Real time linux on my project

[Luis]

Hi everyone,

I am working on a project (for a NGO on Costa Rica) on which I will be
developing a fully autonomous flying aerial photography platform. I will
be using a powerful stealth computer on board which will be running
(hopefully) a CONFIG_PREEMPT_RT modified Ubuntu for all the actions
taking place (Control, sampling, communications, etc). I'm really new to
real time. I will be sharing all the code and all the development will
be open source so if anyone has recommendations, questions, things I
should read, I'm open to hear from you. I will be controlling a small
buy yet powerful gas helicopter and using a USB-DUX for the DAQ needs.

Hope to hear from many of you soon,

Luis Quiros R
Engineer

What is a stealth computer?

I'll give a few hints to the *coding*, not the rt-patch series itself:

For a general guide to the coding, I'd say have a look at 
http://rt.wiki.kernel.org/index.php/HOWTO:_Build_an_RT-application

Also, look into 
- mutex/semaphores
- threads
- message queues
have a look at https://computing.llnl.gov/tutorials/pthreads/ 

If your system becomes very large (and you have very formal requirements) 
perhaps you should look into using Ada?

Good luck with the project - share some photos/videos of the aircraft in 
action! :-)

Hi Luis,
  I am an engineer at Novell and work on the PREEMPT_RT patches.  I am
coincidentally also into RC helicopters as a hobby, so your project sounds
interesting to me.  I look forward to hearing about your progress.

Good luck!
