Method 1: Install Driver 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 the TF card to PC, use SDFormatter to format the 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 --all" 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
#7inch DSI LCD (C) 1024×600 driver:
sudo bash ./WS_xinchDSI_MAIN.sh 70C 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 ".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.

dtoverlay=WS_xinchDSI_Screen,SCREEN_type=2,I2C_bus=10
dtoverlay=WS_xinchDSI_Touch,I2C_bus=10

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

Buster System Notices

1. Update the system and run the following commands:

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

Note: After updating the system, some diver files installed before may be covered, and you need to install the driver again so that it can display normally.
2. Replace the main board.
If the driver installed was for the Raspberry Pi 4 Model B and the user decides to change the mainboard, for example, change to the Raspberry Pi 3 Model B+, it may result in the display screen not showing properly.
This is because the Pi 4 and Pi 3 require loading different driver files. To ensure proper display functionality on the new mainboard, the user needs to reinstall the drivers according to the instructions #For Buster System.

Backlight Control

WaveShare provides the corresponding demo for the application (only supports Bookworm and Bullseye systems). Users can install it by the following commands:

wget https://files.waveshare.com/upload/f/f4/Brightness.zip
unzip Brightness.zip
cd Brightness
sudo chmod +x install.sh
./install.sh

After installation, you can open it: Menu -》Accessories -》Brightness:

In addition, you can also input the following commands to control the backlight brightness in the terminal:

echo X | sudo tee /sys/class/backlight/*/brightness

X indicates any number from 0 to 255. 0 means the backlight is the darkest, and 255 means the backlight is the brightest. 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 Touchscreen Rotation

• 1. Open "Screen Configuration" application.
  

• 2. Enter "Screen" -> "DSI-1" -> "Touchscreen", and select "10-0014 Goodix Capacitive TouchScreen".
  

• 3. Click "Apply", and then close the current window. Reboot according to the pop-up prompts to complete the specified touchscreen.

• 4. Enter "Screen" -> "DSI-1"->"Orientation", and select the rotation direction. Then click on "Apply" to complete the display and touch synchronous rotation.
  

Note: Only the Bookworm system supports the above synchronous rotation method, for Bullseye and Butser systems, after the display rotates, you need to set the touch rotation additionally.

Bullseye/Buster Display Rotation

• 1. Open "Screen Configuration" application:
  

• 2. Enter "Screen"->"DSI-1"->"Orientation", select the rotation direction, and then click on "Apply" to complete the display rotation.

Bullseye/Buster Touch Rotation

sudo nano /boot/config.txt
#Modify the command for the touch rotation angle at the end of the config.txt file to take effect after reboot (the command for 0° touch direction exists by default)
#90°：
dtoverlay=WS_xinchDSI_Touch,invertedx,swappedxy,I2C_bus=10
#180°：
dtoverlay=WS_xinchDSI_Touch,invertedx,invertedy,I2C_bus=10
#270°：
dtoverlay=WS_xinchDSI_Touch,invertedy,swappedxy,I2C_bus=10
#0°：
dtoverlay=WS_xinchDSI_Touch,I2C_bus=10

lite Version Rotation

sudo nano /boot/cmdline.txt
#Add the command to display the rotation angle at the beginning of the cmdline.txt file, save and reboot to take effect
#Display rotates 90°
video=DSI-1:1024x600M@60,rotate=90
#Display rotates 180°
video=DSI-1:1024x600M@60,rotate=180
#Display rotates 270°
video=DSI-1:1024x600M@60,rotate=270

Sleep Mode

Run the following commands on the Raspberry Pi, and the screen can enter the sleep mode:

xset dpms force off

Disable Touching

At the end of the config.txt file, add the following commands corresponding to disabling touch (the config file is located in the root directory of the TF card, and can also be accessed through the command: sudo nano /boot/config.txt):

disable_touchscreen=1

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