GPS & IMU

Posted by John Klier on May 28, 2010 at 7:20pm
If I am using the IMU is it necessary to plug the Ublox GPS into that board or can it plug into the shield? If I plug it into the IMU the IMU will get a solid blue but the shield and Ardupilot will continue to blink blue. If I plug it into the shield the shield will get solid blue but there is no blue light on the IMU. One picture in the IMU manual shows the GPS plugged into the IMU board but the shield blinking blue has me concerned.

    Mike,

    I just uploaded the modified system.pde with my AP 2.6 code and now get solid blue on IMU, shield and AP. Tomorrow I'm hoping to be able to make the connections you mentioned to my FTDI cable so I can monitor communication to the shield.

    I'll be waiting anxiously to hear what Chris finds.

    You're help is greatly appreciated. Next time I'm on that side of the pond I may need to buy you a pint.

    The GPS should be plugged into the IMU. Have you set the ArduPilot config file to tell it that you're using the IMU?

    //0-3
    #define GPS_PROTOCOL 3 // 0 = NMEA, 1=SIRF, 2=uBlox, 3 = ArduIMU, 5 = Simulated GPS mode (Debug)

    You need to have the GPS plugged into the arduIMU if your using the arduIMU. Is there GPS data coming through to the ground station?
