ADXL345 accelerometer

The ADXL345 accelerometer is an SPI device in the LabWired part catalog. Its catalog type is adxl345_spi. It connects to the MCU over SPI. The catalog gives a supply range of 2–3.6 V. It has 6 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the ADXL345 accelerometer in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the ADXL345 accelerometer (catalog type adxl345_spi).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2–3.6 V.
  4. Connect SCK, SDI and SDO to the SPI pins of the board.
  5. Connect CS to the chip-select pin of the board, or to a free GPIO.
  6. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
