How to drive a TFT display (Arduino)
It is quite easy to drive a SPI 128*160 TFT display with a ITDB18SP controller when you use the UTFT library of Rinky-Dink.

Just wire everyhting as the picture shows above, flash the code and have fun with the demo pics.
Here you can see the example code of Rinky-Dink where you only have to change the controller and the pinout.

//
// This program is a demo of the drawBitmap()-function.
//
// This demo was made to work on the 128x128 modules.
// Any other size displays may cause strange behaviour.
//
// This program requires the UTFT library.
//
#include <UTFT.h>
#include <avr/pgmspace.h>
#define SDA 9
#define SCL 8
#define CS 12
#define RST 11
#define RS 10
UTFT myGLCD(ITDB18SP,SDA,SCL,CS,RST,RS); // Remember to change the model parameter to suit your display module!
extern unsigned int icon1[0x400];
extern unsigned int icon2[0x400];
extern unsigned int tux[0x1000];
void setup()
{
myGLCD.InitLCD(PORTRAIT);
}
void loop()
{
// Draw a 4 by 4 grid of a 32x32 icon.
myGLCD.fillScr(255, 255, 255);
for (int x=0; x<4; x++)
for (int y=0; y<4; y++)
myGLCD.drawBitmap (x*32, y*32, 32, 32, icon1);
delay(5000);
// Draw a 64x64 icon in double size.
myGLCD.fillScr(255, 255, 255);
myGLCD.drawBitmap (0, 0, 64, 64, tux, 2);
delay(5000);
// Draw a 2 by 2 grid of a 32x32 icon in double size.
myGLCD.fillScr(255, 255, 255);
for (int x=0; x<2; x++)
for (int y=0; y<2; y++)
myGLCD.drawBitmap (x*64, y*64, 32, 32, icon2, 2);
delay(5000);
}
If you want to display some photos, you will find in the download of the UTFT Library a tool where you can convert photos into .c files.
Just put the files into the directory of the .ino file and place a code line with referencing to the .c file.
Now you are able to see a funny pic on your TFT display.
