Hi all, I'm trying to use the mpu6050 as a shock sensor (ie if a shock is > 2g's log the force and timestamp it). Here's the twist, I managed to get the MOT_INT working, but I eventhough i see changes in force required ro triggger an interrupt ( setting MOT_THR byte) I can't map it reliably to an actual G value. Each accelerometer output is on 16bits (signed) but the threshold is set on 8bits (signed) (which means you can only set the interrupt as 1/128th of the actual resolution ?). Also, once the interrupt is triggered, how am I supposed to find the "triggering value" in the fifo stack ? If you have any idea, please share
