Technical overview

  • Resolution: 172 x 320 pixels; IPS type
  • Supply voltage: 3.3 V or 5 V; supply and logic voltages must match
  • Interface: 4-wire SPI; ST7789V3 supports RGB444/RGB565/RGB666 color formats
  • Connection to Raspberry Pi via PH2.0 8-pin cable per pin mapping table
  • Example programming for STM32F103RBT6 with provided pin mapping
  • Arduino UNO pin mapping available
  • SPI mode 0 (CPHA=0, CPOL=0) is commonly used
  • Python demos run without additional library installation on Bookworm

Commands and examples – verify before use: 

sudo raspi-config
sudo reboot
sudo ./main 1.47
sudo python3 1inch47_LCD_test.py

Notes and version constraints

  • Pin mappings are device-specific; adapt them for other boards
  • The FBCP porting replaces /boot/config.txt and /etc/rc.local - back them up first
  • Version-sensitive steps: BCM2835/wiringPi are unavailable on Bookworm, only lgpio
  • Maximum brightness 380 cd/m² and current draw 47 mA apply at 3.3 V only
