      • Hi, thanks for the info. I got a teensy from the local electronics shop today and it works like a charm. I think the teensy solution is simpler too. Just one board instead of two.

        • Hello, is your teensy working with the 3.3 firmware in pixhawk ?

          • Hi Ed

            It works - not perfectly - but works good enough with 3.3-rc3 for me, using wolkstein code.

  • Hi, sorry if this has already been mentioned - I couldn't find anything.

    FrSky makes a number of sensors that attach to their SmartPort in a daisy-chain manner. Can anyone tell me if attaching their Vario or Voltage sensor, for instance, would cause problems with the Teensy 3.1?

    Thank you.

    • I have used the voltage sensor with the teensy at the same time, but i asked one of the devs to add an option to disable the teensy from sending the voltage cells data. This is the code i use (just comment the line in FrSkySPort.h corresponding to the sensor you want to use):

      • Thanks, this points me in the right direction.

  • Hiya, has anyone got any of the variants working with 3.3 firmware yet?  As soon as I upgrade all the telemetry on the taranis goes blank..

    • Sorry turns out I had ripped one of the wires out of the teensy when I was rebuilding my quad.  Resoldered and it works fine now.  Well not perfect, rc1 seemed to work perfectly but since rc2 or rc3 it's not 100% - some weird false mode changes announced using the wolkstein variant although I've made various other changes to the parameters so might be related to that.  But good enough - I use it primarily for the voltage display.  

      Hopefully when 3.3 is released final then someone will update their variant, possibly in line with opentx 2.1.

    • The 3.3 thread mentions having to set SERIAL2_PROTOCOL to 3, though that's not been sufficient for me.  I am testing with 3.3rc3.  The light on the Teensy is just giving a slow heartbeat, not the fast flashing I am accustomed to.  I would be interested to know if that fixes it for you. 

      • Setting SERIAL2_PROTOCOL to 3 just changes to FRSKY telem output, the type used directly to a d4r-ii or using an inverter with the pixhawk, but since you are using the teensy to convert mavlink, you don't want that, so it's not the fix if 3.3 is broken.
