No Pitch, Roll Euler values - broke IMU?

Posted by Chris Holloway on July 24, 2012 at 8:25pm

I've just noticed a problem with my V3 - the unit is not printing pitch and roll values. This is a recent occurrence, it was working fine a few days ago. I verified the behavior on the demo program.

!!!VER:1.9,AN0:0.00,AN1:0.00,AN2:0.00,AN3:0.00,AN4:0.00,AN5:4096.00,RLL:0.00,PCH:0.00,YAW:-122.79,IMUH:253,MGX:-59,MGY:166,MGZ:365,MGH:-121.79,LAT:327983080,LON: 1158801730,ALT:2852,COG:284,SOG:79,FIX:1,SAT:10,TOW:233223500***

I think it's broken. Anyone have any ideas?

I'm using a MediaTek GPS, for what it's worth.

    Hi, had exactly the same problem after trying to change gyro range to 250DPS. Got scared, tought I fried the gyro...
    Tried lot of things, and code rewrite...
    Then I tried to press the sensor IC a little and I've got it's outputs back.
    Obviously there is a batch with bad solder joints if I'm not the only one with such an issue.

    I'm on remote location for another two weeks, but I'll try to re solder my arduimu in the infra red oven when I get home. I'll post up if it will work out.
