Function Documentation

bool mpu6050_init ( uint8_t  device_address)

Function for initializing MPU6050 and verifies it's on the bus.

Parameters
device_addressDevice TWI address in bits [6:0].
Returns
Return values
trueMPU6050 found on the bus and ready for operation.
falseMPU6050 not found on the bus or communication failure.
