Are you connecting via MAVlink?

Thanks for the reply Chris.

I am using the connect button on the top right corner of APM Mission Planner. The APM1+IMU Shield hardware is connected to my PC through a USB cable. I am accessing the APM1 hardware over the FTDI COM Port option at a speed of 115200 bps. The connection is successful. I could configure my RC Controls limits over it.

I do not have a XBee transmitter / receiver connected.

To add to my reply Chris ... I guess the protocol is over USB COM Port is MAVLink? I am using it.

For testing I installed ArduCopter-2.5.4 on the same hardware with same setup. The Attitude indication on Artificial horizon works well. The Mission Planner Artificial Horizon in this case displays "Disarmed".

When I install ArduPlane the Artifical Horizon displays "Armed" and does not move. The raw sensor reading as I mentioned is always 0.

ArduPlane is what I want to work with,

Thanks,

Found the same problem listed on another thread ... but no solution

http://diydrones.com/forum/topics/hud-stuck-on-arduplane-apm1

Briefly:

MissionPlanner-1.1.87 with APM1 + ArduPlane-2.34 = HUD (Attitude Indicator) Not Ok

MissionPlanner-1.1.87 with APM1 + ArduCopter-2.5.4 = HUD Ok

Wondering if there is a difference between ArduCopter and ArduPlane in the way the data from the APM1 is routed over the USB COM port to the Mission Planner.

Any ideas ... anyone?

Thanks,

Mahesh M.

Problem listed above SOLVED!!! .

For APM1 with 2560 hardware and ArduPlane the SLIDE SWITCH needs to be in "fly" position (away from the edge, toward the GPS connector). Once set the attitudes are indicated on the Mission Planner Artificial Horizon as you move the hardware.
