NeoPixel 8x8 Matrix

The NeoPixel 8x8 Matrix is an SPI device in the LabWired part catalog. Its catalog type is neopixel-matrix. It connects to the MCU over SPI. The catalog gives a supply range of 5 V. It has 4 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: WS2812 8x8 matrix: same edge decoder as neopixel with num_pixels=64. Canvas shows columns/zigzag/top-left grid; core stores a linear strip.

How to simulate the NeoPixel 8x8 Matrix in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the NeoPixel 8x8 Matrix (catalog type neopixel-matrix).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 5 V.
  4. Connect DIN and DOUT as your circuit needs.
  5. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
