Yes all the previous plots re[resent the same motion. I took another sample using _low and used 'scaled data' option, please find it attached, the plot looks good. By reading only '_low' I also managed to read DELVEL in the 3 directions. However, I'm still unable to read angles and velocities using SPI. I will try to troubleshoot the problem by readings _LOW only.
So what is the reason that I con not read both _LOW and _OUT at the same time and combine the readings please?
