Picture of My Second Project: Arduino 2.4

Last time I had a project on 16x2 LCD display. After that I thought, 'it would be awesome if using a color display instead.' When I searched a color display for Arduino UNO, I found there is limitation using UNO:

"Due to the size of the library I do not recommend using it on ATmega328 (Arduino 2009/Uno) and ATmega32U4 (Arduino Leonardo) as they only have 32KB of flash memory."

The details can be found with this link: http://henningkarlsen.com/electronics/library.php?id=51

To make this project less complicated, I also bought Arduino Mega 2560 finally. : P

This is a 2.4" TFT display with 240x320 resolution that supports both SD card and touch screen. I am so excited and wanna try it as soon as possible.

For me the requirement in hennigkarlsen.com is quite difficult to understand..... Sorry for my stupidity...... : ( Let's find another schematic that is easy to read and here is the link: http://forum.arduino.cc/index.php?topic=101029.0

A minor mistake is found and here is the amended one. I've also changed the abbreviations to match them with my TFT:

1. Display:

LEDA -> 5V

VCC -> 5V

RD -> 3.3V

GND -> GND

DB0->DB7 to pin D37->D30

DB8->DB15 to pin D22->D29

RS -> D38

WR -> D39

CS(pin15) -> D40

RSET-> D41

2. Touch Screen:

Default pin number in example code:

T_CLK->D6

T_CS(pin30) ->D5

T_DIN ->D4

T_DO->D3

T_IRQ ->D2

3. SD Card:

SD_CLK -> D52

SD_DO -> D50

SD_DIN-> D51

SD_CS -> D53

Thank you for this great tutorial! I have the same TFT, and have been searching for a way to connect it to a Ramps 1.4, to work as a screen for my 3D printer.

Can you tell me if it is possible to use the SD card part of the shield? I've read somewhere that it isn't working, and it seems to me that the IC that would control it is not there, so I think it won't work without that IC.

Keep up the good work! ;)

Very cool! Thanks for including the video!
