Help getting MPU6050 working with Arduino Due

Hardware Arduino Due
2

I2C is not broken on the Due. I've ran it for days at a time without a failure. Have you tried the i2cscanner sketch to see if you are using the correct address?

edit: The I2C address could be 0x68 or 0x69, depending on the state of AD0. If that pin is floating, it could be changing.

And this. I found some devices require a short delay here.

                Wire.endTransmission();
                delayMicroseconds(100); // add this delay
                Wire.beginTransmission(devAddr);

Wait. That was wrong. There is no beginTransmission for a requestFrom.

            Wire.beginTransmission(devAddr);
            Wire.write(regAddr);
            Wire.endTransmission();
            delayMicroseconds(100);
            Wire.requestFrom(devAddr, (uint8_t)min(length - k, BUFFER_LENGTH));
