Hello! I 'm developing a motion detection application using MMA8453Q and I2C for communication between the microcontroller and the accelerometer. Occasionally, like once every five or ten seconds, there 's a spike in the data. For example, the z-axis acceleration is at around 1.0g and suddenly it drops to almost 0.0g and goes back to 1.0g. All of that happens in 3 samples, at 800Hz.
Is this a "normal" situation or there's something I'm missing? One of my colleagues thinks it's a problem with the I2C, but I doubt it.
