I am using ADXRS290 gyro and i will be happy if someone can help me with the next issues:
regarding to drift compensation , i read many articles about this topic and i am still very confused:
for drift caused by temperature - i am planing to sample the gyro output (4000 khz for 30 sec) to estimate the offset for each temperature , is this method will give me satisfying results ?
figure 5 shows curves of drift vs temperature and they are very inconsistent ,(what does the N=16 number means? ).
i dont really understand how can it be possible to compensate that behavior, every curve behaves very different , is that caused by bias stability?
i also tried to use the high pass filter - it gave very good results for the offset correction but the dynamic behavior was very bad for our application . i saw the next explanation in the datasheet :
"The high-pass filter can be set to the fast settling option, allowed to converge to zero offset, and then set to any other high-pass filter option while maintaining near zero offset"
what is fast settling option? does that mean to dynamically turn on/off the HPF.?
thank you very much
