Raspberry 3.5in screen Manual

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

This method only applies to the Raspberry Pi series of display screens, other display screens do not apply.

• Method 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 ./XXX-show 90

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
（ ' XXX-show ' can be changed to the corresponding driver, and ' 90 ' can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）

• Method 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 Method 1 to install the latest drivers
