What would cause the panning direction to be reversed? Is there a setting to change that?

BTW, if it matters, I changed out the pan servo because I thought the other one was damaged but found out it was just because the pan tilt kit wasn't balanced well so it was refusing to move. It's the same size but different brand. Do servos have different default directions of travel?

It sounds like the PWM vs rotation direction varies between different manufacturers.  I never really thought about this issue when using servos in non UAV helis and airplanes since you can always reverse the servo direction on the radio. The Ardustation software has to be modified to reverse the direction of the pan and I think it will be as simple as adding a "180.0 - servooutput" in the code but I need to look at it when I get more time this evening.

Here is the change to the code to reverse the pan servo direction

The code is in antenna.pde

// Offset for servo limit
Bearing_Home = Bearing_Home + offset;
if (Bearing_Home > 180.0)
Bearing_Home = Bearing_Home - 180.0;
else
{
if (Bearing_Home <0.0)
Bearing_Home = Bearing_Home + 180.0;
}
Pan.write(Bearing_Home); //180-(Bearing_Home/2.0));

Change the last line to:

Pan.Write(180.0-Bearing_Home); // reversed pan servo rotation

This should reverse the direction.

Thanks Heino! First I'm going to test the original servo because I think it's ok. It just wasn't panning because I had too big of a battery on the pan tilt kit.

"Pan.Write(180.0-Bearing_Home); // reversed pan servo rotation"

Heino,

i had to change the pan servo rotation, but with the big W in "Write" it gave a mistace. It must be written with a small "w", now it works!

Joachim,

I'm glad that the servo reversing is working for you and you're up and running. Version 2.0.15 is coming very soon - I'm testing it now with Mavlink 1.0.

Is 2.0.15 comming soon with Mav 1.0 support. I am going to update my stuff for the Sparkfun event and wanted to update my Ardustation as well but it needs to suport Mav. 1.0

Just curious.

Hi Jack,

I'll release it tonight - I've had it ready and tested with the previous GIT trunk but was waiting for the 2.6 beta release which is happening right now. I'll retest with the Arducopter since there were Mavlink 1.0 changes over the weekend.

Heino:

 

Thanks I figured you were waiting for the trunk to stabalize and 2.6 release. I am loading 2.6 now and will be doing some tresting after that I will look forword to testing your update.
