Software Settings

For Bookworm and Bullseye System

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

• 1. Open the "Screen Configuration" application;
  

• 2. Go to "Screen" -> "DSI-2" -> "Brightness", check the backlight brightness you need to set, and finally click "Apply" to complete the backlight setting.

Waveshare also provides a corresponding demo (the demo is only used for Bookworm and Bullseye systems), users can download, install and use in the following way:

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:

In addition, you can also control the brightness of the backlight by entering the following command on the 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

Bookworm Display Rotation

GUI interface rotation

• 1. Open the "Screen Configuration" application;
  

• 2. Go to "Screen" - > "DSI-1" - > "Touchscreen" and check "6-0038 generic ft5x06(79)"
  

• 3. Click "Apply" and close the current window. Restart according to the pop-up prompt, and then touch screen select Done.

• 4.Go to "Screen" -> "DSI-1" -> "Orientation", check the direction you need to rotate, and finally click "Apply" to complete the display and touch synchronous rotation.

-->
Note: Only the Bookworm system supports the above synchronization rotation method. Note: Only the Bookworm system supports the above synchronous rotation methods. For Bullseye and Butser systems, after displaying rotation, touch rotation needs to be manually set separately.

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:

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.
