[[ITDB02-2.2S]] module is 2.2" SPI TFT LCD with 262K color 320 x 240 resolutions. The controller chip of this LCD module is ILI9341, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Since its interface is SPI, you need 6 Dupont lines (SCK,MISO,MOSI,CS,D/C,RST) to control this LCD module. Moreover, this module integrates an SD card slot.

  • LEDA: When LEDA is set as high electronic level, the backlight turns on. When it's set as low electronic level, the backlight turns off.

Instruction

Display the image from micro SD card

  • 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
  • Power UNO main board, a picture of dog showed on the display.

Control LEDA backlight via PWM pins

  • Use arduino IDE to open the demo 0.1Basics\Fade, then upload it into UNO
  • Connect ITDB02-2.2S module to UNO according to the table as below:
2.2S pins UNO pins
VCC 5V
GND GND
LEDA D9
  • Power UNO main board, you will see the backlight of display turn form dark to light circularly.
