    Hi,

    Pls make sure the hardware connection is fine. Then use following commands:

    i2cdump -y -f 0 0x38
0 is i2c bus no
0x38 is 7-bit i2c device address

    One more thing, what the 7-bit i2c address on your device? It seemed 0x70, this address is so strange, 
    kindly check the datasheet and hardware engineer.
