"A0 worked a treat! although I only get a reading of between ~ 1 with tx off and ~57 when tx on, but I guess this is the difference between 5v and 3.3v."

Bill Bonney replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"Try A0 or A1 instead see http://code.google.com/p/ardupilot-mega/wiki/APM_Parameters#Receiver_RSSI_sensing_pin_(_ArduPlane_:RSSI_PIN)"
Alex replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"So I built the above converter and now seem to get an analogue 0~3v. I've set the RSSI_PIN to 8, but only see 0 in the Mission Planner...
Any ideas? "
Alex replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"Did you try this and have any success?"

Matt replied to Marc's discussion Arduplane 2.70 Altitude failure in the group ArduPlane User Group"Not sure if its relevant, but I lost altitude significantly on a flight whilst following the Navigation Tuning instructions.

Matt replied to Shyam Balasubramanian's discussion Triggering a Camera: APM or Arduino"Does the camera triggering work in Arduplane 2.7?
We can't seem to get it to function."
Matt replied to Matt's discussion Circle mode failsafe error in code."Ok, that does make sense,
Considering the chance of failsafe and gps failure, I would say that the chance of wind blowing you off course during a failsafe would be hundreds of times higher than the chance of GPS failure, so it should probably be an…"
Paul Feely replied to Matt's discussion Circle mode failsafe error in code."Matt, On the intended behaviour of CIRCLE you might find this useful from the 2.69 release notes, Paul
'Another significant change in mode behaviour is that CIRCLE mode now holds altitude. This is important because CIRCLE is used in the first…"
Matt replied to David Jones's discussion Compile errors with ArduPlane version 2.70"Thanks,
I was compiling from a different location and needed to email the hex file build.
The answer was:
In the Arduino program: go to Arduino > Preferences and then select Show vervose output during -> compilation.
Finaly, when you are…"

"HI Matt,
Thanks for the report, that does indeed sound like a bug. I'll have a look at it for the next release.
Cheers, Tridge

Matt replied to David Jones's discussion Compile errors with ArduPlane version 2.70"Hi,
I have managed to compile the 2.7 code on OS X, but where do I find the compiled hex file?
Thanks
Matt"
Matt replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"Thanks Bill. I'm pretty sure your original line of code will work, but it surprises me that no one using arduplane has ever needed to use RxRSSI.
I just need to figure out how to compile this.
Cheers
Matt"
Bill Bonney replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"That's rubbish. It means its not assigned a pin in ArduPlane. I'll look at it tomorrow... and work out what you can do. (should be simple)"
Matt replied to Matt's discussion Rx RSSI parameters request in the group ArduPlane User Group"Many thanks, i will give it a shot.
I had located that line in the code actually and wanted to change it:
This is what it looks like in Arduplane 2.7
rssi_analog_source = hal.analogin->channel(ANALOG_INPUT_NONE, 0.25);
can you…"

Just noticed you're from Sydney as well - interesting coincidence.
Did you ever get a reply about using XBees to control your plane? I'm contemplating building my own PCB to tie the various components together, but if the ArduPilot can handle an uplink, that would be much easier.
Have a nice easter,
Kelvin

Connor said… - Hello
I'm trying to find out if it is possible to control a UAV throw xbee from a laptop? I was reading an old post of yours and was wondering if you had found out if it’s possible. Even if direct control is no possible can new GPS coordinates be uploaded to the ardupilot while in flight?
