使用指南
1.触摸功能
- 把 2_4_spi_touch.ino 烧写进 UNO 主板
- 然后按照以下的接线方式连接UNO和ITDB02-2.4S模块：
| 2.4S 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 |
- 插上电源后，可以在屏幕上随意画出任何图案或线条。
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:
| 2.4S 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.
