printText needs 5 arguments, so that is one of the problems.

And it wants an array of integers for the first argument, not an array of characters.

3

Thanks but I'm unsure how to fix it. Can you please help me?

Thanks

First step would be to change this

void printText(int *text, uint16_t color, int x, int y,int textSize)

to

void printText(char *text, uint16_t color, int x, int y,int textSize)

Next check every call of that function.
E.g.

printText(GREEN,8,5,1);

You're not passing a text to be printed.

5 
  tft.println(GREEN,8,5,1); [code]

like this?
6

fnb111:

  tft.println(GREEN,8,5,1); [code]

like this?

Is there a text to be printed now?

7 
 tft.print (GREEN,8,5,1) [code]

I'm not sure if its a trick question.

[/code]

Again, where is the text you should add to that print (using printText, not println) ?

9 
 hours.toCharArray(timeChar,100);     //print in WHITE
    tft.print(timeChar,WHITE,20,25,3);
    dateString.toCharArray(dateChar,50);    //print in GREEN
    tft.print(GREEN,8,5,1);

[code]

I gave you an example what to look for. It's not inside the printText function, it's where you use (call) the printText function.

PS
Just throwing code around does not make it easier for us to figure out what you don't understand.

11

I don't know how to fix it or what to look for so talking in riddles is not helping me at all. Thanks anyway for the help

12

You've just posted a piece of code with two different tft.print commands. The first one has 5 parameters and no errors but the second one only has 4 parameters. You need both of them to have the required 5 parameters.

You can't just leave a parameter out and hope that the compiler will guess what you mean.

In reply #3 I gave you an example of what was wrong. Search for that line in your code and fix it. Next look for similar lines and fix them.

I apologise if I wasn't clear enough; hope its now.

14

Thanks.
I left out the dateChar. Is it possible to change the code so it uses the pc time?

15

You already have an rtc; what do you want to do with the PC time?

Anyway, you need an application on the PC that can send the time to the board, e.g. using serial. And depending on the needs, that data can e.g. be used to set the time of the RTC.
