===== Install =====
  - Download from https://www.raspberrypi.org/downloads/raspbian/
  - command <code bash>`sudo dd bs=4M if=2019-09-26-raspbian-buster-lite.img of=/dev/sdX conv=fsync`</code>

===== Enable ssh over USB @ Raspberry pi =====
at sd- "boot" partition
  - add ssh file <code bash>touch ssh</code>
  - in config.txt should append <code> dtoverlay=dwc2 </code>
  - in cmdline.txt should add after rootwait <code>modules-load=dwc2,g_ether</code> 
  - plug the usb, do ssh <code bash>ssh pi@raspberrypi.local</code> default user: **pi**, default password: **raspberry**

===== 1st time config =====
<code>
sudo raspi-config
</code>

 How to use it with Raspbian system

 

This LCD Module need install driver first.

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

Run:
<code bash>
sudo rm -rf LCD-show

git clone https://github.com/goodtft/LCD-show.git

chmod -R 755 LCD-show

cd LCD-show/

sudo ./LCD35-show

# Wait A Few Minutes, when the system reboot ok, you can see that.

</code>

==== Touch screen calibration ====
This LCD can be calibrated using a program called xinput_calibrator

1. Install it with the commands :
<code bash>
cd LCD-show/
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
</code>
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`

  
==== Trableshooting ====
you should install X server on "light" version of rpi
<code bash>
sudo apt-get --no-install-recommends install xserver-xorg xserver-xorg-video-fbdev xinit pciutils xinput xfonts-100dpi xfonts-75dpi xfonts-scalable
</code>

sudo vi /etc/X11/xorg.conf
<code text>
