Hardware connection

Working with Raspberry Pi 5

1. Use the DSI-Cable-12cm cable to connect the DSI port of the display to the 22PIN DSI1 port of the Raspberry Pi motherboard.
2. Secure the Raspberry Pi to the display with M2.5 screws, ensuring that the spring pins make good contact with the Raspberry Pi.

The installation effect is as follows:

Note: Ensure that the DSI cable is connected in the correct direction and supplies 5V power to the display via the spring pins.

Working with Raspberry Pi4B/3B+/3B/3A+

1. Use a double-headed 15PIN FPC cable to connect the DSI interface of the display to the DSI interface of the Raspberry Pi motherboard.
2. Secure the Raspberry Pi to the display with M2.5 screws, ensuring that the spring pins make good contact.

The installation effect is as follows:

Note: Ensure that the DSI cable is connected in the correct direction and supplies 5V power to the display via the spring pins.

Working with CM4/CM3

1. Use the DSI-Cable-12cm cable to connect the DSI port of the display to the 22PIN DSI1 port of the Raspberry Pi motherboard.
2. Using the 4PIN PH2.0 cable, connect the 5V and GND of the display to the 5V and GND pins of the Raspberry Pi respectively.
(I2C0 touch communication is used by default, if you switch to I2C1 touch communication, you need to connect SDA1 and SCL1 pins additionally)

The installation effect is as follows:

Note: Ensure that the DSI cable is connected in the correct direction and supplies 5V power to the display via the cable.

Software settings

For Bookworm system

Method 1: Use Raspberry Pi Imager to burn the latest official image

  • 1. Insert the TF card into your PC, download and use Raspberry Pi Imager to burn the system image.

  • 2. After the burning is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of the file, 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.

dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel,8_8_inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-waveshare-panel,8_8_inch,dsi0
  • 3. 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.

Method 2: Use the pre-installed image

1. Download the Waveshare pre-installed image, and unzip it as .img file.

Image download: Waveshare 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 burning.
4. After the burning is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of the file, 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.

#DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel,8_8_inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-waveshare-panel,8_8_inch,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.


Software dimming

Waveshare 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:

43H-800480-IPS-CT-details-13.gif

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

Bookworm touch screen rotation

  • 1. Open the Screen Configuration application;

Note: Only the Bookworm system supports the above synchronization rotation method. For the Bullseye and Butser systems, manual separate settings for touch rotation are required after displaying the rotation.

lite version display rotation

sudo nano /boot/cmdline.txt
#Add a command to display the rotation angle at the beginning of the cmdline.txt file, and save it to take effect after restarting
#Display rotation 90 degrees
video=DSI-1:480x1920M@60,rotate=90
#Display rotation 180 degrees
video=DSI-1:480x1920M@60,rotate=180
#Display rotation 270 degrees
video=DSI-1:480x1920M@60,rotate=270

Screen sleep

Run the following command on the Raspberry Pi terminal and the screen will go to sleep: 

xset dpms force off

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 by the command: sudo nano /boot/config.txt): 

disable_touchscreen=1

Note: After adding a command, it needs to be restarted to take effect.
