  • Adjustable brightness via software.

Working with Raspberry Pi

Hardware Connection

Use a 15PIN FPC cable to connect the 2.8inch DSI LCD to the DSI interface of the Raspberry Pi.

Software Setting

Method 1: Install Manually

  1. Download the image of the newest version Raspberry Pi, download the compressed file to the PC, and extract the .img file.
  2. Connect TF card to PC, use SDFormatter to format TF card.
  3. Open Win32DiskImager software, select the system image prepared in step 1 and click write to burn the system image.
  4. After the programming 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 an HDMI display or log in remotely with SSH).
#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 in the terminal to view the kernel version and cd to the corresponding file directory
#6.1.21 then run the following command
cd 6.1.21
#Step 3: Please check the bits of your system, enter the 32 directory for 32-bit systems, and enter the 64 directory for 64-bit systems
cd 32
#cd 64
#Step 4: Enter your corresponding model command to install the driver, pay attention to the selection of the I2C DIP switch
#2.8inch DSI LCD 480×640 Driver:
sudo bash ./WS_xinchDSI_MAIN.sh 28 I2C0
#Step 5: Wait for a few seconds, when the driver installation is complete and no error is prompted, restart and load the DSI driver and it can be used normally
sudo reboot

Note: The above steps need to ensure that the Raspberry Pi can be connected to the Internet normally.
5. Wait for the system to restart, it will be able to display and touch normally.

Method 2: Program Pre-install Image

1. Select your corresponding Raspberry Pi version image, download and decompress it as a ".img" file.
Raspberry Pi 4B/CM4 version download: Waveshare DSI LCD - Pi4 pre-install image
Raspberry Pi 3B/3B+/CM3 version download: Waveshare DSI LCD - Pi3 pre-install image
2. Connect the TF card to the PC and use SDFormatter to format the TF card.
3. Open Win32DiskImager software, choose the system image prepared in the first step, and then click "write" to write the system image.
4. After the programming is finished, open the config.txt file in the root directory of the TF card, add the following code under [all], save, and eject the TF card safely.


5. Connect the TF card to the Raspberry Pi, and start the Raspberry Pi, wait for about 30 seconds to display and touch normally.


Method 1: Graphical Interface Rotation

In the start menu, select: Preferences -> Screen Configuration -> Configure -> Screens -> DSI-1 -> Orientation, select the corresponding angle in it, click "√", select Yes, and restart.

Method 2: Rotation Display In Lite Version

sudo nano /boot/cmdline.txt
#Add a command to display the rotation angle at the beginning of the cmdline.txt file, save and reboot to take effect
#Display rotates 90 degrees
#Display rotates 180 degrees
#Display rotates 270 degrees

Touch To Rotate

sudo nano /boot/config.txt
#Modify the instruction of the touch rotation angle at the end of the config.txt file, and it will take effect after restarting (there is a 0° touch direction instruction by default)

Backlight Control

Method 1: Graphical Interface Dimming

Using the application provided by Waveshare:

cd Waveshare-DSI-LCD
# Determine the currently used kernel version, such as the 5.15.61 kernel, and run the following command
cd 5.15.61
#Check the bits of the system, the 32-bit system enters 32 directory, and the 64-bit system enters 64 directory
cd 32
#cd 64
cd Backlight
sudo ./install.sh

After the installation is complete, you can open the program in the Start menu - > Accessories - > Brightness, as shown below:

Method 2: Lite Version Dimming Command

To adjust the system command of the lite version, after entering the root privilege, execute the following command on the Raspberry Pi terminal:

echo X > /sys/waveshare/rpi_backlight/brightness

(X value in the range of 0~255.)
For example:

sudo su root
echo 100 > /sys/waveshare/rpi_backlight/brightness


1. Update the system, such as executing the following command:

sudo apt-get update
sudo apt-get full-upgrade

After updating the system, some files of the originally installed driver may be overwritten, and the driver needs to be reinstalled to display normally.
2. Replace the motherboard:
If the driver is originally installed on the Raspberry Pi 4 Model B, the user replaces the motherboard, such as modifying it to a Raspberry Pi 3 Model B+, and the display will not display properly.
Because Pi4 and Pi3 need to load different driver files, you need to reinstall the driver on the new motherboard to display properly.
