TvOut library problem

Projects Libraries
1

Hi, How can I view the variables using the TvOut library? When I put my program in: TV.print (variable)
The program doesn't compile

2

Hard to tell without seeing your code

Please copy and paste the entire compile error message in a new post.

BTW, Development->Libraries isn't the right sub-forum for this.

@aarg Sorry if it's in the wrong place but I'm new here. My error:

My program:

#include <TVout.h>
#include <fontALL.h>
String zmienna="test";

TVout TV;

void setup()  {
  TV.begin(_NTSC,184,72);
  TV.select_font(font6x8);
  TV.println(zmienna);
}

void loop() {

}

You can't use the String class. Try

#include <TVout.h>
#include <fontALL.h>
char *zmienna="test";

TVout TV;

void setup()  {
  TV.begin(_NTSC,184,72);
  TV.select_font(font6x8);
  TV.println(zmienna);
}

void loop() {

}

@anon57585045 The program is compiling, thank you. But I can't say it works, do you know why? The screen shows something like this:

Did you try the library example sketch?

10

Yes

11

...and?

12

the example works

13

Which TVout library are you using? I found several. Please provide a link.

I downloaded the library so long ago that I don't remember where I got it from ... :frowning:
But I can send the library file I have
