3. Using with Raspberry Pi
3.1 Hardware Connection:
- Turn on the backlight switch located on the back of the screen.
- Connect one end of the FFC cable to the HDMI FFC connector on the screen and the other end to the HDMI adapter. Then secure the Raspberry Pi and finally plug the HDMI connector into the Raspberry Pi.
- Connect the USB cable between the Raspberry Pi and the screen.
- Connect the 3-pin cable between the Raspberry Pi and the screen.
- Connect the power adapter to the display to turn it on.
3.2 Software Setup
Supports Raspberry Pi OS, Ubuntu, Kali, and Retropie systems.
Connect the TF card to the PC.
Download and install the Raspberry Pi Imager from the Raspberry Pi official website.
Launch the imager, select the TF card you wish to write the image to (Note: It's best to remove any other USB storage devices to prevent accidental erasure of data).
Preconfigure the system settings by holding CTRL+SHIFT+X (or clicking the small gear icon in the bottom-right corner) and then save.
Click the write button to write the data to the TF card.
After writing is complete, open the /boot/firmware/ directory and append the following lines to the end of the config.txt file, then save and exit:
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
hdmi_driver=1Insert the TF card into the Raspberry Pi, power it up, and wait a few seconds for the display to initialize properly.
3.3 PWM Dimming
First, remove the 0 ohm resistor highlighted in red in the diagram below, then connect the external PWM signal to the GND pad on the screen.
