ArduCopter-3.2 beta testing

Warning #1: PX4/Pixhawk users upgrading from AC3.1.5 (or earlier) may need to re-do their compass and accelerometer calibration because AC3.2 also uses the backup compass and accels.  Pre-arm checks have been added to ensure this has been done.

Warning #2: on the APM2.x the logs must be downloaded using MAVlink instead of the terminal.

AC3.2-rc14 is now available for BetaTesters through the mission planner’s Beta Firmwares link.  The full release notes can be found in ReleaseNotes.txt and changes from -rc13 can be seen below.

     Feel free to raise issues found during testing on this discussion or in the new support section in the APM Forum.

     It’s a big release with “the onion” restructure and a bunch of new features (including these 57 closed items) so we need to re-test almost everything including all flight modes, all mission commands and all the new features.  Marco and I will be maintaining (and adding to) this testing list.  Issues reported will first be checked by Jonathan, Marco and I and then confirmed bugs/issues will be put on the github issues list (and then hopefully fixed).

     Thanks especially to the beta testers who put their copters at risk testing each release.  Enjoy!

Changes from 3.2-rc13
1) Safety Features:
     a) fail to arm if second gyro calibration fails (can be disabled with ARMING_CHECK)
2) Bug fixes:
    a) DCM-check to require one continuous second of bad heading before triggering LAND
    b) I2C bug that could lead to Pixhawk freezing up if I2C bus is noisy
    c) reset DCM and EKF gyro bias estimates after gyro calibration (DCM heading could drift after takeoff due to sudden change in gyro values)
    d) use primary GPS for LED status (instead of always using first GPS)

            • I hate this "don't ruin it for the rest of us" approach. It's excluding and borderline irrational. People do stupid things with cars everyday and no one has been prevented from driving.

              And for the "newbies" out there. You don't have to land in stabilize, just switch to stabilize as soon as you land in loiter or other auto mode, and pull the trottle down before disarming.

              LAND > THROTTLE DOWN > STABILIZE > DISARM. Zero issues like that.

            • Yes you are right Chim,

              but just to let you know. I´m starting with flying since 35 Years, I´m starting with Autonomous flying since 5 Years. I´m flying also commercial.

              But i´m not able to programming  C++ or others.

              Still I do fully auto Takeoffs and Landing, because this has to improve and tested all the time. This is the future!

              Takeoff and Landing were nearly already possible with the Arm-O-Kopter Firmware from Hans!

          • T3

            Right, it is pretty mature!

            I ordered a lidar lite and hope it will arrive soon.

            • where do you ordered it? I want to have it too!:-)

  • Help!!

    I have a job to do tomorrow and I cannot get the pixhawk to trigger a 3v micro relay .. I get a momentary 2.8v/3.0v signal out of Aux 5 pin (54 I think its set in MP) when i flick the radio switch ..BUT, when I connect it to my relay no voltage is seen with my test meter .. I suspect the Aux pin which supply's the 3v signal does no have enough amps to activate the coil on the relay ..hence the voltage is killed..! this relay is used to trigger my NEX 3 via the multi port .. It work s fine if i apply 3v direct to the relay coil ??

    Regards

    • The solution is well documented here: http://diydrones.com/forum/topics/using-aux-pins-as-relays-for-chdk...

      • Hi Phill I am not using Chdk  ..  I only want to operate a 3v relay. with the 3v signal from pixhawk.

        • @Reuben,

          The Pixhawk is not capable of directly sourcing the current required to operate a relay. The solution in the thread I referenced shows a two transistor electronic switch designed by Marco that will operate your relay (or a Canon camera) along with the configuration options you will need. It works with 3.2 or 3.1.x.

          • Thanks Phill .. I will build the circuit and just use a 3v supply rather than a 5v one .. the question is.. are the components in the design  compatible with a 3v supply .. or would I have to change the values of the resistors ?
