I added the DX8VB.dll that apparently isn't a part of the DirectX install anymore (which is something I need to consider for future developments!)

Here it is, the thread.

Ok, v1.1.8 should have the yaw smoothed out. Do you think I should have a scaling factor for the accelerometers? That way it might be more useful if your output is only small movements. I'll also look into the naming of the fields.

Comment by Krzysztof Bosak on March 10, 2010 at 11:02am

I don't think the different scalings are necessary.
This is what I have typed on vimeo:
No way you can jump off scale if your G rating of accelerometers is 1.5, 3, 6 or 11G...
In practice in autonomous flight G scales are 1..2G in Z, -1..1 in the remaining axis. With manual flying you get -2..4G on Z and -1.5..1.5 on X and Y.
All values typical for agile, overpowered EasyStar but also other high-wingers/trainers.

Therefore I would suggests something close to EasyStar ranges mentioned.
Above 4G home-made toy aircrafts start to bend and decompose anyway.

Ehh, something went wrong during reinstall (sounding like Sonic something plugins)
and cannot access the app anymore, even it Hyperterm can see things.
+++RLL:0.2,PCH:-0.5,YAW:59.2,AN0:0.0,AN1:0.0,AN2:-0.0,AN3:2.9,AN4:4.2,AN5:102.6,***
Probably I have changed something but don't remember what.

Got it. The terminal window IS NOT showing the RECEIVED strings, but PARSED strings.
big difference when debugging. So the protocol needs !!!.
Now the funny part. Ardu GS fast message (roll/pitch) needs +++, while Ardu GS slow message (lat/lon) needs !!!.
On the other hand IMU test fast message needs !!! for roll/pitch
What a mess.

very nice DODY

Well, throw in some binary to and that's what in dealing with...

Comment by Paul Mather on March 10, 2010 at 1:10pm

I didn't make the protocol...

Krzy, we're cleaning up the protocols across the board for Mega. Thanks for the constructive feedback.
