Missing Yaw transfer
Hey, I just wanted to use your code for my esp8266, and I realised after looking at it that there is not Yaw Transfer ongoing. As far as I know, if you pitch your device and then yaw it the pitch will be not correct anymore. You can see why in this video clip. I´ve already added a time mark. https://youtu.be/4BoIE8YQwM8?t=606
Maybe I just was blind and didn´t see it and you´ve already added it.
Maybe if have the time I can change it myself
Yes, and unfortunately it also looks like the yaw angle gets wrong after moving the sensor around for a few seconds in each axis. When moving back to start orientation pitch and roll are about 0 again but yaw is about 45 degrees off. Might it be the same reason? Any updates on this @Pascal-Lohscheidt ?
Thanks!
Unfortunately, I didn't have much time in the last month's so I had to pause the project. But I'm sure it's probably just a few lines of code. The video explains it pretty good.

So you think the reason for wrong yaw angle over time is the missing yaw transfer, too?
Well, I can't prove it as I have no idea of your set-up. But I can imagine that is a valid reason. Another reason could be your loop frequency. If it's low it could cause a lot of measure gaps.
I used the default get angle example which gives me this issue/ So seems to be a general problem caused by library. I will try to build an own function that generates angle by taking raw accelerometer and gyro values into account. Let's see if it works. After implementing this I hopefully know what is missing in tockn library
Yeah, I did this before and switched to that library because of issues after switching from Arduino Mega to ESP
I think I'll still use the library to get raw values but but not the angles. I'll let you know.
This library do not gives the Euler angle, it only integrates the angular velocity, which isn't the same. I'll change to other library...
