We've just released ArduPlane 2.33 for your flying pleasure!
This release adds three new features over the previous release:
The new MAVLink stream handling means that when you ask for a telemetry stream you can now ask for any stream rate that is a multiple of 20ms period. Previously if you asked for 5 Hz for a stream then you got it at 3.3Hz, as we only supported 1, 3.3, 10 and 50 Hz streams. The new stream rate code is much more flexible.
The main motivation behind the new stream rate code is the ability to get the most out of the new 3DR radios. The new radios send information on their buffer state to APM, and the APM code can now adjust the telemetry stream rates to ensure that the internals buffer in the radio doesn't overflow. That allows you to run the serial link to the radio at a much higher baud rate than the radio link is using. So you can adjust the air data rate to improve range without having to reconfigure APM and the radio for a different serial rate.
The end result is that if you have a 3DR radio you no longer need to carefully adjust your MAVLink stream rates to fit in the radio bandwidth. Just ask for a high number and the APM will adjust the timing to whatever fits.
Thanks for the logs, they are very useful. I think they will lead to code changes for the next release.
I will write a little program to work out what sort of transformation we need on your accelerometer vectors to make them give a constant gravity vector length. Once I've done that I'll post an update.
Thanks for your help!
Let me ask you one more thing. Would you recommend going back to 2.28 to fly, or i can use 2.33 with this error?
A have to fly it.....
Do you have any information on the new release? :)
I've pushed the fix you need to the master repository. I've also done quite a few test flights and it seems good.
Do you know how to download from git and build yourself?
Well, i have uloaded 2.28 succesfully before.
Can you give me a link?
I think i have found it.
What would you recommend? How should i test it? :)
Have you followed the basics?
Using relax patch Arduino?
Loaded the libraries?
Anytime you get messages like that, you are missing librarys (files with code).
Follow these directions exactly:
Managed to upload it. :)
Now i see 90° when it is 90° !
But pitch newer shows -90°.
-86° is the max
This is pretty close.
It will fly tomorrow!
I hope everything will go just as i expect it! :)
Thank you Andrew!
Hi Andrew, Today i did some flying.
Made 4 flights. roughly 10 minutes each. Used modes: manual, stabilize, rtl. Everything did go well.
I will take off a few more times tomorrow also. Will try auto mode.
Thank you again,
I did the same placeing my APM1 on the table. It was as still as possible.
Newbie question. I see all the discussions for the APM and the new radios,
At this time I am not comfortable with using the new radios on a UAS I may eventually sell as a product because of the uncertainty regarding certification.
My current setup is using 900mhz Xbees and I am just putting it all together.
My question is will the Various AMP2, Mission Planner and Arduplane softwares CONTINUE to support the Xbees? Or do I need to stick to a certain revision that will work correctly. How do I tell the softwares what to talk to?
Dwgsparky..... somewhere up the learning curve!
