How to Use the Touch LCD
Step 1: Download the Raspbian image
https://www.raspberrypi.org/downloads/raspbian/
Step 2: Burn the system image to the SD card
https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up/3
Stop 3 : Connect the LCD to Raspberry Pi , insert the system SD card , connect the Ethernet and power on it
Step 4: Open terminal(SSH) and install the driver on RaspberryPi
(1)Execute the following commands (RaspberryPi needs to connect Internet):
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./MHS35-show
(2) After the above commands are executed, the system will automatically restart and be able to display and touch normally now.
Install LCD driver
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
- If Raspberry Pi is equipped with GPIO display drivers such as MPI2411, MPI2418, MPI2801, MPI3201, MPI3501, etc., the HDMI port will have no signal output
- If you need to switch back to the HDMI display mode, execute:
cd LCD-show/
sudo ./LCD-hdmi
Download LCD Driver Manually

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.
