Is there any information on hacking/modding an fpv feed to give custom information in the display?
For instance, let’s say I added a thermometer or some other instrument to a drone and I wanted an onscreen view of the reading on the drone - which system would be the simplest to get into to add something like that in the goggle display?
And I’ll take analogue and digital answers for this!
I actually purchased a device that sits in between the feed and the output (i.e. cam / VTX), which you can code to do this. Was going to use it for custom projects where don’t have an FC which has one built in. I don’t see why you couldn’t add this inline with what the BF FC outputs and put it before VTX, but you’d also need to code for it, so would need another device taking the readings from the thermometer and putting onto this OSD. I don’t think Betaflight can add custom elements to OSD, and can it even take a pin input for reading temp?
