About this project

In this tutorial I will show you how to print an image on an analogue TV. For that we will need an "TVout" library, but it is only able to print black and white shapes.

1. You need to have the image you are going to print on your TV2. You must reduce it to a size of 128x64 or smaller3. Go to http://marlinfw.org/tools/u8glib/converter.html and there uploud the picture4. Copy the code

CODE

CODE .h:

#include <avr/pgmspace.h>

#ifndef CAR_H

#define CAR_H

extern const unsigned char car[];

#endif

CODE

#include "car.h"

PROGMEM const unsigned char car[] = {

30, 10, //pictureresolution

0x03,0xFF,0xC0,0x00, //copied code

0x0F,0x04,0x30,0x00,

0x7F,0xC6,0x1C,0x00,

0x7F,0xFF,0xFF,0xF0,

0xFF,0xFF,0xFF,0xF8,

0xFF,0xFF,0xFF,0xFC,

0xFD,0xFF,0xFE,0x7C,

0xFC,0xFF,0xFE,0x3C,

0x1C,0xFF,0xFE,0x70,

0x07,0x80,0x03,0xC0

};

CODE: .ino

#include <TVout.h>

#include "car.h"

TVout TV;

void setup() {

TV.begin(_PAL, 128, 96); //PAL or NTSC

}

void loop() {

TV.clear_screen();

TV.bitmap(10, 10, car);

delay(60);}

CONNECT

Now upload your code☺

Code

CAR.inoArduino
#include <TVout.h>
#include "car.h"


TVout TV;

void setup() {
  // put your setup code here, to run once:
TV.begin(_PAL, 128, 96);

}

void loop() {
  // put your main code here, to run repeatedly:
TV.clear_screen();
TV.bitmap(10, 10, car);
delay(60);
}
