5 inch Resistive Touch Screen LCD, HDMI interface, supports various systems
{{{name2}}}

{{{name3}}}

{{{name4}}}

{{{name5}}}

Introduction

5-inch Resistive Touch Screen LCD, with a resolution of 800 × 480, supports Raspberry Pi and can also be used as a computer monitor.

More

Features

  • 800 x 480 hardware resolution.
  • Resistive touch control.
  • Using Raspberry Pi, it supports Raspberry Pi OS / Ubuntu / Kali and Retropie system.
  • Using as a computer monitor, it supports Windows 11/ 10 / 8.1 / 8 / 7.
  • Support backlight control, more power saving.

Video

Working with PC

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

1) Turn on the backlight switch on the back of the LCD.

2) 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.

3) Connect the HDMI interface of the LCD to the HDMI interface of the PC.

Normally you can see an interface similar to the following figure. (Some PCs may need to be restarted to display.)

Calibration touch on Win 10 PC

Take the windows10 system as an example:

  • 1. Enter the Windows settings of the system, type in the search bar, and click "Calibrate the screen for pen or touch input" (as shown in the picture below).

Win10 touch011.png

Win10 touch02.png
  • 2. Click "Setup" in the pop-up "Tablet PC Settings" interface:


  • 3. The following text prompt will appear on the screen. Please tap the touch screen with your finger, and the computer will recognize it as a touch screen.

【Note】If the touch screen is blank, press the "Enter" key, and the text prompt will switch to the touch screen. (The screen which displays the text prompt will be used as a touch screen!)

Win10 touch03.png

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.

Raspberry Pi Long-press Right-click Software Installation

Test environment: 2022-04-04-raspios-bullseye-armhf 32-bit system
Supported models: Support Waveshare DSI LCD, DPI LCD, and HDMI LCD capacitive touch screen series.

Software Installation

wget https://files.waveshare.com/upload/1/18/Evdev-right-click-emulation.zip
unzip Evdev-right-click-emulation.zip
cd evdev-right-click-emulation
sudo apt install build-essential libevdev2 libevdev-dev
cd 'evdev-right-click-emulation'
sudo cp 'out/evdev-rce' '/usr/local/bin/'
sudo chmod +x '/usr/local/bin/evdev-rce'

Enter the command:

sudo evdev-rce

After running, you can touch and long press to realize the right-click function.

Set IP

sudo usermod -G 'input' -a pi
echo 'uinput' | sudo tee -a /etc/modules
sudo nano  /etc/udev/rules.d/99-uinput.rules

Add in 99-uinput.rules file.

KERNEL=="uinput", MODE="0660", GROUP="input"

save it and run it in the terminal.

sudo udevadm control --reload-rules
sudo udevadm trigger

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.
