Arducopter 2.0.48/49

Posted by Jason Short on October 11, 2011 at 10:32pm

There is a preview on GIT right now. I flew a version of this

The PWM output has been set to 400hz (to counter the low pass filter in most Turnigy PWMs)

The DCM's Roll and Pitch gains were lowered to .03 (recommendation of Hein Hollander)

Mavlink has gotten a re-work for performance and memory savings.

Added a scaling factor to camera Roll And Pitch CAM_P_G, CAM_R_G in the params list.

Fixed some bad PID values for Alt hold that were giving folks trouble.

Exiting a WP for another is faster and more controlled now.

Added user hooks for those who want to execute their own code inline.

Increased loiter speed to center when the copter is flown > 400cm (now 800cm).

Loiter in action.

Tested 2.049 indoor today, made some PID tweaks, now copter is very stable, no oscillations at all. It must be the best firmware of all.

Here is a short video:

Just a question to all of you: I was using 2.0.46 before and then switched to 2.0.49, nothing else changed. In 46 I was able to see logs in the MissionPlanner log window, but with 49 it never shows any logs available. If I do 'dump 0', it will print a bunch of data that I can copy over to a textfile and display, but never does it show actual log files to download in the menu.

I'm not even sure it has to do with the swap to 49, I'm just trying to figure out what to do about it. Thanks!

When I use .49 just one ESC gets initialized. When I loaded .47 all of them worked properly. Any idea what might cause this?

Furthermore, keep up the good work! :)

I tried to enable current logging and couldn't. I typed "enable current" and nothing happened. However, I could enable/disable other types of logging.

I think Mr. Anderson is right ;) it must be something with flash and ios5 because I restarted the ipad1 after closing all apps and the problem is still there. Also waited for page to fully load. Never had this before upgrade to 5.

I did try 2.0.49 today and i did not see yet the strange gyro drifts i had with 2.0.46.

I have only 24 minutes of fly with 2.0.49, but it seems ok. I need to tune PIDs now and fly this a few hours to be sure.

I still have the flip tendancy if i try to take off slowly because of the 0.001 roll / pitch I parameter. Perhaps we could do something to null the I parameter before and during take off.

The simpler to avoid this is to null the roll /pitch I parameter.

Sorry to post this here. I'm waiting for new motors to arrive to give 49 a try but wanted to say that following this blog on an ad is almost impossible. It just wants to constantly bounce to the near top of the page to show the hobbyking ad. It seems to have started a few weeks ago or maybe when ios5 came out.

Mmm, without any hardware change I'm seeing a steady yaw drift clockwise, from .47 to .49 ?

But, THANKS Jason, this code just gets better and better !

I'm test Loiter and Auto mode. This is auto mode Pretty good don't worry. but loiter it have some oscillate move to circle about 3-5 m.

setting waypoint

Auto mode Airline

Jason,

I find problem's about download in APM Planner. When I will download logs it not have log in list.

But , When I will type logs in CLI or Terminal. it's have log in list.
