No Angle Outputs in the ADIS16480

merlin
on Mar 19, 2013

I can not read any Euler's angles or velocity (DELTVEL)! I mannaged to read the PROD_ID,temperature, pressure and gyro reading well, however for Euler's angles and velocity I'm only getting zeros.

When I the the EVAL-ADIS (evaluation program) the angles are obtained well both when using the 4D visualizing function and even when saving the data on the excel sheet. However for the velocity, the readings makes no sens.

The following is few of the data I'm getting while maneuvering slowly the ADIS16489:(sorry couldn't find a way to upload an attachment)

X_DELTVEL_OUT Y_DELTVEL_OUT Z_DELTVEL_OUT ROLL _C23_OUT PITCH_C31_OUT YAW_C32_OUT

Can I get some help please?

    Hello Merlin,

    Since this is a separate application, I hope you don't mind me creating a new discussion for this.  We have two other reported cases like this and have decided to offer replacements, while we continue to investigate the root cause. Can you send me a private message with your email, so we can start the return/replacement process. We do expect to post an update for the root cause, once we are 100% of what has happened. Regardless of the follow-up activity, we do apologize for the inconvenience and will work to address this quickly.

    Best,

    I have to apologize because I jumped to the wrong conclusion. You appear to have Euler Angle outputs in the evaluation software. In the evaluation software, are you able to read the EKF_CNFG register value? That might be helpful.

    Yes I can. However i am unable to obtain X,Y and Z_DELTANG_OUT not even using the evaluation software. Can you advice me how to attach a file and I'll attach some readings for you with what I'm implying.

    Thanks,

    Merlin

    Hello Merlin,

    Yes, that is why I asked for the EKF_CNFG contents. To attach a file, click on "Advanced Editor," which is located in the upper right hand of the Editor.  Then scroll down, below the editor to see the "Browse" button on the left side, which allows you to select a file to attach to the post. Please see the pics below for graphic reference. I hope that helps.

    When you first click, Reply, look here for the Advanced Editor option:

    I am attaching the Configuration EKF_CNFG settings as a picture.

    Also please fins the first attachment with a set of data including x_accl_out, y_accl_out, z_accl out, x_deltang_out, y_deltang_out, z_deltang_out, x_deltvel_out, y_deltvel_out, z_deltvel_out and Eulers angles.

    Please note the ADIS velocity values are not making sens as in my opinion the rest are working fine.

    Also when I use SPI communication, I can read the normal data well, such as temperature, production ID, gyro readings etc,  but I am unable to obtain Euler's angles nor the velocity readings.

    What I can notice is the the Euler's angles are not in relation to Magnatic North but the the start-up position each time I switch the 3D view on.

    Regards,

    Merlin
