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).

          I was a bit confused reading your previous post but now everything is clear regarding version. 

          Regarding accel calibration, I will do this step at the end, doing first RC, compass, etc, and see what will happen.

    I have pushed a fix for the parameter corruption problem to ArduPilot master. Randy is preparing a new beta release now that will have the fix.

    Hi All,

    I have reproduced the parameter corruption issue on my Pixracer. I can confirm the problem does happen with master, not just the beta releases.

    I have also reproduced the problem with px4 master, so the problem is not ArduPilot specific (I have given instructions on how to reproduce on px4 master in the PX4/Hardware gitter channel).

    I am working on narrowing down the issue. I have shown that the issue only happens with the ms5611 baro driver is started, which points the finger at a likely SPI bus corruption problem (as the ms5611 and FRAM storage are on the same SPI bus on Pixracer, a key difference from other boards).

    These types of issues can be quite tricky to track down, but I will see what I can do.

    Cheers, Tridge

    I ordered one for my Sub250 gram Micro, I will post when its complete and feed back on how it works on a very small copter

      Speaking of light weight copters, I'd suggest they ship the PixRacer w/out the servo headers soldered in place. It's much easier to solder than to de-solder.

    My parameters are not saving. 

    latest mission planner.  Not the beta, because the beta crashes before it even opens. 

    Do I  need to use the beta MP?

    Copter 3.3.4-rc2 is shown as being on the copter, up at the top of mission planner. 

    I calibrate, save. refresh params.  They're all there.  Unplug the pixracer and plug it back in.  All settings gone back to the default/initial 3.3.4-rc2 settings. 

    This is all while connected and powered via USB

      Also, after rebooting and comparing params, a lot of the params rather than being reset to what they were bfore, are actually displaying as "NaN".
