// - Part1: Instantiate i2c peripheral
// - Part1: Implement one sensor, print sensor values
// - Part2: Implement second sensor on same bus to solve an ownership problem

    // 1. Instantiate the SDA and SCL pins, correct pins are in the training material.

    // 2. Instantiate the i2c peripheral,I2cDriver, using a I2cConfig of 400kHz

    // 3. Create an instance of the SHTC3 sensor.

    // 4. Read and print the sensor's device ID.
