The first prototype that will be used by someone other than me :)
I've pretty much settled on hardware configuration. There's still some space for optimization (like size for example) but that shouldn't affect the codebase too much.
ENGO 2 indeed pretty good for this purpose. Although there was no SDK for ESP32, I was able to write some basic implementation using the documentation available.
Still there's a lot of work to be done. In the sort term:
* Complete "Competition mode' - UI tweaks, navigation, score computation
* Implement data input - home DZ coordinates, altitude offset, target coordinates for competition, etc.
* Stability overhaul
In the long run it'd be good to have some smartphone app to manage all the settings, as well as create custom screen layouts, but there's still long road ahead
