Baro Altimeter

Hello Again...

 

I have been trying to setup my altitude hold function and am having a hard time. No mater what my settings, the quad just slowly climbs or sometimes slowly descends. I have put the P value to 100 and it still does it! I have manipulated I values, IMAX, Throttle Rate values, it ALWAYS responds the same. I downloaded my logs and as far as I can tell, the baro alt is always showing zero, even when I climbed a solid 50 feet. I have tried removing my foam cover from the pressure sensor, it is open to the air, sun etc and it still does it. Its like the sensor is broken. Any ideas? I am sure its something simple, it almost always is. I have attached my most recent log file.

    I compiled via Arduino and rolled back to an older firmware, just to check, no luck. I guess there is a mechanical problem? I have inspected the pressure sensor under a loupe, it looks fine, it does not appear loose, I press on it and it does not change anything. I am out of ideas.

    Did you compile this with Arduino? I'll bet you've got the HIL version running.
