Working with Raspberry Pi

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems. When the LCD works on systems such as Raspberry Pi, the resolution must be set manually, otherwise, it will cause an abnormal display. There is no such problem when the LCD works on the PC version of Windows.

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

1. Download the compressed file to the PC, and extract the img file.
2. Connect the TF card to the PC and use SDFormatter to format the TF card.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
4. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, and save it.

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

You must ensure that there are no spaces around the equal sign.
5. Insert the TF card into the Raspberry Pi and turn on the backlight switch on the back of the LCD.
6. Connect the Touch port of the LCD to the USB port of the Raspberry Pi.
7. Connect the HDMI port of the LCD to the HDMI port of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds to display normally.

Calibration in Raspbian

Install related software:

sudo apt-get install xinput-calibrator
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot
  • There will be an additional Calibrate Touchscreen in Menu->Preferences, run the demo to calibrate.
  • Perform touch calibration according to the displayed prompt. After calibration, there should be a good touch effect (if the error is relatively large, you can re-run the calibration procedure).
  • If you want to save these touch values, you need to create a new 99-calibration.conf file in the following path:
/etc/X11/xorg.conf.d/99-calibration.conf
  • Save information similar to the following to 99-calibration.conf.

 Answer:
When the Raspberry Pi is powered by a 5V 2A power adapter and connects to 5inch HDMI LCD (H), it doesn’t require an external power supply by default. However, if the user uses the Raspberry Pi to drive other high-power devices at the same time, the USB interface on the Raspberry Pi may be insufficiently powered, at this time an external power supply is required.

Anti-Piracy

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:

Beware of knock-offs

Please note that we've found some poor copies of this item in the market. They are usually made of inferior materials and shipped without any testing.

You might be wondering if the one you're watching or you've purchased in other non-official stores is original, feel free to contact us.
