5DOF IMU ROLL Wrong way Pitch OK !!!

[Ebi]

Hi everyone,

Just finished assambling my Mega board with WMP Original and 5DOF IMU from Sparkfun.

I have one problem the ROLL Axis goes the wrong way on the IMU. The PITCH axis is right.

If I roll to the right in stabilized mode the left motor will increase speed

What should I change in the code ????

Thank you for you Help,

Ok, don't know much about programming Arduino but found the answer.

Alex souldn't you change this on the next v1.7 too ? My 5DOF IMU is mounted like on the aeroquad shield.

changed ligne 910 on v1.6

FROM

accADC[ROLL] = accADC[ROLL] - accZero[ROLL] ;

TO

accADC[ROLL] = - (accADC[ROLL] - accZero[ROLL]) ;

How to connect 5DOF IMU on you Arduino Board

X (5DOF IMU) is connected to A2 (on Arduino)
Y (5DOF IMU) is connected to A1 (on Arduino)
Z (5DOF IMU) is connected to A3 (on Arduino)

Now everything perfect will go for a test flight
