Hardware Configuration¶
The LCD module hardware circuit comprises two parts: an LCD display control circuit and a backlight control circuit.
The LCD display control circuit is used to control the pins of the LCD, including control pins and data transfer pins.
if the backlight is not required to be be on and off, can be directly connected to the 3.3V if the backlight is not required to be be on and off, can be directly connected to the 3.3V power supply.

Software¶
STEP1 Download 2.0inch_SPI_Arduino_Demo.zip
STEP2 Configure controller board&communication port
On top of the Arduino IDE, click “Tools>Board>” and select “Arduino Uno” from the available options
Select the COM port that indicates Arduino Uno. Please note that the actual numbers after the “COM” word will vary from computer to computer, so they could be different from the ones shown in the figure.
STEP3 Install libraries :Unzip Install libraries.zip and copy folder "LCDWIKI_GUI" and "LCDWIKI_SPI" to the libraries directory under the Arduino installation directory
STEP4 Load the program to Arduino IDE
STEP5 Click the 
to upload the code to the Crowduino board
STEP6 After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs successfully.
