Software setting

  • Download image (Raspbian, Ubuntu, Kali or WIN 10 IOT) from the Raspberry Pi website. https://www.raspberrypi.org/downloads/
  • Unzip the archive to get .img file (The installation method of WIN 10 IOT is different, please refer to its website)
  • Insert your TF card to PC by card reader, format it firstly
  • Write the .img file to your TF card by Win32DiskImager or Etcher
  • After writing, insert the TF card to your Raspberry Pi
  • Power on Raspberry Pi

Rotation

To change the orientation of the display, you can modify /boot/config.txt file as below

  • Open the file
sudo nano /boot/config.txt
  • Modify it for rotating
  • 90°
display_lcd_rotate=1
dtoverlay=rpi-ft5406,touchscreen-swapped-x-y=1,touchscreen-inverted-x=1
  • 180
display_lcd_rotate=2
dtoverlay=rpi-ft5406,touchscreen-inverted-x=1,touchscreen-inverted-y=1
  • 270
display_lcd_rotate=3
dtoverlay=rpi-ft5406,touchscreen-swapped-x-y=1,touchscreen-inverted-y=1

If you use Raspberry Pi 4, you need to remove the line: dtoverlay=cv4-fkms-V3D

  • Save and reboot Raspberry Pi
