1. Hardware connection
1) Connect the DSI interface of 7inch DSI LCD to the DSI interface of Raspberry Pi through 15PIN FPC cable.
2) Use the 2PIN power cable to connect the power interface of the LCD to the 40PIN GPIO interface of the Raspberry Pi.
3) For easy use, you can fix the Raspberry Pi on the backside of the 7inch DSI LCD with screws.

2. Software setting
1) Download image from the Raspberry Pi website.
2) Download the compressed file to the PC, and unzip it to get the .img file.
3) Connect the TF card to the PC, use SDFormatter.exe software to format the TF card.
4) Open the Win32DiskImager.exe software, select the system image downloaded in step 2, and click ‘Write' to write the system image.
5) After the image has finished writing, save, and quit the TF card safely.
6) Power on the Raspberry Pi and wait for a few seconds until the LCD displays normally. And the touch function can also work after the system starts.

3. Backlight Controlling
1) Open a terminal and type the following command to adjust the brightness. Note: If the command reports the 'Permission denied' error, please switch to the 'root' user mode and execute it again.
echo X > /sys/class/backlight/rpi_backlight/brightness
X can be value in range 0~255. The backlight is darkest if you set it to 0 and the backlight is set to lightest if you set it to 255
echo 100 > /sys/class/backlight/rpi_backlight/brightness
echo 0 > /sys/class/backlight/rpi_backlight/brightness
echo 255 > /sys/class/backlight/rpi_backlight/brightness
