Hello, I made something to my APM2.5, that killed a part of it.
I wanted to try the PPM Sumreceiver port an made a mistake. I used the picture here http://code.google.com/p/arducopter/wiki/PPMsumRC but I had my APM2.5 turned 90degrees clockwise and so I connected the 3 Wire lead to the first Pins on the SPI block (that next to the USB connector) and shortened the 2nd and 3rd inner Pin on the SPI socket. There was no smoke and no spark, nothing.
Now I can connect the board to the Missonplanner, I can change firmware, I can read out the mavlink Parameters and I can see the compass and GPS Test in the Terminal giving correct data.
When I see at the Flight Date Window, I cannot see any Sensordata from the board.
I meassured the fuses and the diods. The diode near the SPI block, has 246 in one direction and 1500 in the other, when it is on the board, but it has 1 in the other direction when it is soldered out, so the diode seems to be o.k.
Could anyone imagine what could have been happened to my APM2.5?
Is there any chance to get that solved?
Kind ragrads

Hi,
Wait....You say everything works, except that the horizon in Flight Data doens't move when moving the board?
Even if you bust an input port for the RC, it should not really affect the sensors. They will work without any working RC connection.
I suspect that you might have moved the board while powering it up (and the LEDs were flashing)? This could cause the calibration to fail, and (maybe!) cause the whole INS to return no data.
Maybe repeat the experiment with the board sitting quite still until you are connected.
You can also do the ins test in the command prompt (terminal). It is menu "test", subitem "ins" . If you see all 6 sensors responding as they should to movement, hardware is probably O K.

You say you have 'killed' a part of the board. If you go back to no PPMSum config without the jumper between the signal pins 2 & 3, does it resolve the issue?
