Hi,

i  am  a new  in this  hobby )  and  i  cant  understand  how  calculate  a  gyro a/d  output.

i  am  working  with  UDB4.

gyro parameters :  

Vin= 3.3 volt

sensetivity = 2.0  mv/degree/s

a/d  resolution=  12  bit.

i  calculate  the  output  of  A/D  and  think  that  i get  a mistake.

what is the  right  calculation ?

thanks.

Hi Alex,

I suggest you repost your question to the UAVDevBoard discussion group.

Part of the answer to your question is that the software for the UDB4 sets up the A/D to return samples in left justified mode, so you have to treat the A/D data as 16 bit, not 12 bit.

Best regards,

Bill Premerlani

Thanks  Bill,

if i  use  a UDB4 board,  and i  want  to  use  the  matrixpilot 3_2_1   code.

with  which  number  i  need to  divide  in  order  to  get  the  counts  in  rad/s  ? (  i suppose  that  i  need  to  divide  by  5632/4.95 ,  is it right ? )

 how  did you  get  the  5632 ,  4.95  number ?

 

Best  regards,

Alex.
