5. Arahan Operasi

After successfully connecting the module, you can begin programming your microcontroller to read data from the sensor.

5.1 Software Libraries and Code

• For Arduino-based systems, specific libraries are required to interface with the MCU-20948-001 (ICM-20948) sensor. Cari untuk "ICM-20948 Arduino library" in the Arduino IDE Library Manager or online.
• The register map and communication protocols for the ICM-20948 differ from older sensors like the MPU-9250. Ensure you use libraries and code specifically designed for the ICM-20948 to avoid compatibility issues.
• Refer to the documentation provided with your chosen library for example code and detailed usage instructions.

5.2 Pemerolehan Data

Once the library is integrated, you can initialize the sensor and read accelerometer and gyroscope data. The sensor provides raw data which may require calibration and filtering for accurate motion tracking.

• Accelerometer: Measures linear acceleration along X, Y, and Z axes.
• Giroskop: Measures angular velocity (rotation rate) around X, Y, and Z axes.

6. Penyelenggaraan

The MCU-20948-001 sensor module is a low-maintenance device. Follow these guidelines to ensure its longevity:

• Pastikan modul bersih dan bebas daripada habuk dan kelembapan.
• Elakkan daripada mendedahkan modul kepada suhu yang melampau atau cahaya matahari langsung.
• Handle the module with care to prevent physical damage to the components or solder joints.
• Ensure proper ventilation if enclosed in a casing to prevent overheating.

7. Penyelesaian masalah

If you encounter issues with your MCU-20948-001 module, consider the following common problems and solutions:

• Module Not Responding / No Data:
  • Verify power connections (VCC and GND) and ensure the voltage is between 1.71V and 3.6V. A 5V supply will damage the module.
  • Check communication wiring (SCL, SDA for I2C; SCL, SDA, ADO, NCS for SPI) for correct connections and continuity.
  • Confirm the correct I2C address (0x68 or 0x69) is being used in your code.
  • Ensure the correct software library for the ICM-20948 is installed and properly configured. Libraries for MPU-9250 are not compatible.
• Bacaan Tidak Tepat:
  • Perform sensor calibration routines if available in your chosen library.
  • Ensure the module is securely mounted and not subject to vibrations or external magnetic interference (if using a magnetometer, though this module is 6-axis).
• Magnetometer Not Working (if applicable):
  • While this product is advertised as 6-axis, some ICM-20948 chips include a magnetometer. If your specific chip has one and it's not working, ensure the magnetometer is enabled and correctly addressed in your software. Some breakout boards might not expose all 9-axis functionality or require specific initialization.

8. Maklumat Keselamatan

• Jangan melebihi vol operasi yang ditetapkantage (1.71V to 3.6V). Overvoltage will damage the module.
• Avoid short-circuiting the pins.
• Keep the module away from water, corrosive liquids, and extreme temperatures.
• This product contains small components and should be kept out of reach of children.
• If you are unsure about any connection or operation, consult relevant technical documentation or seek professional assistance.
