/**
@brief The BMI160 is a small, low power, low noise 16-bit inertial measurement
unit designed for use in mobile applications like augmented reality or indoor
navigation which require highly accurate, real-time sensor data.
In full operation mode, with both the accelerometer and gyroscope enabled, the
current consumption is typically 950 μA, enabling always-on applications in
battery driven devices. It is available in a compact 14-pin 2.5 x 3.0 x 0.8 mm³
LGA package."
This class is an abstract base class and can not be instaniated, use BMI160_I2C
or BMI160_SPI.
