Ardupilot 2.5 Release Candidate

Posted by Jason Short on January 31, 2010 at 9:30pm
I was finally able to test 2.5 over the weekend and added a few tweaks to the code.
Here's what I hope is the final release.

As the new Manual gets formatted, you can view it at: http://code.google.com/p/ardupilot/wiki/ArduPilot25
Until the content is finally moved over the 2.4 manual is still a great resource.

Ardupilot_25_RC2.zip

Bonus - If you look check out the Waypoint_writer_25.pde file in the test suite, you can upload relative waypoints. This isn't supported in the config tool yet.

UPDATE -
A lot of people were having trouble with the GPS code and LEDs. I reworked the GPS parsers today to iron out some things. They were nothing that would interfere with flight, but I highly recommend using this new version. I've also added the ability to scale down your plane's roll based on airspeed. This should help planes that turn faster when they go slower. We may tweak this a bit in the future, so I'm looking for feedback on it. Note you can always turn it off in your header file with this line:
//6-4
#define AIRSPEED_TURN_P 1
see the header file for more instructions

    The throttle failsafe looks for a low PWM value. To test, you could go through the initial setup with the throttle half on. Then after you remove the RemoveBeforeFly jumper, lower the throttle until you see it switch modes.
    You should see the word failsafe and the mode set to RTL.

    Of course, don't connect the engine while you do this ;)

    After setting the failsafe, I change back the throttle trim & endpoint back to normal setting. Test OFF the radio and nothing happen.

    Saiful,
    That looks pretty good. Do you get the failsafe message in the Serial Window when you switch off the radio?

    @Doug Weibel - I use JR PCM 9XII with corona rx. That's mean for the fail safe I have to lower the throttle channel trim & endpoint, the flight mode stick in MANUAL position? Is that right?
    Here my radio test in MANUAL mode

    Radio tx OFF

    Hi Joel,
    ArduIMU will be supported in 2.5.1. Doug is busy with that right now and we'll have that ready soon.

    Jay,
    The blue lock LED will always be on when the GPS reports it has a good signal. If the GPS is disconnected or has a blocked antenna, it will turn off.

    Jason:
    After completing the field setup should the GPS_lock go off?
    I'm using a em406, everything else seems normal and the gps test works fine.

    I'm just askin, is this fully compatible with arduIMU?

    Hi Nippy,
    Yes, the yellow stat LED isn't going to happen. With the limited IO of Ardupilot, I had to sacrifice it. If I could, the Remove Before Fly pins would be next. If anyone knows a way to remove those let me know.
    Jason
