IMU shield/ oilpan gyro problem

I am using configurator v1.2.1 and software 1.31 for my arducopter.
The gyros do not show any movement when I twist and turn the quad.
The acell pitch and roll move all over but the gyros stay centered and do not move.
I ran APM_ADC test using the serial port and the numbers show the gyros are not moving.
I did re-sets and initialized EEPROM but still no go.
I moved to v1.33 and still the gyros do not move.
They have never moved and now I am stuck.
Do you know if I can send the board in for testing or repair?
Will I have to purchase another board?
Is there a way to test a new board to see that the gyros and accel's work?
Thank you for any help.

Channel 2 and 3 show no movement and they should be gyro X and Gyro Y
here are the lionks to where I posted the results

On Ardupilot Mega Hardware:
Channel 1 : Gyro Z
Channel 2 : Gyro X
Channel 3 : Gyro Y
Channel 4 : Acc X
Channel 5 : Acc Y
Channel 6 : Acc Z
Channel 7 : Differential pressure sensor

  • Just another question on this. If all is programmed correctly and you only connect the APM and IMU. Does the artificial horizon also move?
    Gyros, acelland pitch indicators move.

    John,

    I have a different channel arrangement for the sensors on the IMU Mega and they seem to work for me:

    Serial.print(APM_ADC.Ch(4)); //X-Acel
    Serial.print(",");
    Serial.print(APM_ADC.Ch(5)); //Y-Acel
    Serial.print(",");
    Serial.print(APM_ADC.Ch(6)); //Z-Acel
    Serial.print(",");
    Serial.print(APM_ADC.Ch(2)); //X-Gyro
    Serial.print(",");
    Serial.print(APM_ADC.Ch(1)); //Y-Gyro
    Serial.print(",");
    Serial.print(APM_ADC.Ch(0)); //Z-Gyro
    Serial.print(",");
    Serial.print(APM_ADC.Ch(3)); //Temp
    Serial.print(",");
    Serial.print(APM_ADC.Ch(7)); //Aux

    I say this because the original channel designators were for a version of the IMU Mega that was earlier than the Foxtrap which was the current version. I could be wrong, but this channel arrangement works for me and IMU Mega users on the Aeroquad Forum.

  • Contact Jordi or the store. I had the same problem with my z gyro. I sent it back and he fixed it. Just got it back today. Looks like just your xy gyro isnt connected right on the board. I saw the youtube video from rcgroups
