Consistent spikes
Posted: Tue Jul 07, 2015 2:19 am
Hello everyone,
I've been trying to perform static calibration on the AutoQuad 6 board for the past week or two. First time around, I ran firmware aqv6.7.r224.b1400-rev1 and got solid results. After that, I put the DIMU on, running aqv7.1.1852-hwv6.1-dimu1.1 and try to get similar data. However, one of my gyro axis looks to be out of wack, and the mag data doesn't look too nice either. I would love to hear your suggestions about what I did wrong. Maybe the DIMU is defective? Anyone with a working DIMU would like to sell me one? Viacopter and Flyduino is out of stock again.
I am not leaning toward any reason concerning the thaw environment because I got good data for the 1st run with the analog IMU. I've also tried with and without the sandwich bag method, no difference. I've checked all solder joints and connections. I am thinking it may be because of condensation but I've tried the method of leaving it open in freezer, close sandwich bag and lid when ready, take out and thaw. Am I doing something wrong?

As you can see below, one axis of the gyro looks messed up. The spikes are almost exact through 4 trials.
