  Thx Grant for the orientation parameters.

  Is there an issue with using pass through pwm on RC9-RC10-etc in ardurover ? I tried today pass thru but servo would not move (has a BEV on servo rail). I then tried the car!era gimbal functions, also not moving servos. I tried another BEC, still no servo reaction.

  Hi Grant. Yes I have. The Piksi hasn't been very useful until now as it hasn't been stable. With the new release V16 the Pixhawk doesnt manage to read the data correctly.
  I will try to contact Niels

  Thanks

  Hi Anders.  I haven't setup my Piksi's yet.  Have you read these pages?  They should help.  Otherwise try contact Niels Joubert who wrote the driver.

  Changing UART mode in Piksi dont help, Status is 1 and never increase although the Piksi sees many satellites.

  After upgrading Piksi to version 16 I cannot get the PixHawk to communicate with it. I have tried it as GPS1 and GPS2 with the same result. Baud 115 and tried protocol 1 and 5 without success.
  What protocol should Piksi use to communicate with Pixhawk?

  Thanks Tom.

  Hi Hugues.  There are 2 orientation parameters.  One for the pixhawk board and one for the external compass.  Have a look at these pages:

  Goodluck! Grant.

  @Hugues,

  You might have to orient the GPS/Compass the same way that the Pixhawk module is oriented on the chassis.

  This sounds like a problem that might require assistance from Grant Morphett.

  Pixhawk and GPS+Compass module orientation question :

  -Pixhawk is turned 90 degrees clockwise relative to the front of vehicule

  -The external compass+GPS is facing the front of the vehicle

  I tried "Rotation_none", then "rotation yaw 90", also "rotation_yaw 270" with no success in having the front of the vehicule facing North (checked by looking at mission planner's HUD). I made a reboot and compass calib dance at each change. No joy.

  Any ideas what I'm doing wrong ? (or known issue in rover code ?)

  @Hugues,

  I have bought all of my Traxxas Slash/E-Maxx roller chassis and hardware off of eBay from sellers with 99 -100% ratings.
