ST7789 1.3" 240x240

The ST7789 1.3" 240x240 is an SPI device in the LabWired part catalog. Its catalog type is st7789-240x240. It connects to the MCU over SPI. It has 7 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

From the catalog: SPI pixels and D/C are simulated via ST7789_KIT (twin type st7789-170x320). RES hardware reset is not simulated. No BLK pin on this module. Glass crop (col 0 / row 80) assumes MADCTL=0; rotated MADCTL is not remapped.

How to simulate the ST7789 1.3" 240x240 in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the ST7789 1.3" 240x240 (catalog type st7789-240x240).
  3. Connect GND and VCC to the supply and ground of the board.
  4. Connect SCL and SDA to the SPI pins of the board.
  5. Connect CS to the chip-select pin of the board, or to a free GPIO.
  6. Connect RES and DC to free GPIO pins.
  7. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
