Software Setting

For Raspberry Pi OS/Ubuntu/Kali and Retropie systems.

  • 1. Insert the TF card into the PC, download it, and use Raspberry Pi Imager to program the corresponding image.

Pan-Tilt Camera WRITEIMAGE01.png

  • 2. After programming the image, open the "config.txt" file located in the root directory of the TF card. Add the following code at the end of config.txt, save the file, and safely eject the TF card.
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1920 720 60 6 0 0 0
hdmi_drive=2
  • 3. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds. After the system boots up, you should be able to enter the display interface and the LCD should touch normally.

Display Rotation

If you are using a Bullseye/Buster system, you can rotate it as follows:

  • 1. Go to Screen Configuration.

  • 2. Rotate as shown below:

If you use other systems, you can rotate the display as shown below:

  • 1. Add the following sentence in the config.txt file (the config file is located in the root directory of the TF card, or /boot):
display_rotate=1 #1：90；2: 180； 3: 270
  • 2. Reboot the Raspberry Pi after saving.
sudo reboot

Touch Rotation

As the touch direction is different after rotating, you need to rotate the touch as shown below:
1. Install libinput

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

If the system you want to install is Ubuntu or Jetson Nano, the installation command is:

sudo apt install xserver-xorg-input-synaptics

2. Create xorg.conf.d directory in /etc/X11/. (If the directory exists, you can directly skip to Step 3.) 

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

3. Copy 40-libinput-conf file to the directory created just now. 

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

4. Edit the file. 

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

Find the touchscreen part, add the following sentence, and then save. 

 Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

As shown below:

5. Reboot the Raspberry Pi. 

sudo reboot

After finishing the above steps, the touch can be rotated 90 degrees.

Note:
90-degree rotation: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
180-degree rotation: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
270-degree rotation: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"

Set the Screen Always On

Some customers want to display without being affected by the screen saver function and can be set as follows. Turn off the screen saver.
Open lightdm.conf. 

sudo nano /etc/lightdm/lightdm.conf

Change lightdm.conf to find "xserver-command" under the [SeatDefaults] section, uncomment it, and change it to read as follows:

#xserver-command=X

Modify to 

xserver-command=X -s 0 -dpms

-s # –: Set the screen saver not to enable.
dpms: Disable power saving management.
Reboot: 

sudo reboot

Set the Screen Off and On

Users can set the screen to turn off and on with the following commands. 

vcgencmd display_power 0
vcgencmd display_power 1
