Unexplained fly away logs here but don't quite know how to interpret.

We were doing a demo for some water resources groups here in the SF north Bay area along the delta showing salinity gradients at specific GPS locations. The protocol was to take off in auto mode and…Continue

Long distance milestone for multirotors?

I have seen a few users with "100 km" badges, and I believe these were all achieved with fixed wing platforms. (Right?)I am wondering... what are the longest distances people have been able to cover…Continue

Search is working for me

Comment by Jay Johnson on June 25, 2013 at 3:19pm

Anyone else getting "no results" when using the Search function on the discussion forum?

Sounds great Stephen. Thank you.

Wayne - you can find the pre-built hexes at http://firmware.diydrones.com/  You will want the "daily builds" of the appropriate branch (copter, plane, etc)

Note that these builds are compiled and uploaded daily based on the current Git repository so you will have to make sure that use are using the latest codebase when compiling.

OK, that sounds better. Can I download the standard firmware file from somewhere to compare with the one I compiled to ensure they match?

Comment by Stephen Dade on June 22, 2013 at 9:28pm

Wayne - The warnings are expected (and normal) with the APM code. The output file is expected to be put in a temp file - that's how the makefile is programmed.

If you're using the Arduino environment, simply select the mega2560 board and correct com port, then press "verify" and then press "upload". Arduino will take care of the details.

The makefile is only used directly if you're using Linux or Cygwin (on Windows).

Arduino will compile and download from the project directory. The 'verify', which is a compile, happens in the temp. I never did try having arduino install it...
Comment by Wayne Morris on June 22, 2013 at 6:39pm

The make file is just a configuration. I read instructions to run it.

To compile, I am selecting the sketch and clicking compile.

Thanks for the input.

So the output file is:

C:\Users\Wayne\AppData\Local\Temp\build7487716384992828737.tmp\ArduCopter.cpp.elf C:\Users\Wayne\AppData\Local\Temp\build7487716384992828737.tmp\ArduCopter.cpp.hex

I have done other Ardunio projects but the output was in the target directory.
