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
