Hardware connection

Working with Pi 4B/3B+/3A+/3B/2B/B+/A+

1. Using the FFC cable, connect the 7inch DSI LCD to the 15PIN DSI interface of the Raspberry Pi board.
2. Use the 2PIN power cable to connect the LCD power port to the 40PIN GPIO header of the Raspberry Pi.

3. For convenience, you can fix the Raspberry Pi on the back of the 7inch DSI LCD with screws, and install standoffs.
The effect as shown below:

Working with Pi 5/CM4/CM3+/CM3

1. Connect the 7inch DSI LCD to the 22PIN DSI1 interface of the Raspberry Pi with DSI-Cable-12cm.
2. Use the 2PIN power cable to connect the LCD's power port to the 40PIN GPIO headers of the Raspberry Pi.

Software Setting

Raspberry Pi OS Imager Insallation

For Raspberry Pi OS/Ubuntu/Kali and Retropie system:

  • 1. Connect the TF card to the PC, download and use Raspberry Pi Imager to program the corresponding system.

  • 2. After installing the imager, open the "config.txt" file on the TF card root directory, add the following codes at the end of "config.txt", and then safely remove the TF card.
Note: as there are two MIPI DSI interfaces on the Pi5/CM4/CM3+/CM3, please pay attention to using the correct DSI interface and commands, and the DSI1 interface is recommended. 
dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-7inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-7inch,dsi0
  • 3. Insert the TF card into the Raspberry Pi, power it up, and wait for a few seconds for the display. Once the system boots up, you should be able to interact with it normally, including touchscreen functionality.

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://www.waveshare.com/w/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:

43H-800480-IPS07.GIF

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

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

Where 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:

DSI-LCD-Bookworm-Rotate-01.png

  • 2. Enter "Screen" -> "DS-1" -> "Touchscreen", and select "6-0038 generic ft5x06(79)".

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

  • 4. Enter "Screen" -> "DS-1"->"Orientation", and select the rotation direction. Then click on "Apply".

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

Bullseye/Buster Display Rptation

  • 1. Open "Screen Configuration" application:

DSI-LCD-Bullseye-Rotate-02.png

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

Stretch/Jessie Display Rotation

For some older systems, which do not use the vc4-kms-v3d or vc4-fkms-v3d driver modes, the display rotation method is as follows:

  • 1. Add statements to the config.txt file (the config file is located in the root directory of the TF card, i.e. /boot):
display_rotate=1 #1:90;2: 180; 3: 270
  • 2. Just save and reboot the Raspberry Pi:
sudo reboot

Touch Rotation

Some systems show inconsistent touch direction after rotation, requiring touch rotation as below:
1. Install libinput

sudo apt-get install xserver-xorg-input-libinput

2. If the system you installed is an Ubuntu system, or Jetson Nano, the installation command is:

sudo apt install xserver-xorg-input-synaptics

3. .Create the xorg.conf.d directory under /etc/X11/ (if this directory already exists, this goes directly to step 3):

sudo mkdir /etc/X11/xorg.conf.d

4. Copy "40-libinput-conf" file to the directory just created:

sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

5. Edit:

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf 
#Find the touchscreen part, add the corresponding commands to rotate, and then save:  
#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 rotation:
#Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
As shown below:

6. Reboot the Raspberry Pi:

sudo reboot

The touch will be rotated after completing the above steps.

Sleep

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

xset dpms force off

The above command is only for Bullseye and Buster systems.

Disable Touching

If you want to disable the touch function, you can modify the config.txt file, add the following line to the file, and reboot.

disable_touchscreen=1

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

FAQ


Anti-Piracy

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
