Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Waveshare 1.3-inch LCD module uses an ST7789VW controller, an IPS panel with 240x240 resolution and an SPI interface. It operates at 3.3 V or 5 V and is intended for Raspberry Pi, STM32, Arduino and VisionFive2.

Technical overview

  • Resolution: 240 x 240 pixels; display area approx. 23.4 mm x 23.4 mm; pixel pitch 0.0975 mm.
  • Controller: ST7789VW (supports RGB444, RGB565, RGB666); demos use RGB565.
  • Interface: 4-wire SPI (MOSI/DIN, SCLK/CLK, CS, DC, RST, BL).
  • Raspberry Pi wiring: VCC to 3.3 V, GND, DIN to MOSI (pin 19), CLK to SCLK (pin 23), CS to CE0 (pin 24), DS/DC to pin 22, RST to pin 13, BL to pin 12.
  • STM32 example based on STM32F103RBT6: DIN→PA7, CLK→PA5, CS→PB6, DC→PA8, RST→PA9, BL→PC7.
  • Arduino UNO example: DIN→D11, CLK→D13, CS→D10, DC→D7, RST→D8, BL→D9, VCC→5 V.
  • SPI protocol: CSX low enables the device; D/CX = 0 writes commands, D/CX = 1 writes data; default mode SPI0 (CPHA=0, CPOL=0).
  • Raspberry Pi: enable SPI via raspi-config (Interfacing Options → SPI → Yes), then reboot.
  • On Bookworm only lgpio is available; bcm2835 and wiringPi cannot be installed there.
  • VisionFive2 pins match the Raspberry Pi table: DIN→19, CLK→23, CS→24, DC→22, RST→13, BL→12.

Commands and examples – verify before use:  

sudo raspi-config
sudo reboot
sudo wget https://files.waveshare.com/upload/8/8d/LCD_Module_RPI_code.zip
sudo unzip ./LCD_Module_RPI_code.zip
cd LCD_Module_RPI_code/RaspberryPi/c
sudo make clean && sudo make -j 8
sudo ./main 1.3
cd ../python/examples
sudo python3 1inch3_LCD_test.py
apt-get install pip
pip install VisionFive.gpio
wget https://files.waveshare.com/upload/e/e9/LCD_Module_code.7z
7z x LCD_Module_code.7z -o./LCD_Module_code
cd LCD_Module_code/VisionFive/python/example/
python3 1inch3_LCD_test.py

Notes and version constraints

  • Different Linux versions support different libraries; e.g., FBCP does not work on Bookworm – Bullseye is recommended.
  • Power supply must match the logic voltage (3.3 V or 5 V), otherwise the module will not operate correctly.
  • For Arduino, a stable 5 V power supply must be connected, otherwise the display may malfunction.
  • Pin mappings can vary by development board; verify actual pins before soldering.
  • Version-sensitive steps: demo downloads and library installations depend on the operating system used.
  • Accuracy of pin assignments and compatibility should be confirmed by a technician before integration.
