Hi, can anyone confirm that I2C is working on the Arduino Due part? I have 3 I2C devices, a MPU6050, MPU9150 and a Chronodot V2.1 and all work on my Arduino Uno without any problems (without external pullups). But I can't get them to work on my Udoo Quard! :? I also used pullup resistors (2k2, 4k8, 10k). I really appreciate any help!
