Instructions for Use:

1. Power Supply Setup:

   • Ensure the supply voltage is within the specified range of 1.71V to 3.45V.
   • Connect VDD and VDDIO to the appropriate power supply lines.

2. Communication Interface Configuration:

   • Select either I2C or SPI interface based on your application requirements.
   • For I2C, connect SDA and SCL lines to the corresponding pins on your microcontroller.
   • For SPI, connect MOSI, MISO, SCK, and CS lines accordingly.

3. Initialization:

   • Power up the device and ensure stable power supply before initializing communication.
   • Use a suitable library or write initialization code to set up the sensor according to your needs.

4. Setting Accelerometer and Gyroscope Ranges:

   • Configure the desired sensitivity range for both accelerometer and gyroscope using register settings.
   • Refer to the datasheet for specific register addresses and bit configurations.

5. Data Acquisition:

   • Read data from the sensor through the selected communication protocol.
   • Process the raw data into meaningful acceleration and angular velocity measurements.

6. Interrupts and Features:

   • Utilize built-in features like motion detection, FIFO buffer, and interrupts for advanced applications.
   • Configure interrupt pins and enable specific events as needed.

7. Handling and Storage:

   • Store in a dry, cool place when not in use.
   • Handle with care to avoid damage to the sensitive components.

For detailed register maps and more specific instructions, refer to the official ICM-20689 datasheet provided by TDK-InvenSense.
