Comment on Flying the Libelle DLG on a slope by Linus Molteno

That looks awesome! I’m definitely going to have a go at that really soon. I didn’t even know it was possible to slope soar there, I’ll definitely try there, and thanks for the tips.

Nice custom power upgrade!

In reply to Scott.

That ability has not been added yet, but yeah that would be an interesting idea for the Blackbox. It doesn’t seem like that would be a useful feature for the Configurator since the 3D model would just be window-dressing at that point (wouldn’t reveal the actual attitude estimate of the FC so doesn’t reveal anything about potential flight problems).

The skipping of the IMU happens here:

https://github.com/cleanflight/cleanflight/blob/master/src/main/flight/imu.c#L304

imuCalculateEstimatedAttitude() is never called when an accelerometer sensor is not present.

Has anyone added something so we can get accSmooth in the Blackbox but not run the IMU attitude code? Couldn’t we also use the Blackbox viewer’s IMU code in the Configurator so it still worked without the FC’s IMU? When looking at the code it appears it still runs but all acc inputs are 0. Is that correct or am I missing where the code is skipped?

In reply to Colby. Which ESCs are you using? I think some of them don't like sub-1000 looptimes.

In reply to nick. I disabled the accelerator and lowered my looptime....now my quad falls out of the sky :(

In reply to Zap Andersson.

There is a bunch of time involved in just simple multiplies, divides and additions as well, so speeding up the trig functions isn’t everything. But yes, there is speedup to be had from improving the trig. Check out this PR for a faster trig approximation solution: https://github.com/cleanflight/cleanflight/pull/1092

In reply to ingmar. Yes, it does currently avoid reading the accelerometer I2C registers when the acc is disabled, so there will be a speedup from that.
