFT.h>
#include <UTouch.h>
#include <DS1307henning.h>

extern uint8_t BigFont[];
extern uint8_t SevenSegNumFontPlus[];

unsigned long previousMillis_1 = 0;
unsigned long previousMillis_2 = 0;
int interval = 20; // In seconds

UTFT myGLCD(ITDB32WD,38,39,40,41);

// UTouch      myTouch(6,5,4,3,2); // For DIY controller
UTouch      myTouch(7,6,5,4,3);    // For Ferduino Mega 2560

//       (SDA,SCL)
//DS1307 rtc(20, 21); // For DIY controller
DS1307 rtc(18, 19); // For Ferduino Mega 2560

Time t_temp, t;

void setup()
{
  myGLCD.InitLCD();
  myGLCD.clrScr();

  myTouch.InitTouch();
  myTouch.setPrecision(PREC_MEDIUM);

  rtc.halt(false);

  mainScreen();
  previousMillis_1 = millis();
}

void loop()
{
  if(myTouch.dataAvailable())
  {
    myGLCD.clrScr();
    myGLCD.setFont(BigFont);
    myGLCD.setColor(255, 0, 0);
    myGLCD.print("Touch received!", CENTER, 110);
    delay(1000);
    previousMillis_2 = millis();
  }

  if((millis() - previousMillis_1) > 5000)
  {
    if((millis() - previousMillis_2) > interval * 1000)
    {
      clockScreen();
    }
    else
    {
      mainScreen();
    }
    previousMillis_1 = millis();
  }
}

void mainScreen()
{
  myGLCD.clrScr();
  myGLCD.setColor(255, 255, 255);
  myGLCD.setFont(BigFont);
  myGLCD.print("Waiting for touch...", CENTER, 110);
  myGLCD.setColor(0, 255, 0);
  myGLCD.print("0 degrees", 0, 0, 0);
  myGLCD.print("90 degrees", 399, 0, 90);
  myGLCD.print("180 degrees", 399, 239, 180);
  myGLCD.print("270 degrees", 0, 239, 270);
}

void clockScreen()
{
  myGLCD.clrScr();
  myGLCD.setFont(SevenSegNumFontPlus);
  myGLCD.setColor(0, 174, 255);
  myGLCD.print(rtc.getTimeStr(FORMAT_LONG), CENTER, 100);
}


Best regards.

[Simone Sandonati]

thanks

but I can not understand how to do the command that makes the black screen

[Simone Sandonati]

I am trying to use your example code ferduino

which function should I use to insert in the LOOP to make sure that if you do not touch the screen I have to display the time

because in this instance I am

Code: Select all



if((millis() - previousMillis_1) > 5000)
  {
    if((millis() - previousMillis_2) > interval * 1000)
    {
      clockScreen();
    }
    else
    {
      mainScreen();
    }
    previousMillis_1 = millis();



but does not work well because after I display the time but I also see to click the main menu


thanks


thanks

Hi!

Look for this:

https://github.com/FernandoGarcia/Ferdu ... op.ino#L97

https://github.com/FernandoGarcia/Ferdu ... p.ino#L114

Best regards.

[Simone Sandonati]

thank you very nice

they had seen the codes that I have linked, but I can not understand are not very experienced

I might have some more information?

thank you kindly

[Simone Sandonati]

thanks

Could you give me some help? I can not figure out which ones you posted

thanks

[Fernando Garcia]

Hi!

I hate give the fish.

I prefer teach get the fish.

But I think that's missing some willingness to learn.

Anyway here's your code:

In the tab "Ferduino" find:

Code: Select all

extern uint8_t BigFont[];


Add after:

Code: Select all

extern uint8_t SevenSegNumFontPlus[];


Find:

Code: Select all

int dispScreen = 0;


Add after:

Code: Select all

unsigned long previousMillis_2 = 0;
int interval = 20; // In seconds


In the tab "botoes e etc" add:

Code: Select all

void clockScreen()
{
  myGLCD.clrScr();
  myGLCD.setFont(SevenSegNumFontPlus);
  myGLCD.setColor(0, 174, 255);
  myGLCD.print(rtc.getTimeStr(FORMAT_LONG), CENTER, 100);
}


On loop find:

Code: Select all

processMyTouch();


Replace with:

Code: Select all

    if(((millis() - previousMillis_2) > interval * 1000) && (dispScreen == 0))
    {
      clearScreen();
      mainScreen(true);   
    }
    else
    {
      processMyTouch();
    }
    previousMillis_2 = millis();


Find:

Code: Select all

mainScreen();


Replace with:

Code: Select all

      if((millis() - previousMillis_2) > interval * 1000)
      {
        clockScreen();
      }
      else
      {
        mainScreen();
      }


Best regards.

[Simone Sandonati]

thanks

but it does not work also spent a lot of time does not change the time of day display

[Fernando Garcia]

Are you sure?

Watch on youtube.com

[Simone Sandonati]

I do not work. I made the changes you told me is on the home screen and never changes

these are my codes

https://drive.google.com/file/d/0B1EU3g ... sp=sharing

[Fernando Garcia]

It's ok?

Where I told for you remove "{}"?

[Simone Sandonati]

ok thanks I get

[Fernando Garcia]

[Simone Sandonati]

many thanks

because if I put more time as 30 seconti does not work?

Code: Select all


int interval = 35; // In seconds

Simone, non può essere
quel valore può essere un intero qualsiasi, quindi non può cambiare se metti 20 o 35.
Cerca il problema da qualche altra parte!
[/ITA]

It can't be... search for the problem somewhere else!

[ITA]
devi aggiugnere una { ( parentesi graffa aperta ) dopo
if(myTouch.dataAvaiable())

e dopo
if ( dispScreen ==0 )

e una } (parentesi graffa chiusa ) dopo
previousMillis_2= millis();


e dopo
mainScreen();
}

grazie

ma il problema che non mi andava l'ho risolto in effetti avevo sbagliato a non mettere le parentesi

ma la mia domanda del tempo di ritardo dei 30 secondi vi volevo chiedere che se aumento non va più in salvaschermo
