BMP085 Barometer

[NorcoT]

Hi all, i';ve just built my 250 quad with a CC3D controller, when rummaging through my old box of goodies I found my old BMP085 barometer chip, I used this in earlier arduino based FC I built with MultiWii.

Anyhow I was wondering if anyone could tell me if the BMP085 is compatible with the CC3D and Openpilot as a barometer extension for altitude hold? I think there are more accurate barometers out there but I thought I would toy with the ideas as I already have this one.

Thanks,
Tony

In short, it can';t be done.

The longer answer is that the connectivity is on the board (I2C) but you';d have to write your own firmware for the the CC3D.  As it stands memory and CPU are pretty much maxed out so you';d have to get rid of something else to make the baro and compass code fit.

Not sure if the Cleanflight would be able to assist you in the regard.  Perhaps worth a look.

Alright, thanks for the short answer. Sounds about right I guess, when I was experimenting with multiwii in the past I had same issue, memory was maxed when I put barometer code on it.

Don';t think I';ll bother pursuing it if that';s the case then, I have a 450 with Naza for flying about with gps and alt hold, the cc3d is in my 250 which I don';t need the bells and whistles for. Was just curious.
