Hardware Connection

With an FFC cable, you can connect 43H-800480 to the DSI port of the Raspberry Pi. As shown below:

Software Setting

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

1. Please download the newest image from the Raspberry Pi official website. Download the compressed file to the PC, and unzip it to get the ".img" file.

2. Connect the TF card to the PC, and format the TF card with the SDFormatter.

3. Open Win32DiskImager software, choose the system image prepared in the first step, and click write to write the system image.

4. After writing, open the config.txt file in the TF card root directory. Add the following code at the end of config.txt, save it, and then safely remove the TF card.

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch

5. Insert the TF card into the Raspberry Pi, boot the Raspberry Pi, and enter to display after waiting for a few seconds. It can be normally touched after booting the system.

Backlight Control

Input the following commands on the terminal to adjust the backlight brightness:

echo X > /sys/class/backlight/10-0045/brightness

X means any numbers in 0~255. 0 means the darkest, and 255 means the brightest. For example:

echo 100 > /sys/class/backlight/10-0045/brightness
echo 0 > /sys/class/backlight/10-0045/brightness
echo 255 > /sys/class/backlight/10-0045/brightness

In addition, Waveshare provides the corresponding application demo (this demo is only for Raspberry Pi OS), users can install it and use it in the following ways:

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

After installing, you can open this demo in the Menu -> Accessories -> Brightness. As shown below:
