MMA8451Q Accelerometer

The MMA8451Q Accelerometer is an I²C device in the LabWired part catalog. Its catalog type is mma8451q. It connects to the MCU over I²C at the default address 0x1C. It has 8 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 MMA8451Q Accelerometer in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the MMA8451Q Accelerometer (catalog type mma8451q).
  3. Connect VCC and GND to the supply and ground of the board.
  4. Connect SDA and SCL to the I²C data and clock pins of the board.
  5. Connect I2, I1, 3V3 and SA0 as your circuit needs.
  6. Run the firmware. It finds the part on the I²C bus at 0x1C and reads and writes it as on hardware.
