DSI-22PIN Interface Definition



Hardware Connection

Working with Pi 4B/3B+/3A+/3B/2B/B+/A+

1. Connect the 7inch DSI LCD to the 15PIN DSI1 interface on the Raspberry Pi board using the DSI-Cable-12cm cable.
2. Connect the LCD power interface to the 5V and GND pins on the Raspberry Pi board using the 2PIN power cable.
3. For convenient use, the Raspberry Pi 4 can be mounted onto the back of the 7inch DSI LCD using screws, with the brass standoffs installed as shown below:

Working with Pi 5/CM4/CM3+/CM3

1. Connect the 7inch DSI LCD to the 22PIN DSI1 interface on the Raspberry Pi board using the DSI-Cable-12cm cable.
2. Connect the LCD power interface to the 40PIN GPIO header on the Raspberry Pi using the 2PIN power cable.
3. For convenient use, the Raspberry Pi 5 can be mounted onto the back of the 7inch DSI LCD using screws, with the brass standoffs installed as shown below:


Software Configuration

Method 1: Flash the Latest Official Image Using Raspberry Pi Imager

Compatible with Raspberry Pi OS, Ubuntu, Kali, Volumio, and RetroPie systems for Raspberry Pi.

  • 1. Connect the TF card to your PC, download and use Raspberry Pi Imager to flash the corresponding system image.

  • 2. After flashing the image, open the config.txt file in the root directory of the SD card. Add the following code at the end of config.txt, save the file, and safely eject the SD card.
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-ili9881-7inch
  • 3. Insert the SD card into the Raspberry Pi and power it on. The display should start working normally after approximately 30 seconds. Touch functionality will also work normally once the system has booted (Default username: pi; password: raspberry).

Adjusting Backlight Brightness

  • 1. Click the menu in the upper-left corner, navigate to Preferences → Control Center, and select Screens.

  • 2. Navigate to "Screen"->"DSI-1"->"Brightness", select the desired backlight brightness, and click "Apply" to complete the brightness configuration.

You can also use the graphical backlight adjustment tool provided by us. (This program is only compatible with Bookworm and Bullseye systems.) Enter the following commands in the terminal to download, install, and use the tool:

wget https://www.QD.net/w/upload/f/f4/Brightness.zip
unzip Brightness.zip
cd Brightness
sudo chmod +x install.sh
./install.sh

After installation, you can launch the program from Start Menu -> Accessories -> Brightness, as shown below:

Display Rotation

Display Rotation on Bookworm

Rotate via GUI

  • 1. Open the "Screen Configuration" application.

  • 2. Navigate to "Screen"->"DSI-1"->"Touchscreen" and select "10-005d Goodix Capacitive TouchScreen".

  • 3. Click "Apply" and close the current window. Follow the prompt to restart the system. The touchscreen selection process will then be complete.

  • 4. Navigate to "Screen"->"DSI-1"->"Orientation", select the desired rotation direction, and click "Apply" to synchronize the rotation of the display and touchscreen.

Note: The above synchronized rotation method is only supported on Bookworm. For Bullseye and Butser systems, touchscreen rotation must be configured separately after rotating the display.

Touch Mode Selection

Trixie and Bookworm systems support two touch modes, which can be switched in the Screen Configuration > Touchscreen menu:

  • 1. Mouse Emulation (Default)
Single tap = Left mouse button function
Long press = Right mouse button function
Double-click supported
Page scrolling and multi-touch gestures are not supported

Note: This mode is suitable for scenarios requiring mouse-like operations, such as double-clicking to open File Manager and long-pressing to trigger the right-click function.

  • 2. Multitouch
Supports multi-touch functionality
Supports page scrolling
Double-click and right-click via long press are not supported

Note: This mode is suitable for touch-optimized applications, such as web browsing and scrolling through lists.
