How to simulate the APA102 DotStar Strip in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the APA102 DotStar Strip (catalog type apa102).
  3. Connect VCC and GND to the supply and ground of the board.
  4. Connect CI and DI 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 CO and DO as your circuit needs.
  7. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
