MultiWii

Hi all,

So I have a GPS and a SR04 sonar module attached to my gps-i2c-nav board. It's running r62 of the code. Sonar module is ticking away, and is producing sensible waveforms on my scope. GPS data is coming through. I have tweaked the Multiwii V2.2 code on my Crius V1 board to read the sonar data via the gps-i2c-nav board. Mods to the code were found here https://github.com/luggi/multiwii-firmw ... 06ab7db57f

Question is how do I tell in MultiWiiConf if the sonar is working or not ?

Also with respect to flying the thing how does the sonar input integrate with the baro sensors height estimation ?

Thanks.
Cam.

nada
it is not implemented yet.

Only good for turning on landing lights then ?

EDIT: I'll answer my own question: The centimetre value shows up in debug[2] in MultiWiiConf, and sure enough from looking at the code all it does with sonarAlt is switch landing lights on or off.

sonar attached to an i2cps board is not implemented at all it multiwii yet.

Yup I got that, it also appears any other type of sonar does very little also. Landing lights from best I can tell. No problem here, just wanted to check I wasn't missing something.

If I could make dreams come true, this is what I would like to work on, that being Obstacle Avoidance, not so much auto-landing. Given the current media climate and fear mongering, it would be nice to have a copter that knows how to avoid objects.

Saw that vids a few years ago, think it was responsible for kicking me off with multicopters. Very good.
