CTL_STATUS_t adxl345_initialize_i2c(CTL_ACCELEROMETER_t *self, CTL_I2C_BUS_t *bus, int addr);
adxl345_initialize_i2c initializes the accelerometer interface self with methods to communicate with an ADXL345 accelerometer on the I2C bus bus with 8-bit I2C address addr.
Once the accelerometer interface is initialized, you can use all standard accelerometer methods from the sensor API on the interface.
adxl345_initialize_i2c returns a standard status code.
adxl345_initialize_i2c is thread-safe if a mutex is associated with the I2C bus bus.
