Re: [Nanostack-devel] Static NanoStack 1.1.0

[Peter K. <pe...@pk...>]

 Hi,

Sorry for my late response. I didn't have time to work on nanostack. I hope
I'll be able to make a 3 way compare between my static 1.0.3, original 1.0.3
and 1.1.0. To see what would be the best way to go.

Now about the port: I was thinking of creating on include file ( ex.
platform.h ) in place of FreeRTOS includes ( FreeRTOS.h, task.h, queue.h ).
the ifdef for includes between the static and freertos version would be made
in this include.

Currently there are two tasks handling the stack: mac task and stack task.
Those two processes could be joined in one task even for FreeRTOS version.

I've also made my own queue functions. Queue memory allocation is now done
at compile time. Dynamic memory allocation for stack could be removed
completely.
Are there any good reasons to keep using dynamic memory allocation?


Cheers,
Peter

Hi Peter,

Just made the new nanostack-devel mailing list. Please subscribe here:
https://lists.sourceforge.net/lists/listinfo/nanostack-devel

And then lets move this discussion to that list as Martti is also interested
in helping.

I suggest we do it with an app.rules "HAVE_FREERTOS" define, and use IFDEFs
(fun, I know) throughout. That way we can preserve it in the same branch as
FreeRTOS is useful for more powerful processors. It might not hurt to just
use state machines instead of loops also for the FreeRTOS version thus
avoiding some IFDEFs.

Hi,

What do you think would be the cleanest way to make NanoStack static?
What I've currently done with 1.0.3 was removing all  FreeRTOS and
adding lightweight queue support when needed and rewriting some loop
into state machines.

It would be nice if the static changes could be included into the main
branch. But that would probably mean ifdef-ing all of the files.

Hi,

Just got back from Slovenia last night. We had a great end of our
vacation, pretty good luck with the weather ;-) Didn't make it to Bled
in the end, but we went to Bohinj on Wed, beautiful. Now I need to
come back for skiing and hiking in the future!

Dr. Roman Trobec from JSI is the local organizer of that summer
school. He is into signal processing for medical sensing applications.

Network manager is not needed for routing. I think those delays are
related to gateway router timeouts, I will take a look as I don't know
that code very well. Will get back to you on this soon, and will
discuss with Martti too.

Hi Peter,

Here is the info about that summer school.

should there be an attachment???

It was cool to meet you in person, sorry such a short meeting,I would
have liked to talk tech more ;-)

The same

I am now in a taxi to Kranj and back to get medication for my wife's
leg ;-) Luckily we have travel insurance..

Is she ok?

Let's keep in touch about using NanoStack in your product. I kind of
like make an optional version of NanoStack 1.x with a static
implementation instead of FreeRTOS. I'll think about what that means
in practice.

I've basically removed all FreeRTOS dependencies from nanostack and
ported my apps to use the new stack. The port unfortunately doesn't have
the save code base as the FreeRTOS version( it's not just a couple of
ifdefa and macros, although I think it could be. )
The only problem is see is nwk_manager.c. There are a couple of long 15s
delay used there. So this part would have to be implemented in a more
state machine fashion.
Is nwk_manager.c in any way mandatory for routing?

As we also have MSP430 support you could use that in your MSP430 on
your product.

I use MSP430F2011 which is the lowest possible cost MSP with 2k flash
and 128bytes of ram just to do some realtime stuff. So no nanostack
here.

Hi Zach,

Great. I was thinking of going to Bled to visit a friend who is doing
his MBA there. Sometime next week. Or we could also meet in
Ljubljana(1
hour from Bled ).

You have a lot of possibilities starting from Bled. It's a good
starting
point for the mountains. Or our coast(2hours, although I prefer
Croatia
which is about 3 hours from Bled).

Will you be reachable by email? My mobile is +386 31 392 047.

Cheers,
Peter

Hi Peter,

Monday we (with my wife, 2 kids, and mother-in-law) are leaving to
Slovenia for vacation. We will be in Bled until July 3rd with
basically no fixed program.

How about we meet up in person while I'm in Slovenia? Either you
could
hop up to Bled for half a day or I can come down to Ljubljana. I'd
probably like to see Ljubljana anyways as I've never visited.

Cheers,
Zach
