In firmware download / features.txt, what does the "!" mean?

ArduCopter Copter 4.4
1

I’m looking at the features.txt file - trying to figure if I’d still need to create a custom firmware for a Kakute F7 to get OSD on Walksnail working, or, if all the Walksnail OSD features are included by default.

Anyway, I’m wondering what the exclamation point means in the “features.txt” file - does that mean those features are NOT in the firmware?

Thanks…

“!” often means “not”. Check if you have any winch or rpm params if not then features marked with “!” are disabled.

Kakute F7 features

Thanks Dave.

So to me, it looks like OSD capability is NOT in the stock firmware. Would you be so kind as to check that link and verify?

And if the OSD is not included, that’s a darn shame as I’m 99.9% sure there’s plenty of room in the 1MB of ram to include OSD (partly because when I create a custom firmware, there IS room) - just seems like a popular item that would be near the top of “include” lists.

Also, could you verify that the “!” does indeed mean that a particular feature is NOT included?

Thanks very much.

Thanks very much Lupus - yeah makes sense, I’d just like verification so I know for sure.

Hi Bill- I have a Kakute F7 Mini on a 4" and OSD is available. But, I’m not using OSD/FPV on this craft and I don’t know anything about Walksnail.

Note-I do see that some OSD features are limited out but basic functionality is there. There are also some MSP features not supported which might have something to do with Walksnail not working. But admittedly I’m not very knowledgeable about these protocols.

Dave, HDZero/DJI/Walksnail OSD’s all need MSP activated (analog OSD works fine without MSP) - they work by sending telemetry down to the goggles, and then the goggles themselves create the OSD.

As opposed to analog OSD where the OSD items are added on the airframe between the flight controller and the VTX (integrated on the flight controller with betaflight-type flight controllers as you know).

But I’m only 95% sure of that.

Thanks…
