What's ON Board

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.

Working with PC

This product supports Windows 10/8.1/8/7 OS.:
1. Connect the TOUCH interface of 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 5s later, you can see the LCD display properly. If you need the audio, you can insert 3.5mm earphones into HP ports.
Note:
1) 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.
2) Some of PC cannot support the HDMI screen Hot Plug. In this case, restarting the PC can solve.
3) Sometimes LCD will flicker because of undersupplying from USB cable of PC. You need to connect an external power supply (5V/2A) to the DC port.
4) HP audio output only works while using HDMI communication
5) Mini HDMI to VGA Cable is necessary and needs to be purchased separately if you use VGA communication.

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

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

Win10 touch02.png


  • 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!)

Working with Raspberry Pi

Supports Raspberry Pi OS/Ubuntu/Kali/Retropie/Windows 10 IoT Core

When working with Raspberry Pi, you should set the resolution of the LCD by yourself, otherwise, the LCD screen will not work. For more detailed information, please read the following section.

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.exe software to format the TF card.

3) Open the Win32DiskImager.exe 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, and comment out dtoverlay=vc4-fkms-V3D.

5) Add the following code at the end of config.txt, then save and eject the TF card safely.

max_usb_current=1
hdmi_force_hotplug=1 
config_hdmi_boost=10
hdmi_group=2 
hdmi_mode=87 
hdmi_cvt 1024 600 60 6 0 0 0

You must make sure that there are no spaces on either side of the equal sign.

6) Save and connect the TF card to your Pi then power up.

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

8) Connect the HDMI interface of LCD to the HDMI port of Raspberry Pi.


Note:

  • Resolution of Ubuntu Mate OS or Windows 10 IoT Core OS can also be set properly by editing config.txt.
  • For Pi Zero / Zero W: if you've used an SD card on a Pi 3 and then attached the card to the Pi Zero, the touch screen often doesn't work. In such cases, you have to write a fresh system image to the SD card. The first boot up must be done on the Pi Zero but not Pi 3, due to initialization for a corresponding device.
  • On December 2, 2021, the Raspberry Pi OS was divided into two branches, the Buster branch and the Bullseye branch. The Buster branch is a continuation of the old system and is more stable. The Bullseye branch added some new features, using open source libraries and new interfaces. Since the current Bullseye branch has just been released shortly, it is not stable yet. If you are an industrial user, it is strongly recommended to use the Buster branch.
  • If you use the Buster branch system, you can use it according to the above configuration. But if you are using the Bullseye branch system, you need to modify the default KMS driver to FKMS driver to display the system desktop normally

Modification method: Open the config.txt file in the root directory of the TF card, find the following line:

 dtoverlay=vc4-kms-v3d

change into

 dtoverlay=vc4-fkms-v3d
  • If you need to use the CSI camera under the Bullseye branch system. Since this branch uses the libcamera camera library by default, the library doesn't support FKMS drivers.

So in addition to the above modification, you also need to install the Raspicam camera library.

The installation method is as follows:

 cd ~
 sudo apt install cmake
 git clone https://github.com/raspberrypi/userland
 cd userland
 ./buildme
 sudo cp build/bin/* /bin/

Then execute the following command to shut down the system:

 poweroff

Connect the Raspberry Pi camera to the CSI interface of the Raspberry Pi, power on the Raspberry Pi again, and after the system boots, execute the following command:

Take a picture:

 raspistill -o image.jpg

Take a video:

 raspivid -o video.h264 -t 10000

Backlight adjustment on Raspberry Pi OS

  • 2. Enter the corresponding directory of this file in the terminal and run the command as follows:
 ./7HP_Backlight -b  X      # X range is 0~10, 0 is the darkest, 10 is the brightest

For example:

 ./7HP_Backlight -b  3

Working with Jetson Nano

To work with Jetson Nano Developer Kit, you don’t need to make software configurations.

1) Connect the TOUCH interface of the LCD to the USB interface of Jetson Nano.

2) Connect the HDMI interface of the LCD to the HDMI interface of the Jetson Nano and then power on the Jetson Nano. After about 5 seconds, you can see the LCD display normally. If you need to output sound, you can insert 3.5mm earphones into the HP audio output interface.

Note:

1) If the LCD flickers, it may be due to the insufficient power supply of the Jetson Nano's USB interface. It can be solved normally after connecting to an external 5V/2A power supply through the DC interface of the LCD.

2) When the HP audio interface is in use, it may be necessary to set the sound output settings in the system.

FAQ

Question:
What should I do if I connect to the PC with LCD and it cannot display normally?
Answer:

  • The PC only connects to this LCD as a monitor without others.
  • You should connect the touch cable first and then the HDMI cable.
  • Some PC need to be restarted to make the 7inch HDMI LCD display normally.

Note: The PC must use a windows system.
