Question:
How to apply the RPi LCD in a custom Raspbian system mirror image?
Answer:

Configure your Pi:

sudo raspi-config
  • Select Expand Filesystem.
  • You should make sure the custom mirror image used can boot to desktop. Check the configuration: Enable Boot to Desktop/Scratch -> Desktop Log in as user 'pi' at the graphical desktop

Download LCD-show-YYMMDD.tar.gz and extract it. Copy the file LCD-show.tar.gz into your custom mirror image via the network or an U disk. Run the following commands:

tar xvf LCD-show.tar.gz
cd LCD-show/
  • For 3.2inch RPi LCD (B), run the command:
sudo ./LCD32-show
  • For 3.5inch RPi LCD (A), run the command:
sudo ./LCD35-show
  • For 4inch RPi LCD (A), run the command:
sudo ./LCD4-show
  • For 5inch HDMI LCD, run the command:
sudo ./LCD5-show

Then, wait a few minutes, the system will restart automatically. When finished, the RPi LCD is ready to use.
