How to use

Working with Windows PC

This LCD can support Windows 11 / 10 / 8.1 / 8 / 7 system.

1) Connect the TOUCH interface of the LCD to the USB interface of the PC. Wait for a while, the windows will automatically recognize the touch function.

2) Connect the HDMI interface of LCD to the HDMI port of the PC. About 10s later, you can see the LCD display properly. If you need the audio, you can insert 3.5mm earphones to HP ports, or connect to the related speaker module through the speaker interface (such as 8 ohms 5-watt speaker).

Note: When the computer is connected to several different displays at the same time, only this LCD can be used to control the cursor on the main display, so we recommended setting this LCD as the main display.

Working with Raspberry Pi

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems.

Please download the latest version of the image on the Raspberry Pi official website.

1) Download the compressed file to the PC, and unzip it to get the .img file.

2) Connect the TF card to the PC, use SDFormatter software to format the TF card.

3) Open the Win32DiskImager software, select the system image downloaded in step 1, and click‘Write’ to write the system image.

4) After the image has finished writing, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, then save and quit the TF card safely. 

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

5) Insert the TF card into the Raspberry Pi

6) Connect the Touch interface of the LCD to the USB interface of the Raspberry Pi.

7) Connect the HDMI interface of the LCD to the HDMI interface of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds until the LCD displays normally.

 gpio -g pwm 18 0
 gpio -g mode 18 pwm (occupied pins are PWM pins)
 gpio pwmc 1000
 gpio -g pwm 18 X (X ranges from 0 to 1024), 0 is the brightest, 1024 is the darkest
