Arducopter 2.0.44

Posted by Jason Short on September 23, 2011 at 3:00pm

Lots of small tweaks and performance improvements. Here's how testing AP went in the Park:

3689425580?profile=original

 

3689425548?profile=original

 

 

If you compile with Arduino, you can now set CH7 to trigger some cool things like RTL, or In-Flight leveling. 

Check the GIT tree for details on the changes. Most are just nerdy code optimizations.

 

This release feels very close, if not the last beta. Thanks for all the testing,

 

Jason

    Jumpa: Git instructions are in the ArduPlane manual. But we really recommend you do not fly code pulled straight from the repository. It's a development environment and at any given moment may be unstable. We push code out to the public (zip or hex) after it's been tested, but the trunk is usually in flux.

    Hi Juampa,

    You can merge your existing repository, or at last resort delete your current repository including the dir name and clone again.

    Please can anyone post a step by step about how to update from repository?

    I'm very confused with GIT, I can do a full checkout but not able to see and get updates later.

    I've already read tutorials with no luck.

    Thanks!!

    Chris: So can I reload the 2.0.44 code through the 1.0.75 mission planner and the chnages will be picked up or do I need to do it manually throught the cli downloading the 2.0.44 zip from the downloads section? I will be sure to keep logs today by the way. Also is ALT HOLD still disabled due to issues and needs to be manually turned on in config.h per an earlier comment I saw?

    My initial test with v43 and v44 were the same, i flipped number of times and even if I would take off it would act like a seesaw violently shaking my quad. I had to cut down almost half on my stab_pitch_p and stab_roll_p but try the version where Jason set the rate_pitch/roll_i is set to zero. There is a big difference.

    Jani: I will just confirm I loaded 2.0.44 after a full reset. e.g erased the EEPROM, went through full calibration and level checks.

    Greg: 2.0.44 was updated today to resolve that. Please reload and try again. Takeoffs should be smoother.

    Jani: I Just tested 2.0.44 last night. Same issue as you Something is not quite right. Takeoff is very tricky, I need to look into it more today. For me the quad is dipping suddenly i.e not stable around all four points on the axis. Once airborne ii is ok, but super sensitive (minimal osolation). The quad I tested is one I built from jDrones 880kv motors and 12x4.5 props. This frame was fine on the 2.0.37 code I have been running for some time. So could be me getting used to the newer code. I do agree with you take offs on 2.0.44 one shoukd use caution.

    I can confirm the kmz problem that Helldesk has. I have been tuning my quad pids for a few hours today and I get the same 5kByte log files with no gps positions after kmz creation.
    I do wanna say a big thanx to all involved in the hard work with trying to get the 2.0 release past beta state...you are doing very well!

    No that's not it, although the absolute altitude instead of relative to ground issue is another thing that needs fixing in the kml creation process. I just re-downloaded a clean 1.0.75 and tried re-creating a kml. No dice. Even re-creating kml files from older logs does not work.3692275149?profile=original When opened, Google Earth pans to the general area of the planet but nothing can be seen at ground level. Nothing about the log files seems strange (and the last time I cleared everything was today before I flew 2.0.44). I regularly clear my logs after flights.
