LCD Model

Got device from How to use it with Raspbian system

This LCD Module need install driver first.


Open terminal(SSH) and install the driver on RaspberryPi (tested on RaspberryPi 3B+,3B,2B,2B+,1B,ZERO)


sudo rm -rf LCD-show
git clone
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD35-show
# Wait A Few Minutes, when the system reboot ok, you can see that.

Touch screen calibration

This LCD can be calibrated using a program called xinput_calibrator

1. Install it with the commands :

cd LCD-show/
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb

2. Click the Men button on the task bar, choose `Preference → Calibrate Touchscreen.`

3. Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.

4. You can create a `99-calibration.conf` file to save the touch parameters (not necessary if file exists). `/etc/X11/xorg.conf.d/99-calibration.conf`

5. Save the touch parameters (may differ depending on LCD) to `99-calibration.conf`


you should install X server on “light” version of rpi

sudo apt-get --no-install-recommends install xserver-xorg xserver-xorg-video-fbdev xinit pciutils xinput xfonts-100dpi xfonts-75dpi xfonts-scalable

sudo vi /etc/X11/xorg.conf
