OSD Low Airspeed Stall Warning

One of the nice things about the old Night Ghost MinimOSD fork was that you could set stall warning based on a min airspeed to flash in the center of your OSD - these were done by the Minim firmware I understand. After having had a few near misses recently with stalls, I was looking to see if I could figure out a better OSD Stall Warning.

A LUA generated GCS message is not ideal but I can see how I could do this. Can LUA scripts interact with the OSD? Does anyone have any good ideas as to how to effect such an OSD warning?

we do have a warning blink with user-settable thresholds for RSSI, GPS stas / hdop, voltage and terrain. why not just add one for aspd?

not sure right now if scripting has OSD access, but what you might want to try is to script a mavlink message if aspd drops below a given threshold. this can be displayed using the osd message panel.

A blinking ASPD would be good. I will look at scripting a mavlink message.

I am surprised that I am the first person to ask about this!

Thanks for your reply.
