I'm having trouble getting i2c communications working with LSM9DS0 iNEMO inertial module. I've wired it up, but it isn't responding to who_am_i read request. I've wired SDO to 1, so am using your default i2c address 0x3A, but I'm getting no slave ACK signals. Out of desperation wondering if I had the address wrong I pinged every i2c address, and still found no response. I've tried 100 kHz and 400 kHz, same result. I've also wired different i2c sensors, and they work fine, so I know the rest of my board works. Are there any tricks getting i2c to work?
