hi all

im using ADIS16448 with pic32. im having a problem and i wish if you can help me wihh.

 

im reading out my ADIS, im receiving correct data for the identification register. but im facing problem in understanding the

accelerometer/gyro/mag/baro and temp data. im reading it as raw data and im not sure how to perform calibration on.

 

pages 19 and 20 in the datasheet talks about calibration my ADIS, and i think i need to do some initialization first to get correct data. im not sure how to do it. i've read the bias and scale correction registers and they are not equal to zero. should i set it all to zero or what ?

 

can u PLZ help me?

the attached files are the datasheet and the data output from ADIS (stationary and aligned horizontally)
