Features

  • Resolution of 800×480
  • Resistive touch
  • Compatible and can be plugged into any Raspberry Pi (Raspberry Pi Zero / Zero 2 W requires its own HDMI cable)
  • Supports Raspberry Pi OS / Ubuntu / Kali and Retropie systems
  • Can be used as a computer monitor without touch function (additional HDMI cable is required to connect to computer)
  • Only for display, does not occupy any I/O resources (use touch function, occupy I/O)
  • Support backlight control, more power saving.


Hardware Connection

With the HDMI bridge board, connect the Raspberry Pi to the HDMI port of the display, and turn on the backlight control switch.

Note:
the Raspberry Pi Zero / Zero 2 W requires its own HDMI cable

Install Raspberry Pi OS

An operating system needs to be installed onto the Micro SD card before inserting it into the Raspberry Pi.

Note:
Skip this chapter if the Raspberry Pi already has an operating system installed.


Raspberry Pi Imager is a quick and easy way to install the Raspberry Pi operating system to a Micro SD card from a computer or laptop.

Browse to the Raspberry Pi Imager site and download the version that matches the computer or laptop\'s operating system (www.raspberrypi.org/software). When the download is complete, launch the installer program and follow the prompts to install the Raspberry Pi Imager.

3d1.png

If the Windows operating system prevents the application from launching, click on More info and then click on Run anyway to install the Raspberry Pi Imager.

3d2.png

Insert the Micro SD card into the computer or laptop's SD card slot. If the computer or laptop only has a full-size port for SD cards, use a Micro SD card adapter. In the Raspberry Pi Imager, click CHOOSE OS -> Raspberry Pi OS.

3d33.png


Select the SD card you are using.

3d4.png

Click the WRITE button.

3d5.png

After writing, open the config.txt file in the \boot directory of the TF card.

3d5.png

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

Note:
No spaces on either side of the = sign. 

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1
dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900

When you insert the TF card into the Raspberry Pi, power it up, and wait for a while, the Raspberry Pi will start normally. In this case, the touch may be faulty and needs to be calibrated.


Touch Calibration

The display can be calibrated with xinput-calibrator.

Execute the following command to install the relevant software. 

sudo apt-get update
sudo apt-get install xserver-xorg-input-evdev xinput-calibrator

Copy the contents of 10-evdev.conf to 45-evdev.conf, then open the 99-calibration.conf file. 

sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo nano /usr/share/X11/xorg.conf.d/99-calibration.conf

Add the following code to the 99-calibration.conf file. 

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "208 3905 288 3910"
        Option  "SwapAxes"      "0"
        Option "EmulateThirdButton" "1"
        Option "EmulateThirdButtonTimeout" "1000"
        Option "EmulateThirdButtonMoveThreshold" "300"
EndSection

Touch will work normally after restarting the Raspberry Pi. With different resistive screens, the accuracy may not be very good using the default calibration parameters, so you need to follow the guide below.

On the touch screen, click on Menu -> Preference -> Calibrate Touchscreen. 

Inch2.jpg

Then the screen will show 4 points. You need to tap them one by one to calibrate.

Inch3.jpg

You will get the following results after calibration. Please copy the contents of the red box. 

Inch4.jpg

Open the 99-calibration.conf file again. 

sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

Paste the copied text into the file. You can save the file by pressing 'Ctrl+X', selecting 'Y', and then pressing 'Enter'.

Reboot the Raspberry Pi again and you will see that the touch screen is working properly.
