Pololu I2C fails


this is Santhananarayanan.

I am working with Analog devices ADuCm360 with Pololu AltiMU 10 v4 to read accelerometer value through I2C.

I am using the addresses 0x3a(to write) and 0x3b(to read) and the registers 0x28,29,2a,2b,2c,2d.
but I am not receiving the data from polulu. Even I can’t receive proper ack signal.

help me to solve.


I am sorry you are having trouble reading the accelerometer on your AltIMU. Can you read other registers on the accelerometer, like the WHO_AM_I register (0x0F)? Can you communicate with the other I2C sensors on the AltIMU? How are you supplying power to the AltIMU? Can you post pictures that clearly show your connections?
