Could that be the cause of this?

Re: Ground too feature rich? (Flow deck)

Here's the video:

See how weird the horizontal position control behaves when it gets over the ArUco markers? It may have something to do with the altitude measurements, which are taken from the ceiling with the Multiranger Deck.

Ground too feature rich? (Flow deck)

Is there such a thing as a too feature rich ground for the flow deck? I've printed several ArUco markers (similar to QR codes) on an A4 paper and the CrazyFlie seems to have a hard time flying over it. I'm uploading a video, I'll post it soon.

Has anyone had similar issues?

Re: Switching altitude measurement from downward ranger to upward

Recently I got back to this. One problem we still have is that flow measurements rely on distance to ground. I believe it takes absolute altitude in based on how it behaves, though it would work much better using zranger data, I believe. Haven't found where in the code the magic happens yet. Can you...

Re: Switching altitude measurement from downward ranger to upward

The code isn't decent. I essentially took every shortcut I could find. :p

That's why I won't post it.

But it seems to work just fine!

Re: Working with VS Code

Just found this and this.

At the very end of the second link:
VS can certainly be used as an IDE, but hooking it up to the ARM toolchain for building might not be possible. Investigation needed.

Working with VS Code

Is anyone using VS Code to work with Bitcraze stuff? I'm fairly new to all of this so pointers from someone who has successfully done it would be appreciated. I've been using the virtual machine for that stuff, but I use VS Code for pretty much everything else these days. Would be great if I could m...

Switching altitude measurement from downward ranger to upward

Greetings, in the continued attempt to fly the CF over non-flat grounds, I had a new idea. This occurred to me after acquiring a multiranger deck. In the vast majority of places we fly our CFs, the ceiling is much flatter and bump-free than our floors. My idea is to use the upward ranger on the mult...
