PixRacer with Ardupilot

Posted by Randy on February 9, 2016 at 4:47pm

This is a discussion to focus the feedback and support of ardupilot on the PixRacer board from AUAV.co.

We believe that all teething problems encountered are now resolved and so we recommend people load Copter-3.3.4 which is available for all multicopters through the Mission Planner's (and other GCS's) Install Firmware screens. Note that because regular Pixhawks are still on Copter-3.3.3 the install icon may show Copter-3.3.3 but rest assured, Copter-3.3.4 will be installed (you can check the version by looking at the very top of the Mission Planner).

      Corrrect Port. My R6303SB works properly.
      
      But my Futaba Equipment is stored in the shelf since I have Taranis.

I see what is going on now - evidently copter picks these up from the telemetry modem as it is plugged in. I had been moving between Telem1 and Telem2 trying to determine why Telem1 was reliable and Telem2 was not. FYI - these modems work perfectly on my PixFalcon - no problems there.

  My OSD on telem2 recently stopped working...
  It worked a few months ago.. Then after a few months of testing APM and not really flying FPV, I tried it again for the first time in months, w/ no changes to the copter other than code...
  And I cannot get telem2 to work! I moved my OSD to telem1, and it's ok there.
  
  I don't know if it's a bug, or something physical broke on my pixracer... As I said, I got it working for me on telem1, but if others are having trouble w/ telem2 and OSD's please post.
  
  I did check the port on a scope, and it is always 3.3v flat line.. No signal present, regardless of the sr2 settings and baud settings, etc in the code.

    for some reason telem2 on all pixhawks doesn't work reliably with minimOSD I hope someone will find the reason eventually. telem2 works fine with telemetry radios and frsky telemetry though. I think it is because minimOSD can take a whooping 500mah if powered by 5v.

      Oh interesting, thanks..
      That might explain why on some flights, my OSD went blank, too... I think it was on flights where I push the throttle, so might have been causing a bit of a brown out for the OSD.

    Same issue here. Telem2 takes a fit and won't work. Moving to Telem1 seems to solve the problem. A real shame, as Telem2 is the easier port to access for me.

      What a pitty I'm building mine and telem 2 is the easier port for me too, When I finish I post results, thank's to alert.

        Radiomodem on Telem 2 is working at the moment for me; first plug.

        Thanks! I think my port is dead, in my case.. Lot of crashes between the last time I used it a few months ago, and now... My guess is some wires got crossed and I got 5 or 12v on the serial tx line.
        
        There's not a separate serial enable disable type setting in the code is there? Only SR values and baud are the only settings related to the telemetry ports, right?

        SERIAL1_PROTOCOL?
