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.能显示micro SD中的图片
- 第一:下载并安装Adafruit_ILI9340的库:https://github.com/adafruit/Adafruit_ILI9340
- 第二,把Adafruit_ILI9340\examples\spitftbitmap目录下的woof.bmp图片拷贝到micro SD卡中。然后把SD卡插到ITDB02-2.4S模块的micro SD卡座上。
- 第三,用UNO烧写程序。用arduino IDE打开Adafruit_ILI9340中spitftbitmap的例子。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 |
- 插上电源,屏幕上会显示一只狗的图片。
