Hardware connection

Please connect the LCD to your Raspberry Pi by the 8PIn cable according to the table below

Connect to Raspberry Pi
LCD Raspberry Pi
BCM2835 Board
VCC 5V 5V
GND GND GND
DIN MOSI 19
CLK SCLK 23
CS CE0 24
DC 25 22
RST 27 13

The color of actual cable may be different with the figure here, please connect them according to the pins instead of color. LCD RPI Connet.png

Enable SPI interfaces

  • Open terminal, use command to enter the configuration page

sudo raspi-config Choose Interfacing Options -> SPI -> Yes to enable SPI interface RPI open spi.png 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

  1. 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

  1. You will get 2.52 information if you install it correctly
  • Install Python libraries
  1. 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

  1. 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 LCD rpi python examples.png You can check all the files which are listed in type: 0inch96_LCD_test.py     0.96inch LCD example 1inch14_LCD_test.py 1.14inch LCD example 1inch28_LCD_test.py 1.28inch LCD example 1inch3_LCD_test.py 1.3inch LCD example 1inch54_LCD_test.py 1.54inchLCD example 1inch8_LCD_test.py 1.8inch LCD example 2inch_LCD_test.py 2inch LCD example
