ITDB02-2.4S

Overview

ITDB02-2.4S module is 2.4" SPI TFT LCD with 262K color 320 x 240 resolutions. The controller chip of this LCD module is ILI9341V. Since its interface is SPI, you need 6 Dupont lines (SCK,MISO,MOSI,CS,D/C,RST) to control the LCD module. Moreover, there is an on-board micro SD card slot for multimedia storage and data logging purposes. This 2.4" LCD is a resistive touchscreen as well, so you can detect finger presses anywhere on the screen.

Features

• Compatible for 3.3/5V operating level
• Integrated with an micro SD card slot
• Support IO/PMW to control the backlight
• Resistive touchscreen

Instruction

1.Touch Function

• Upload 2_4_spi_touch.ino into UNO main board
• Connect ITDB02-2.4S module to UNO according to the table as below:

2.2S pins	UNO pins
VCC	5V
GND	GND
SCK	D13
MISO	D12
MOSI	D11
CS	D10
D/C	D9
RST	D8
LEDA	5V/3V3
SD_CS	D4
T_CS	D2
T_IRQ	D3

• Power UNO mainboard, you can start to draw any line or pattern on the screen.

2.Display the image from micro SD card

• Download the library from this link: https://github.com/adafruit/Adafruit_ILI9340 , then extract it into the directory \arduino\libraries
• Copy the image woof.bmp from the directory Adafruit_ILI9340\examples\spitftbitmap to your SD card, then plug the card into the SD card slot on ITDB02-2.2S LCD module
• Use arduino IDE to open spitftbitmap.ino in the directory Adafruit_ILI9340\examples\spitftbitmap then upload it to UNO main board.
• Select 5V electronic level in the 2.2S LCD module, then use dupont lines to connect UNO and LCD module according to the table as below:

2.2S pins	UNO pins
VCC	5V
GND	GND
SCK	D13
MISO	D12
MOSI	D11
CS	D10
D/C	D9
RST	D8
LEDA	5V/3V3
SD_CS	D4
