It's solved. There was a accuracy problem because my algorithm was skipping some lines from DMP code while it was writting it (specifically the two last lines from "dmpUpdates[MPU6050_DMP_UPDATES_SIZE]" in "MPU6050_6Axis_MotionApps20.h"). Anyway, after I get the code that working fine, I found another accuracy problem but this time in Arduino library. This problem happends because the hexadecimal code from Invensense isn't updated. In a few days, I will try to update the code because the last version is very quickly and very accurate if we compare it with the other version.

Hello! Firstly, I would like to thank Jeff Rowberg and everyone who has contributed and made ​​this library possible, it has been of great help to me in my purpose to understand the DMP. So, my case is: I'm migrating DMP for MPU6050 library to 8051 (specifically SiliconLabs C8051) but I don't get the expected accuracy. I need to use in my project roll axis measure, so I did several test and these are my results for the same sensor: While for Arduino Roll conduct begins being destabilized (picture 1). After 10 seconds the measure is stabilized and it gets a good accuracy (picture 2), with a tolerance of 0.06 degrees. In my case, Roll conduct begins stabilized apparently but the accuracy is similar to that obtained by the raw values​​ (picture 3). I thought it might be a offsets problem, but I calibrated my sensor and the results are similars (although better). Any idea about fix this problem? Thanks in advance! Greetings from Spain. Andrea
