Gyro Calibration

It increases by 1 for every 5-6 print outs of the gyro angle, so if it has to reach 900 (90 deg with setting at tenths of a degree), it will take a long time to increment to that value. Isnt the gyro angle supposed change faster?

I am using the frc_gyro code version 0.4 from your website, without any changes other than gyro sample ratte at 1600Hz and samples per update at 64 (Ive tried other values to but with same results). I have not changed anything with user_routines.

Hope this makes it clearer,

Thanks.

Yes, it should change much faster than that. When you assembled the gyro, did you connect a jumper wire between the AVCC (pin 1) and PDD pins (pin 13)? If not, connect the two pins together and it should start working.
