==Enable SPI interfaces==
*Open terminal, use command to enter the configuration page
sudo raspi-config
Choose Interfacing Options -> SPI -> Yes  to enable SPI interface
[[file:RPI_open_spi.png|900px]]
Reboot Raspberry Pi：
sudo reboot
Please make sure that SPI interface was not used by other devices 

==Install Libraries==
*Install BCM2835 libraries
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.68.tar.gz
tar zxvf bcm2835-1.68.tar.gz 
cd bcm2835-1.68/
sudo ./configure
sudo make
sudo make check
sudo make install
#For more details, please refer to http://www.airspayce.com/mikem/bcm2835/
*Install wiringPi libraries
 sudo apt-get install wiringpi
For the version of the Raspberry Pi system after May 2019 (the OS version earlier than this date doesn't need to be executed), an upgrade may be required：
wget https://project-downloads.drogon.net/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb
gpio -v
#You will get 2.52 information if you install it correctly
*Install Python libraries
#python2
sudo apt-get update
sudo apt-get install python-pip
sudo apt-get install python-pil
sudo apt-get install python-numpy
sudo pip install RPi.GPIO
sudo pip install spidev
#python3
sudo apt-get update
sudo apt-get install python3-pip
sudo apt-get install python3-pil
sudo apt-get install python3-numpy
sudo pip3 install RPi.GPIO
sudo pip3 install spidev

==Download Examples==
Open Raspberry Pi terminal and run the following command
sudo apt-get install p7zip-full
sudo wget  https://www.waveshare.net/w/upload/a/a8/LCD_Module_RPI_code.7z
7z x LCD_Module_RPI_code.7z -O./LCD_Module_code
cd LCD_Module_code/RaspberryPi/

==Run the demo codes==
Please go into the RaspberryPi directory (demo codes) first and run the commands in terminal

===C codes===
*Re-compile the demo codes
cd c
sudo make clean
sudo make -j 8
This examples are made for multi-dusplay, you can input the type of the LCD when using.
sudo ./main <>
Use the command according to LCD:：
sudo ./main 0.96
sudo ./main 1.14
sudo ./main 1.28
sudo ./main 1.3
sudo ./main 1.54
sudo ./main 1.8
sudo ./main 2

==python==
*Enter the python directory and run ls -al
cd python/examples
ls -l
