MPU-6050 accelerometer bias

By hatemtaha , 9 May 2015

Hello, everyone. I hope this isn't a FAQ. I tried doing a search for "accelerometer bias" but it wouldn't show me any results because both words are too common. :?
My one and only MPU-6050 reads 0.89g on its z axis when it's one way up and -1.12g the other way up (direct register reads, ±2g range). That's some serious bias! Is this typical or do I just have a defective MPU?
