Hi Andrew

It looks like my navigation gremlin isn't completely solved. I've posted an update with images and logs at http://diydrones.com/forum/topics/fly-away-saved-at-1-8km-help-with-logs-please

I wonder if you're able to see anything else obviously wrong?

Thanks

Tridge, can I bother you to look over 5 log files to see if you can spot the crash and possibly what happened? I was flying my Skywalker with the exact same setup as always and have had many successful flights until yesterday. Two back to back and a totaled plane now. In FBWA it would go into a steady downward pitch. It was unresponsive to any of my input. I tried manual and RTL with no response. I had I think 5 logs on the APM after the flight and Ive looked through them, but Im not sure what Im looking at. The plane on the last crash stayed dangling in a tree for about 4 hours while I tried to get it down. Anyways, I would greatly appreciate your input. Email me if you wouldnt mind taking a look at the logs.

Thank you sir.

Jamie

Hi Andrew, Ive just finished putting in a section on how to flash your PX4FMU board with the latest developer ArduCopter PX4 code from your firmware object repository.

It's pretty ugly and includes quite a bit of stuff for setting up  development environment as well.

And sadly at the end after flashing the new code to the PX4FMU it still won't establish a MavLink connection with Mission Planner although I am pretty sure the board is properly flashed.

I am giving you the link to my Wiki debacle here: https://code.google.com/p/arducopter/wiki/PX4_First

I would greatly appreciate any feedback you could give.

I actually produced this primarily to get feedback from you as I did not want to waste any more of your time than necessary with incomplete back and forths.

If you can point me in the right direction(s) I would greatly appreciate it and will be happy to modify the Wiki page appropriately.

I figure that if we can get this simplest FMU only one to be "acceptable" the rest should fall into place fairly easily.

Thank You very much for your assistance with this.

Hi Andrew - 

I am new to ArduPlane development and having trouble getting it to build with Arduino.  

I would greatly appreciate any direction you can provide on what I am doing wrong.

This is what I have done:

I have downloaded Arduino 1.0.4, 1.0.3 and 1.5.2... I get the exact same set of errors whenever I tried to do a Verify / Compile of ArduPlane with any version of Arduino.  

There has to be something very basic here that I am missing.

I went here to get the latest Arduino development environment http://arduino.cc/en/Main/Software
There I downloaded Arduino 1.5.2
I extracted that to c:\Programming\Arduino
Then I was able to open Arduino and build their example programs without any errors.
I followed these instructions for getting set up for doing development:  http://arduino.cc/en/Guide/Windows
No problems with building the Blink test example.
I set up the Arduino Sketchfolder here:  C:\Users\Sid\Documents\Arduino
I set this in Arduino's preferences
I then went to this page and followed the instructions for setting up ArduPlane development https://code.google.com/p/ardupilot-mega/wiki/Code
I went here and downloaded the latest ArduPlane software - ArduPlane 2.7.1  https://code.google.com/p/ardupilot-mega/downloads/detail?name=ArduPlane-2.71.zip&can=2&q=
I unzipped it to my desktop.
I then copied them to the Arduino Sketchbook folder as shown on Chris' web page (only using Sid instead of Chris).
Inline image 2
I then opened Arduino 1.5.2 and did a Verify / Compile and got the following error messages:
ArduPlane:239: error: new declaration 'uint8_t digitalRead(uint8_t)'
C:\Programming\arduino-1.5.2\hardware\arduino\avr\cores\arduino/Arduino.h:102: error: ambiguates old declaration 'int digitalRead(uint8_t)'
ArduPlane:1288: error: expected constructor, destructor, or type conversion before 'int'
ArduPlane.pde: In function 'int SKETCH_MAIN(int, char* const*)':
ArduPlane:1288: error: 'OK' was not declared in this scope
compat.pde: In function 'uint8_t digitalRead(uint8_t)':
compat:33: error: new declaration 'uint8_t digitalRead(uint8_t)'
C:\Programming\arduino-1.5.2\hardware\arduino\avr\cores\arduino/Arduino.h:102: error: ambiguates old declaration 'int digitalRead(uint8_t)'
I am at a loss as to what I am doing wrong here and I hate asking for help.  Any direction would be really appreciated.  I will be ecstatic when I am able to get ArduPlane to build and can start doing real development with it.
Thanks again.
Sid

Hi Sid,

Have a look at http://firmware.diydrones.com/ under Tools, in the Arduino directory. That is the Arduino version you need.

Also see http://dev.ardupilot.com/ for more developer information.

Cheers, Tridge

Hey Andrew! I'm flying an X8 with APM 2.5. I have quite struggled trying to tune the bird to the right PID settings. Lately I have been using the X5 Param file posted in the Common config website.
I noticed the X8 in your display picture, can you help me by sending me the parameter file you've been using?
My AUW is 4kgs. Any changes or suggestions to keep it safe and stable? I've taken care of the wings. Also when I was using the Arduplane 2.72, my plane would snake around while navigating. Is there anything I would've missed out?
Please help.
Thanks!

Hi Tridge,

Would it be feasible to code something to use the laser altimeter currently discussed on top content blog (link below). It's the first low cost and accurate one I've seen and could be used for both arducopter and arduplane, would be really good for autoland for both and avoidance, not to mention the what to do with it if put on a servo. Possible? If so, who would be best to ask to do this? Thanks.

Ryan

Dear Andrew, I recently got back into RC modelling after 50 years (64 now) there have been some significant advances in both radio and airframes since the old OS Pixie days and rubber escapements.  I bought a Bixler 1 now a 2 which I wanted to fit one of the Hobbyking Crius AIO FC's to. The Multiwii and megapirate AIO FC with a Atmega 2560 MCU.  Which firmware would you advise to upload, preferably something which will make the setup as much plug and play as possible. Are you aware of any periodic gatherings down here in Melbourne for like minded RC flyers?  I thank you in advance BR Paul.

Hey Tridge,

I went out earlier this week and flew a mission with the University's plane to test out the GeoSearch program. After completing the mission, I put it into FBWA to bring it down for a landing. about 75 ft off the ground, it went into an straight down nose dive. This is the second time its happened, but this one was unrecoverable. Needless to say the crash totaled the plane. I was wondering if you could look through the logs to see if it is possibly the same issue as the bug that was fixed in 2.76.  I was running 2.76 firmware. I looked through the logs and you can see where the APM received the command to pull out of the dive, but the servos never responded to the command.  Anyways, I was thinking it is either the bug or an interference problem from a cell phone tower about a mile away. My professor wants to make sure either way before we put more money into the project. Ive attached the log files and would greatly appreciate any feedback.
