Software Settings
Method 1: Use Raspberry Pi Imager to Flash Latest Official Image
For Raspberry Pi OS/Ubuntu/Kali/Volumio and Retropie systems.
- 1. Connect the TF card to the PC, download and use Raspberry Pi Imager to flash the corresponding system image.
- 2. After the image flashing is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of the config.txt, save and safely eject the TF card.
dtoverlay=vc4-kms-v3d #DSI1 Use dtoverlay=vc4-kms-dsi-7inch #DSI0 Use (Only Pi5/CM4) #dtoverlay=vc4-kms-dsi-7inch,dsi0
- 3. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds normally to enter the display. After the system starts, it can be touched normally.
- Note: For the Bookworm system on the Raspberry Pi 5, it is recommended to manually update to the latest system version and reboot (network connection is required).
#Update the system sudo apt-get update sudo apt-get full-upgrade -y #Reboot the system sudo reboot
Method 2: Use the Pre-installed Image
1. Select the corresponding Raspberry Pi version image, download and unzip it as .img file.
Raspberry 3/4B/CM4/5 version download: Waveshare DSI LCD - Pi3/4B/CM4/5 pre-installed image
2. Connect the TF card to the PC, format the TF card with SDFormatter.
3. Open Win32DiskImager, select the prepared system image, and click "Write" to start flashing.
4. After the flashing is completed, open the config.txt file in the root directory of the TF card, find the line "[all]", according to your display model, uncomment the relevant lines to enable the DSI display, and then save and safely eject the TF card.
Note: For Pi5/CM4/CM3+/CM3, since there are two MIPI DSI display interfaces, please make sure to use the correct display interface and instructions, the DSI1 display interface is recommended by default.
Let's take the 800*480 DSI LCD display as an example:
Use DSI1 interface:
#800*480 resolution DSI LCD display dtoverlay=vc4-kms-dsi-7inch
Use DSI0 interface:
#800*480 resolution DSI LCD display dtoverlay=vc4-kms-dsi-7inch,dsi0
5. Insert the TF card into the Raspberry Pi, power on and start, wait for a few seconds to enter the system display, and the touch function can also work normally.
Adjust Backlight Brightness
Graphical Interface Backlight Adjustment
The following steps are based on the Trixie system:
- 1. Click the menu in the upper left corner, then go to "Preferences" → "Control Center", and select "Screens";
- 2. Go to "Screen" -> "DSI-2" -> "Brightness", select and adjust the desired backlight brightness, and finally click "Apply" to save the settings.
You can also use the graphical backlight adjustment tool provided by Waveshare:
wget https://files.waveshare.com/wiki/common/Brightness.zip unzip Brightness.zip cd Brightness sudo chmod +x install.sh ./install.sh
After the installation is completed, you can open the demo in the Start Menu -> Accessories -> Brightness, as shown below:
Adjust Backlight Brightness Using Terminal
echo X | sudo tee /sys/class/backlight/*/brightness
Where X represents any number from 0 to 255. 0 means the darkest backlight, and 255 means the brightest backlight. For example:
echo 100 | sudo tee /sys/class/backlight/*/brightness echo 0 | sudo tee /sys/class/backlight/*/brightness echo 255 | sudo tee /sys/class/backlight/*/brightness
Display Rotation
Trixie / Bookworm Display Rotation
GUI interface rotation
The following steps are based on the Trixie system:
- 1. Click the menu in the upper left corner, then go to Preferences -> Control Center, and select Screens;
- 2. Go to Screen -> DSI-1 -> Touchscreen and check "10-0014 Goodix Capacitive TouchScreen";
- 3. Go to Screen -> DSI-2 -> Orientation, check the direction you need to rotate, and finally click "Apply" to complete the display and touch synchronous rotation.
- In the Bookworm system, this setting entry is located at Screen Configuration -> Screen.
lite version display rotation
- 1. Need to modify the /boot/cmdline.txt file:
sudo nano /boot/cmdline.txt
- 2. At the beginning of the cmdline.txt file, add the command for displaying the rotation angle: (Please note, this command needs to be on the same line, with each command separated by a space.)
video=DSI-1:800x480M@60,rotate=90
Change the display rotation angle by modifying the rotate value to 90, 180, or 270.
- 3. Save and restart
sudo reboot
Bullseye/Buster Display Rotation
GUI interface rotation
- 1. Open the "Screen Configuration" application;
- 2. Go to "Screen" -> "DSI-1" -> "Orientation", check the direction you need to rotate, and finally click "Apply" to complete the display rotation.
lite version display rotation
- 1. Need to modify the /boot/cmdline.txt file:
sudo nano /boot/cmdline.txt
- 2. At the beginning of the cmdline.txt file, add the command for displaying the rotation angle: (Please note, this command needs to be on the same line, with each command separated by a space.)
video=DSI-1:800x480M@60,rotate=90
Change the display rotation angle by modifying the rotate value to 90, 180, or 270.
- 3. Save and restart
sudo reboot
Stretch/Jessie Display Rotation
For some older systems, they do not use the vc4-kms-v3d or vc4-fkms-v3d driver modes, and the display rotation method is as follows:
- 1. Add a statement to the config.txt file (the config file is located in the root directory of the TF card, i.e., in the /boot folder):
display_rotate=1 #1: 90; 2: 180; 3: 270
- 2. Save the changes and then reboot the Raspberry Pi
sudo reboot
Touch Rotation
Bookworm Touch
If you use the graphical interface for rotation, you can tick "Touchscreen" in the screen layout editor window to synchronize the touch rotation. Please refer to the previous introduction for how to rotate the screen. For the command line rotation method, please refer to the following text:
1. Create a new file named 99-waveshare-touch.rules
sudo nano /etc/udev/rules.d/99-waveshare-touch.rules
2. Add the following lines as needed:
#90°:
ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 -1 1 1 0 0"
#180°:
#ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1"
#270°:
#ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1"
3. Save and reboot
sudo reboot
Bullseye/Buster Touch
After some systems display rotation, the touch direction is inconsistent, and you need to perform the following operations to perform touch rotation:
1. Install libinput
sudo apt-get install xserver-xorg-input-libinput
- If you have Ubuntu or Jetson Nano installed. The installation code is:
sudo apt install xserver-xorg-input-synaptics
2. Create the xorg.conf.d directory under /etc/X11 (if the directory already exists, proceed directly to step 3).
sudo mkdir /etc/X11/xorg.conf.d
3. Copy the 40-libinput-conf file to the directory you created just now.
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
4. Edit this file
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
#Find the touchscreen section, add the corresponding rotation angle command in it, and save it #"90° Right touch rotation: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1" #180° Inverted touch rotation: #Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1" #270° Left touch rotation: #Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1" Similar to the position in the following image:
5. Reboot Raspberry Pi
sudo reboot
After completing the above steps, touch will cause a rotation.
Screen Sleep
Run the following command on the Raspberry Pi terminal and the screen will enter sleep mode:
xset dpms force off
Note: The above command is only for Bullseye and Buster systems.
Disable Touch
At the end of the config.txt file, add the following command corresponding to disabling touch (the config file is located in the root directory of the TF card, which can also be accessed via the command: sudo nano /boot/config.txt):
disable_touchscreen=1
Note: After adding a command, it needs to be restarted to take effect.

The hardware connection between DSI LCD and Pi5:
(1) A DSI cable (official Raspberry Pi cable or Waveshare Pi5-Display-Cable-200mm) for Pi 5 is required. Please ensure the proper orientation with the SODIMM.
(2) Priority usage for Pi5's DSI1 interface.
If use the DSI0 interface, you need to add "dtoverlay=vc4-kms-dsi-7inch,dsi0" in the config.txt file
2. Check the DSI LCD version.
(1) The latest DSI LCD version compatible with Pi5 is Rev2.2, which can be directly used.
(2) If you purchased the product earlier, such as the Rev2.1 version (or older), due to the power detection mechanism of Pi5, it may misidentify the capacitors on the DSI LCD as a false short-circuit state, preventing the system from booting. In this situation, you can manually remove the large capacitors at the four positions marked in red circles in the image below.
3.Software Setup:
For the Pi5, use the Bookworm system. (Please note, Pi5 currently only supports Bookworm, not Bullseye or Buster).
(1) Go to the Raspberry Pi official website: https://www.raspberrypi.com/software/operating-systems/. Download the latest version of the Bookworm image. Download the compressed file to your PC and extract it to obtain the .img file.
(2) Connect the microSD card (TF card) to your PC and use the SDFormatter software to format the microSD card.
(3) Open the Win32DiskImager software. Select the system image prepared in Step 1 and click 'Write' to flash the system image.
(4) After the writing process is complete, open the 'config.txt' file in the root directory of the microSD card. Add the following code at the end of 'config.txt', save it, and safely eject the microSD card.
dtoverlay=vc4-kms-v3d dtoverlay=vc4-kms-dsi-7inch
(5) Insert the TF card into the Raspberry Pi, power it, and then enter after waiting for a few seconds. Then, the system boots and can be touched mormally.
Note that if use the DSI0 interface at the same time, you need to add the additional commands: "dtoverlay=vc4-kms-dsi-7inch,dsi0"
