Driver Installation

This LCD Module need install driver first.

Step 1：Download the Raspbian IMG

https://www.raspberrypi.org/downloads/raspbian/

Step 2: Burn the system image

If you don't know how to do that,you can refer to the Raspberry Pi office tutorial

Step 3: Open terminal(SSH) and install the driver on RaspberryPi

(tested on RaspberryPi 3B+,3B,2B,2B+,1B,ZERO)

Run:

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.

Touch screen calibration

This LCD can be calibrated using a program called xinput_calibrator
Install it with the commands:

cd LCD-show/

sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb

Click the Men button on the task bar, choose Preference -> Calibrate Touchscreen.
Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).

/ect/X11/xorg.conf.d/99-calibration.conf

Save the touch parameters (may differ depending on LCD) to 99-calibration.conf, as shown in the picture:

How to rotate the display direction

Step 1，If the driver is not installed, execute the following command (Raspberry Pi needs to connected to the Internet):

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

After execution, the driver will be installed.

Step 2，If the driver is already installed, execute the following command:

cd LCD-show/
sudo ./rotate.sh 90

After execution, the system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
（ ' 90 ' can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）
If the rotate.sh prompt cannot be found, use Step 1 to install the latest drivers

Images download

If you have difficulty installing the driver, or if you still can't use the display properly after installing the driver,

Please Try our Configned images for tested.

Just need download and write the image into the TF card. DO NOT need any driver installation steps.
