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:
7inch-DSI-LCD-E-details-7.jpg

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 CM5/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 Setting

For Trixie and Bookworm System

  • 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.
Note: Since Pi5/CM5/CM4/CM3+/CM3 has two mipi DSI interfaces, please note that the correct DSI interfaces and commands are used, DSI1 is recommended by default.
dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel,8_0_inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-waveshare-panel,8_0_inch,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, the touch function can be used normally.

For Bullseye and Buster System

Method 1: Install Driver Manually

1. Download the latest version of the image from the Raspberry Pi official website, download the compressed file to your PC, and extract it as .img file.
2. Connect the TF card to the PC, format the TF card with SDFormatter software.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click Write to flash the system image.
4. After the flashing is completed, connect the TF card to the Raspberry Pi, start the Raspberry Pi, and log in to the terminal of the Raspberry Pi (you can connect the Raspberry Pi to the HDMI display or use ssh to log in remotely).

#Step 1: Download and enter the Waveshare-DSI-LCD driver folder
git clone https://github.com/waveshare/Waveshare-DSI-LCD
cd Waveshare-DSI-LCD
#Step 2: Enter uname -a on the terminal to view the kernel version, and cd it to the corresponding file directory #6.1.21 then run the following command cd 6.1.21
#Step 3: Please determine the bits of the current system you are using. For a 32-bit system, proceed to the 32 directory, and for a 64-bit system, proceed to the 64 directory cd 32 #cd 64
#Step 4: Enter your corresponding model command to install the driver, pay attention to the selection of the I2C dip switches #10.1inch DSI LCD(C) 1280×800 Driver: sudo bash ./WS_xinchDSI_MAIN.sh 80C I2C0
#Step 5: Wait for a few seconds, when the driver installation is complete and no error is displayed, restart and load the DSI driver to use it normally sudo reboot #Note: The steps above require that the Raspberry Pi can connect to the Internet normally

5. Wait for the system to restart, and it will be able to display and touch normally.

Method 2: Flash Pre-installed Image

1. Select your corresponding Raspberry Pi version image, download and unzip it as .img file.
Raspberry Pi 4B/CM4 version download: Waveshare DSI LCD - Pi4 pre-installed image
Raspberry 3B/3B+/CM3 Version Download: Waveshare DSI LCD - Pi3 pre-installed image
2. Connect the TF card to the PC, format the TF card with SDFormatter software.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click Write to flash the system image.
4. After the flashing is completed, open the config.txt file in the root directory of the TF card, add the following code under [all], save and safely eject the TF card.

dtoverlay=WS_xinchDSI_Screen,SCREEN_type=8,I2C_bus=10
dtoverlay=WS_xinchDSI_Touch,invertedx,swappedxy,I2C_bus=10

5. Connect the TF card to the Raspberry Pi, start the Raspberry Pi, and wait for about 30 seconds before it can be displayed and the touch function can be used 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";

In the Bookworm system, this setting entry is located at "Screen Configuration" → "Screen".

Use Waveshare Backlight Adjustment Application

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

Trixie/Bookworm Display Rotation

GUI interface rotation
The following steps are based on the Trixie system:

  • In the Bookworm system, this setting entry is located at "Screen Configuration" -> "Screen".
Note: The above synchronous rotation method is only supported on Trixie/Bookworm system systems. For the Bullseye/Buster system, the touch rotation needs to be set manually and individually after the rotation is displayed.


Bullseye/Buster Display Rotation

  • 1. Open the "Screen Configuration" application;

Bullseye/Buster Touch Rotation

sudo nano /boot/config.txt
# The command to modify the touch rotation angle at the end of the config.txt file will take effect after restarting (the command for 0° touch direction exists by default)
#0°:
dtoverlay=WS_xinchDSI_Touch,invertedx,swappedxy
#90°:
dtoverlay=WS_xinchDSI_Touch,invertedx,invertedy
#180°:
dtoverlay=WS_xinchDSI_Touch,invertedy,swappedxy
#270°:
dtoverlay=WS_xinchDSI_Touch

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-1:1280x800M@60,rotate=90
#Display rotation 180 degrees
video=DSI-1:1280x800M@60,rotate=180
#Display rotation 270 degrees
video=DSI-1:1280x800M@60,rotate=270

Set Screen Off and On

Run the following command on the Raspberry Pi terminal and the screen will be turned off:

wlr-randr --output DSI-2 --off
# DSI-2 needs to be modified to the actual display in use, e.g. "DSI-1" or "HDMI-A-1"

Run the following command on the Raspberry Pi terminal and the screen will be turned on:

wlr-randr --output DSI-2 --on
# DSI-2 needs to be modified to the actual display in use, e.g. "DSI-1" or "HDMI-A-1"

Note: This command is only applicable to the Labwc and Wayfire graphical interfaces and not to the X11 graphical interface.

Screen Sleep

Run the following command on the Raspberry Pi terminal and the screen will enter sleep mode:

xset dpms force off

Note: This command is only applicable to the X11 graphical interface and not to the Labwc and Wayfire graphical interfaces.

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.
