Hi,I recently had a bad crash and the 3.3V voltage regulator on the Oilpan that is located close to the I2C port was damaged. I replaced it with an absolutely identical chip (got the correct part…Continue

Hi,I suffered a pretty bad crash last week and since then I can't get my compass to work anymore. However, I am not sure if it's the compass that's actually broken or maybe my IMU board.The compass…Continue

Hi,I'm just starting out with my Arducopter project and still have a lot to learn about the code, so pardon me if this question has been addressed before.I understand that the autopilot main loop…Continue

Hi Jan,
If you have some questions about DCM, post them on my comment wall. That way it won't clutter up the forum, but if anyone else is interested in the answers, they will be able to see them. I think that is what the comment wall is for.
Best regards,
Bill
Hi Jan,
I am not familiar with the ArduCopter implementation. Jason Short would probably be the best one to ask about the ArduCopter strategy for accounting for acceleration in roll-pitch gyro drift compensation.
You have to account for the effect of acceleration on the gravity reference vector used in the roll-pitch gyro drift compensation calculations when the average value of the acceleration in the body frame of reference is not zero over a significant period of time.
Best regards,
Bill
Hi Jan,
You asked me about sampling gyros and accelerometers under low sampling rates. Unless you are doing "dead reckoning" from the accelerometers, (I assume that you are not) get as many gyro samples as you can. Your suggestion of getting one accelerometer vector and as many gyro vectors as you can in each communication pass of the I2C seems to be the best approach.
Best regards,
Bill Premerlani
