Main function.

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize DIFF_P sensor driver.

Set the task to be executed while waiting for I2C transactions to complete.

Configure the DIFF_P sensor.

Check for both data ready bits from the DIFF_P.

Read new raw sensor data from the DIFF_P.

Explicitly clear the Status Bits.

Process the sample and convert the raw sensor data.
