Software Configuration

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

For Raspberry Pi OS / Ubuntu / Kali / Volumio and RetroPie systems.

• 1. Connect the TF card to a PC, download and launch [https\://www\.raspberrypi.com/software Raspberry Pi Imager], and 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 become active after approximately 30 seconds. Touch functionality will work normally after the system starts. (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 backlight 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 and install it:

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, open the program from Start Menu -> Accessories -> Brightness, as shown below:

Display Rotation

\Display Rotation on Bookworm\

\GUI Rotation

• 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 will then be completed.

• 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 synchronized rotation method described above is supported only on Bookworm. On Bullseye and Butser systems, touchscreen rotation must be configured separately and manually 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
Supports double-click
Does not support page scrolling or multi-touch functionality\

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

• 2. Multitouch

Supports multi-touch functionality
Supports page scrolling
Does not support double-click or long-press right-click functionality\

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