    Adopted from i2c - Simple example

    Simple I2C example that shows how to initialize I2C
    as well as reading and writing from and to registers for a sensor connected over I2C.

    The sensor used in this example is a MPU9250 inertial measurement unit.

    For other examples please check:
    https://github.com/espressif/esp-idf/tree/master/examples

    See README.md file to get detailed usage of this example.
