Altitude Hold Help?

Posted by Steven on March 24, 2011 at 9:51am

Hi, I cant seem to get altitude hold to work. When I turn it on the motors just stop. I tried turning it on and the quad just fell out of the sky so I quickly turned it off and the motors came back on.

 

I'm using ArduPiratesNG (rev. 527) and I have the pressure sensor selected for altitude hold:

#define UseBMP    // Use pressure sensor for altitude hold (default) ?
//#define IsSONAR    // or are we using a Sonar for altitude hold?

 

Does anyone have an idea of what I may be doing wrong?

    Use the examples in the library and post your reading for the Pressure sensor.

    The test file is in: ...\libraries\APM_BMP085\examples\APM_BMP085_test\APM_BMP085_test.pde

     

    Upload it to the board and enter in Serial Monitor.

     

    You could also try the Alt-Hold in the Configurator, on the bench with motors andl Lipo disconnected (!).

    Use your transmitter to arm the motors and chked what happens to the motor bars when you engage alt-hold.

     

    Hope this helps,

    Emile
