Initialization

Initialization steps are following:

1. Define needed functions and pass their pointers (See: porting guide).

2. Create mpu925x_t struct instance with initial values (See: accelerometer, gyroscope and magnetometer).

3. Call mpu925x_init() function with created mpu925x_t struct and AD0 pin values.

mpu925x_init() Function

Init function takes mpu925x_t struct and AD0 pin values as parameters. AD0 pin value depends on physical sensor and is most probably 0. See api reference for more info.

Init function will return 0 on success, 1 on accelerometer and gyroscope fail and 2 on magnetometer fail. One can use accelerometer and gyroscope with return value of 2. But with return value of 1, nothing works, so check wiring and sensor damage.
