  • Connect the TF card to the PC, and use the SDFormatter to format the TF card.
  • Open Win32DiskImager file, select the system image prepared by the first step and click 'Write' to write the system image.
  • After writing, open the config.txt file located in the boot directory of the TF card. Add the following code at the end of config.txt, save, and then safely remove the TF card.
hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 220 32 110 1280 0 10 10 10 0 0 0 60 0 59510000 0
  • Connect the TOUCH interface of the LCD to the USB interface of the Raspberry Pi.
  • Connect the HDMI interface of the LCD to the HDMI interface of the Raspberry Pi. Power on the Raspberry Pi, and then normally display after a few seconds.

Note: The default orientation of the display is vertical with 480x1280 hardware. If you want to change it to horizontal, you can refer to the #Display Orientation.

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
