SOLVED Erratic speed and no steering in auto mode

Posted by emile 'butch' alline on July 12, 2014 at 4:52pm

All LEDs solid, all voltages nominal.   Manual and learning modes work fine.  With hundreds of meters to WP, rover goes fwd and rev erratically with no steering in auto mode.

Please have a look at my 52 sec. video showing MP screen.

I have yet to reach my first WP, so any and all help would be appreciated.

      Thanks TCIII,

      param file attached as debug.param

      distance from home & rover to WP 1 is 288M 

      telem enabled, hdop 4, sats 7-8

      compass current heading red line is accurate, gold line is accurate, black line jumps all over, green line bisects red and gold.  compass is calibrated and agrees with two other compasses and other maps.

      When I say learning mode works, I mean that I can control the rover with R/C Tx - i.e. the same as manual.  Throttle and steering are smooth, proportional, and in proper direction.

      Tried alternately reversing both elev and ail in radio calibration and there was no change in auto mode behavior.  Still goes full speed in both fwd and rev with occasional full stops.  

      My Taranis is set up as:

      Tx elevevator stick is APM rover ch.1 output to ESC(throttle) and MP radio calibrate roll graphic.

      Tx aileron stick is APM rover ch.2 output to steering servo and MP radio calibrate throttle graphic.

      Note that I have gone from MP 1.3.5 to 1.3.6 to 1.3.7 in the last few days so the playing field may have changed.

      Also I have blocked up the rover for these tests so that it does not move.  But even if I manually rotate the rover, the compass & heading changes but servo output remains around 1500.

      Thanks again and I'm looking forward to your suggestions.

      DUH! pilot error again.  

      APM output pins reversed, probably related to previous brain fart.

      Will try your suggestions. Thanks for your help.
