The folder is called linux_code because it mainly deals with code that uses the queue system, which only works under GNU/Linux for a variety of reasons, some fundamental (futexes) and some because nobody bothers to fix them.
The layout is designed with multiple linux boxes in mind.
-The one that talks to the cRIO etc is called the prime. We have multiple explanations for that name:
- It is the primary controller.
- PRIME/Primary Robot Intelligent Management Entity
- Represents Optimus Prime, one of the good transformers who battle the bad ones that 254 names robots after.
- It is easy to type and doesn't conflict with anything else common for tab-completion.
- It's not hardware-specific.
+The code for the linux box that talks the cRIO etc is in ../prime/.
[NOTES]
Any code should call aos::Init() (or aos::InitNRT() for processes that don't need to be realtime) before making any calls to any of the aos functions.
