How to install: instruction
Please refer to How to assemble 10.1inch-HDMI LCD (B) holder
This product supports Windows 10/8.1/8/7 OS. For the Windows 10/8.1/8 OS, the touch screen supports multi-touch up to 10 points. For some Window 7 OS, the touch screen supports single touch only.
Please make sure the connections are done in a right sequence, or else the LCD may not work well.
Generally, you will see the screen displays the interface as the figure shows below. In this interface, slightly click the screen can perform the left-key mouse action, and long press the screen can perform the right-key mouse action. (You can also control the Back light of the screen with the back light adjustment button; see the mark 1 shows in the following figure.)
Take the windows10 system as an example:
【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!)
For the Windows OS on PC, the resolution of the LCD is automatically identified. Hence, you do not need to make the relative settings. 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.
At the beginning, you should download the latest image file, RASPBIAN or UBUNTU MATE, from the website: http://www.raspberrypi.org/downloads/.
max_usb_current=1 hdmi_group=2 hdmi_mode=87 hdmi_cvt 1280 800 60 6 0 0 0 hdmi_drive=1
If you use the LCD with Raspberry Pi 4B, you need to remove line dtoverlay=vc4-fkms-V3D from config.txt file
if the statements above do not work properly, replace them with the following lines:
max_usb_current=1 hdmi_group=2 hdmi_mode=27
If the LCD is used for Raspberry Pi and there are "ghost images" on the LCD, try to comment or delete this line in the config.txt to fix such cases:
hdmi_drive=2
Display Rotating
Add this statement in the config.txt file (the config file is located in the root directory of the TF card, which is named /boot):
display_rotate=1 #1:90;2: 180; 3: 270
Note: For Raspberry Pi 4, you need to comment out dtoverlay=vc4-fkms-V3D.
#dtoverlay=vc4-fkms-V3D.
And then restart the Raspberry Pi after saving.
sudo reboot
Touch Rotating
After the display is rotated, the position of touch is incorrect because the touch doesn’t change with the display angle. So the touch also needs to be modified.
1.Install libinput.
sudo apt-get install xserver-xorg-input-libinput
If the system you installed is Ubuntu or Jetson Nano. The installation code is:
sudo apt install xserver-xorg-input-synaptics
2.Create the xorg.conf.d directory under /etc/X11/ (if the directory already exists, proceed directly to step 3).
sudo mkdir /etc/X11/xorg.conf.d
3.Copy the 40-libinput-conf file to the directory you created just now.
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
4.Edit this file.
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
Find the part of the touchscreen, add the following statement inside, and then save the file.
Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
Similar to the picture below:
sudo reboot
After completing these steps. The LCD could rotate 90 degrees both display and touch function.
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"
