Propeller is for the hardware as Linux is for the software?

I understand that in Propeller the code can not be protected as a PIC. Right?
The code is freeware, shareware or copyright?
If i build a board I can sell the board using
the code of third-party or not?
If i can contact the author is easy to understand
and ask him whether or not to authorize use the code,
but if I can not contact them I can not use it.

it is my assumption and had a confirmation,
that is how it should be classified code for the Propeller?
it is free or not?

Take a look
Code found in the forums is generally a good idea to contact the author by PM or email
and let them know what you have in mind and ask permission for use.

New to the Propeller?
Getting started with a Propeller Protoboard?

If the code is on the obex exchange then it is covered by an MIT licence - see the obex exchange for rules.
If the code is published on the forums, then check the licence in the code. If not, ask the writer
Basically, if it is under MIT license you are free to use it how you like and the brief terms are usually at the end of the file.
There has been a thread that discussed this a while back (months). Use Google Advanced search to search the forums.parallax.com
Hope this helps

Thanks OBC for adding the MIT licence.
I think you also may be asking if the code can be protected in the propeller. The answer is probably not as far as someone stealing your code. The PropII may have such a feature.

accustomed to microcontrollers with possibility
to protect the code, I was not accustomed to
thinking of how he once with the Z80 or 8031
where the code was placed on EPROM.
The Propeller·is unique and I have to get used
to this new approach,
from what I see in this forum, your choice on
Propeller is winning, because it allows a large
share of those who use and allowing both to
do business for those that sell hardware

This is interesting to think about; in the days of
Z80 and 8031, I don't recall ANY concern about
copying EPROMs, and that's probably because
the chips and programmers were expensive and
useless to most people.
At worst, maybe they were hacked in TV descramblers.

beautiful, a piece of history, would be even more beautiful if
the author had been consistent. Uncle Bill has made money
by acting copyer, not a developer, has copied a lot of software,
preferring to pay fines for lost causes, in the face of huge gains,
did you ever wonder why there are pirated copies of its so and its
programs (CLOSED)? very simple, is a seed, you learn to use that
operating system and spread like a virus, in the end everyone
knows that "only" use the system and become a monopolist.
Linus Torvalds arrived late with its Linux, if it had arrived 20 years before,
Bill Gates would not have magnified so much, but it is history and we can
not change.
Many people have copied my things without ever appoint my name,
here·an example of poor ZIF made from hooves of a low
cost to program the PIC.

I have always been opposed to magazines that publish
articles with closed microcontrollers, for which not learn anything
and you must buy the chips closed.
In our Home Page, we created a system of exchange projects,
at registration will receive a·number of virtual credits (100)

and accumulate credits by sending projects,
this will protect the authors·and we·have a high·number

"but it is history and we can not change."
Well we cannot change the past but the situation is being actively changed everyday. Slowly the world is realizing it does not want to be forever tied to a monopoly supplier of closed so called standards.
As a simple case look what has happened here with the Propeller development tools. Parallax only supports Windows. Their customers want cross platform tools. Now there are multiple Spin compilers, assemblers, debuggers etc that are cross platform.
As our project leaders said to me whilst I was working at Nokia "I don't want Bill Gates' fingers in my project any more than is absolutely necessary".
That letter from Bill is quite famous and often contrasted with Linus' announcement of Linux www.linux.org/people/linus_post.html

of the propeller and its philosophy, and I am sure that if this component has spread,
other manufacturers of microprocessors will have to adapt.
