Instruction
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 |
- 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.
