  • Ok I got it. The Ev. Board came configured with a 10 bits resolution and +-2g acc range. If the acceleration values are in the FFFF range it means it is working on the negative direction (For example in the X axis: FF = - & FF = 255 => -255). So I created a Matlab script that handles this, if the value starts with FF just consider the second two letters and add multiply by -1, if it doesn’t start with FF just consider the whole value, then multiply this values by (4)/210 to get it in gravity values (g’s), where 4 = +-2g and 210 is the resolution of the data. Good luck!

  • Why am I getting FFFF (65536) values? Isn´t it supposed to be just 10-13 bits? Thanks
