How to simulate the ILI9341 TFT in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the ILI9341 TFT (catalog type ili9341).
Connect VCC and GND to the supply and ground of the board.
Connect SCK and MOSI to the SPI pins of the board.
Connect CS to the chip-select pin of the board, or to a free GPIO.
Connect LED to a pin that can output PWM.
Connect RESET and DC to free GPIO pins.
Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
