Hello.
Thanks for answers.

Is there some progress or stable/final/tested code for Atmel newer RF
chips on ZigBit (ATZB) modules ?
We used the ATZB900 and ATZB24 modules without a problem, with a new platform
of course. We dropped the atzb24 in
favor of the rfa1, and we dropped the atzb900, because it was very hard to get
it in larger quantities, it's
expensive, hard to solder on, and we want to use the rfa1's better timer stack.
I am using http://www.an-solutions.de/products/900_mhz.html
(mega1281+rf212) and preparing migration to rf212b.
And original zigbit/meshbeen (mega1281+rf230).
RF:
- AT86RF233 - compatible with RF230 ?
- Atmel module - http://www.atmel.com/tools/ATZB-RF-233-1-C.aspx
Some references:
- http://wiesel.ece.utah.edu/projects/10/
- git://wiesel.ece.utah.edu/tinyos/tinyos-prod.git (branch wiesel)
With small modifications:
http://www.atmel.com/ja/jp/Images/Atmel-42198-Migration-from-AT86RF230-to-AT86RF233_AP-Note_AT02601.pdf
The problematic parts: PREP_DEEP_SLEEP, TX_AUTO_CRC_ON, probably more,
especially with HWACK.
Is the WIESEL/WREN project driver modified acording to this pdf or only
"renamed" files & components (Can http://wiesel.ece.utah.edu/ answer this question?) ?
I don't know much about xmegas, but they seemed very different from atmegas, so
it will probably hard work to make
the basic drivers. It's probably doesn't worth it: The ARM based MCUs are much
more intresting, and it seems the
industry moves towards ARM.
Yes, Xmega is different but it may be possible to implement TinyOS on it (with atmel bundles).
Yes, ARM (Cortex M0+/M3) is probably right way.
This leads me to new questions:
What is the timeframe of updating
https://github.com/tinyos/tinyos-main/tree/master/packaging ?
AVR - to newer toolchain to support new devices (TinyOS: AVR binutils 2.22
+ gcc 4.6.2 + libc 1.8.0) (Atmel: AVR binutils 2.23.2 + gcc 4.8.1 + libc 1.8)
( http://distribute.atmel.no/tools/opensource/Atmel-AVR-GNU-Toolchain/3.4.3/ )
I do some tests on my Solaris/OpenSolaris platform with some issues
( https://github.com/tinyos/tinyos-main/issues/139 ).
I saw discussion @dev, any progress/timeline ?
ARM - add & check support for ARM Cortex (not only Atmel)
(for example
http://distribute.atmel.no/tools/opensource/Atmel-ARM-GNU-Toolchain/4.7.4/ )
Does ARM toolchain need special patching for TinyOS/nescc ?
Thanks, M.C>
