1.3 inch LCD HAT

1.3” LCD HAT is a 1.3-inch diagonal display HAT with 240 x 240 resolution, 65K RGB colors, clear and colorful displaying effect, Four Push buttons and a joystick, designed for the Raspberry Pi to expand its engagement via SPI communication by providing a standard 40 pin GPIO interface. The 1.3" LCD HAT includes an integrated ST7789VM display driver and SPI interface, reducing the number of IO pins required. It features a 5-input joystick that is internally connected through a stackable GPIO connector header.

Installation

Python

Open a terminal and run the following commands to enable SPI：

sudo raspi-config

Choose Interfacing Options -> SPI -> Yes

You can also use GUI method to enable SPI Go to Menu > Preferences > Raspberry Pi Configuration > Interfaces, and enable SPI

Stack 1.3 inch LCD HAT on top of Raspberry Pi GPIO Header pins.
Make Sure SPI is Enabled (As mentioned above)
Now clone 1.3 inch LCD HAT Github repository by running below command in terminal

git clone https://github.com/sbcshop/1.3-LCD-HAT.git

Enter dowloaded directory

cd 1.3-LCD-HAT

Now run main.py by running the below command. It will display some text and an image on LCD.

python3 main.py

You can also run "Button_demo.py" file to test joystick and buttons.

python3 Button_demo.py
