Driver Installation
Step1,Install the Raspbian/UbuntuMate official mirror (Q:How to?)
- (1) Download the latest Raspbian/ubuntumate mirror from official
- (2) Use <SDFormatter> to format Micro SD card
- (3) Use <Win32DiskImager> to burn the official image to Micro SD card
Step2,Connect with RaspberryPi
- Align right-side to insert the LCD screen
- Plug-in MicroSD card, connect network and power
Step3,Install Driver for RaspberryPi
- (1)Login to raspberryPi terminal by SSH (user name: pi ,password :raspberry) (Q:How to?)
- (2)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 ./MHS40-show
- (3) After the above commands are executed, the system will automatically restart and be able to display and touch normally now.
- Note: after installing this driver, the HDMI output will be disabled. If it is necessary to switch back to the HDMI display, execute:
sudo ./LCD-hdmi
