Parachute setting on Pixhawk with Mission Planner

Posted by Pierre Pomiers on December 9, 2014 at 8:40am

Dear Diydrones members,

Recently, I decided to install a parachute on my drone (an hexacopter running a Pixhawk with latest APMcopter 3.2 as firmware).

I refered to the Ardupilot related page (http://copter.ardupilot.com/wiki/parachute/#Connecting-to-the-Pixhawk) and followed the basic instructions (how to connect the servo, and so on).

Things begin to be weird at the Mission Planner tuning step... When I go to "CONFIG/TUNING -> Full Parameter List" here is a screenshot of what I get :

3691167009?profile=originalThis is really different of what is mentionned in the Ardupilot page : CHUTE_xxx both "Options" and "Desc" fields are empty (???) and either RC9_FUNCTION, CH7_OPT and CH8_OPT Options stop before proposing "27:parachute" (???).

This is the same when I go to "CONFIG/TUNING -> Extended Tuning" : the "Ch7 Opt" drop-down menu does not propose any "Parachute xxx" item (???).

I really have difficulties to understand why there is such a gap between the official ArduCopter page and what I got.

If any of you managed to tune setup parachute, your help would be kindly welcome.

Cheers,

Pierre.

    Bonjour Pierre & Benoît 

    The parachute is fully functional in copter 3.2 and the instructions in the wiki are correct.

    The problem is that for some reason your parameters options are not updating correctly from our main server.  They should look like:


    3701892480?profile=originalJust like in the wiki

    Go to the main flight data screen, select CTRL-F, and you will see this screen

    Select Param Gen to re-download them.

    If for some reason they still do not show up, you can set the parameters and set the values from the full parameter list, like they are described in the wiki.

      Dear Craig,

      Thanks a lot: we tested what you recommended us to do yesterday evening and everything was successful.

      Now we have to test the parachute release in real situation, ie. flying 30m high and shutting down motors (which is a bit stressing :-).

      Best regards,

      Pierre.

      Dear Craig,

      Thanks a lot for your reply. I will check this as soon as I get back to the office.

      I will keep you informed about the result (that will be positive I am sure).

      Thanks again.

      Cheers,

      Pierre.
