Touch Settings on Win 10 PC

Some users want to connect more than one display to their PC. Here we talk about how to setting the touch to make the touchscreen to control its screen separately.

• Connect touchscreen to PC. Here we use an standard PC monitor and connect an 7inch HDMI LCD (C) for example. We make the monitor as main screen and the touchscreen as secondary screen.
• By default,The touchscreen can only control cursor on the main screen. Here we set it to control the secondary screen
• Open Control Panel and search Tablet PC setting on the control panel and open the tool

• Click button "Setup..." to setting the touchscreen

• After click the setup you can find that there is prompt on your first screen with white color background and other screens are white.

• If we want the touch of the touchscreen to control the desktop of the touchscreen itself. Just press Enter key to pass the first screen. And the second screen, when you find that the black text is displayed on the touchscreen, just touch the center of the touchscreen to finish this setting.

• After this setting, the touch on the screen will just control this touchscreen even thought it is not the main screen.

Note:

1 If the first screen and the second screen are touchscreen as well, you can touch them when the text is displayed on the screens. Then you can find that all the touchscreen can work.

2 This method is just tested on win 10 PC.

Working with Raspberry Pi

Supports Raspbian/Ubuntu mate/Windows 10 iot Core

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

Download the Raspbian image from Raspberry Pi web site. Write the image to a TF card and append the following lines to the config.txt file which is located in the root of your TF card:

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

If you use the LCD with Raspberry Pi 4B, you need to remove line dtoverlay=vc4-fkms-V3D from config.txt file

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

Connect the Touch interface of LCD to USB port of Raspberry Pi

Connect HDMI interface of LCD to HDMI port of Raspberry Pi

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

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.

Rotation

Note: To rotate the touch, you can re-compile the kernel as well. There is an example for reference (use 7inch HDMI LCD (C).)

Display Rotating

To rotating the display, you can append this statement to the config file

display_rotate=1 #1: 90; 2: 180; 3: 270

Reboot the Raspberry Pi

sudo reboot

Touch rotating

With the operation above. The screen could rotate in display. However, the touch works improperly. To rotate the touch as display, you could do as below:

1. install libinput

sudo apt-get install xserver-xorg-input-libinput

2. create an xorg.conf.d folder

sudo mkdir /etc/X11/xorg.conf.d

3. copy file 40-libinput-conf to the folder which we created

sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

4. Append a statement to touchscreen part of the file as below:

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

5. save and reboot your Pi

sudo reboot

After completing these steps. The LCD could rotate 90 degree both display and touch.

Note:

90 degree: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

180 degree: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

270 degree: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"

Working with Jetson Nano

To work with Jetson Nano Developer Kit, you just need to connect the LCD and power on

• Connect the Touch interface of the LCD to USB port of Jetson Nano
• Connect the HDMI interface of the LCD to HDMI port of Jetson Nano
• Power on the Jetson Nano and the LCD can display after several seconds.
