I am preparing to take advantage of the MP's antenna tracking ability and I am interested in what peoples experiences are with the two common controllers, Maestro and the Ardupilot legacy board. What are the Pros and Cons for each and why did you choose the board you did?
Also there are a few things that are unclear to me.
1) For those who are using Maestro, where did you get the source code for accepting input from the MP. Links for downloading source code would be appreciated.
2) What is the most recent version of the source code for the Ardutracker code? I have found the link in the wiki to version that reports it has been deprecated but I have found no other version available. That version is listed as ver 1.0, but I have seen posts where people make reference to a version 1.1. Links to downloading the most recent version would be appreciated.
Thanks, that's a bummer. Well, if it's an easy fix and you get around to it, I'd appreciate it. I thought it was clever to design it so that it could go 400°, allows me to fly a little behind myself with worrying about having to swing around. The pan servo is fairly slow so I wanted to avoid that. Takes something like 3-5 seconds to pan around.
in my experiance it doesnt realy matter, as 90 percent of the time the tracker will be at or close to 90 degrees tilt, so spinning around realy has no noticable effect.
One soultion would be to simply use a diversity setup with one directional and on e omni antenna. Since transit time is only really a problem at close range the omni would be well within it's range to provide a strong signal, and when at sufficient distance the speed of the pan is more than sufficient to provide excellent range with a directional antenna. It's a bit more expensive to setup this way but way more reliable.
I've tried to set this up with the Micro Maestro and while I can get the Pololu command center to move the pan/tilt servo's on the tracker. Using the same comm port in the MP nothing happens, I can move the trim sliders and the servo's don't respond.
Comm port and baud are the same settings, but in MP the communications led on the Maestro just does one quick flash and goes back solid anytime I click the connect button.
In the Pololu software it rapidly flickers and of course the servo's work as I move the sliders there. I'm using MP 1.2.35 mav 1.0
Any suggestions that might help? It appears to me that MP isn't establishing comms with the Maestro. I've tried all the baud rates on the drop down menu, none of them do more than that single quick flash when I press connect.
Well I finally got the Micro to respond sorta, had to set up the Maestro in Pololu's Controller to default to the USB port for comms. Now though the pan servo operates like expected, but the tilt servo goes to the pwm limit and stops.
Looking at the settings in Pololu's control software, the tilt servo is going to 2000 pwm pulse width. Using the MP antenna tracker, I can use the trims and where ever I leave them, I can go to Pololu's control software and the pan servo shows the setting from MP but the tilt servo is always at the max of 2000.
I can use the Pololu controller and move the tilt servo, so it isn't the servo or the Maestro. Has anyone gotten the Micro Maestro to work with the antenna tracker? If you have, care to share some settings or things to check?
In Maestro config software I had to set the serial config to USB Dual port.
I've still not gotten it to track with any accuracy.
