Right now I have been working on another application with the MMA8451Q. I want to get tilt with resolution up to 0.02 degree using only one axis. This accelerometer counts up to 4096 when 1g. But the problem is the maximum speed I could get is about 800 samples per second and make an average of those samples I only could use 10 or 11 of stables bits (bits not affected by noise). It is not good.
Thanks in advance for any advice,
