Hi All, I have an mpu-6050 the when sitting flat on the bench reads, X=-236, Y=-212, and Z=14996, when I turn the sensor upside down, X=112, Y=-660, Z=-18988. Why is Z so far negative when its upside down, shouldn't be near zero? I'm using Jeffs example code. Also page 30 of the register map data sheet states the accelerometer output measurement is a 2's complement value. How do I convert to raw ADC values, and can anyone explain how the mpu-6050 calculates this 2's complement output? cheers mb

Hi All I'm very new to the world of accelerometers gyro's etc, and I've recently purchased a MPU-6050, which I promptly dropped from a height of approximately 2 feet or so, onto my wooded desk top right out of the packaging. This poor thing bounced around a fair bit before coming to a stop. The data sheet states it can handle 10000 G’s, but this value doesn’t mean anything to me. Does anyone know how many G’s my device would have experienced in this unfortunate adventure? One more thing, the data sheet also states the accelerometer data is returned in 16 bits two’s complement form. To ask a question to what might seem like an obvious answer, is it correct that, to get back the raw data I would have to subtract one first, and then invert the whole 16 bits? OR have I missed something? cheers, and thanks.
