Re: [Paparazzi-devel] Lisa/M: Pitching Reversed and Rolling is Pitching

[Gareth Roberts]

Hi Chris,

If you have an FTDI cable you should be able to connect the AP straight to  
your GCS without needing to setup the xbees.  This will be invaluable in  
debugging - it could be your IMU orientation is incorrect, in which case  
you'll pick it up straight from the GCS.  If the IMU is correct, your  
servos must be reversed somewhere.
Also check your transmitter for reverses - remove all reverses on the tx  
and then verify the transmitter xml is correct.

I'd seriously recommend getting messages hooked up, you're going to be  
debugging in the dark otherwise.

Cheers,
--G
