Other Parts Discussed in Thread: CC2530, Z-STACK, CC2530EMK, CC-DEBUGGER, CC2531

Hi,

According to the document here http://focus.ti.com/lit/sg/slyb134b/slyb134b.pdf the device CC2480 is no longer considered for

ZigBee solution(???)

Instead the 8051 based devices CC2530/1 are recommended, even in many other places it is documented as far inferior architecture to MSP430 in term of

lower performance and higher current consumption.

It is very confusing and I am asking if someone can kindly explain it?

Do I need to invest in tools and time to know the architecture (8051), which I forgot of many years ago and considered it dead?

Regards

Jan

    The recent Z-Stack 2.3 introduced the CC2530-ZNP. The de facto standard in the ZigBee industry today is to use ZigBee Pro to produce certified compliant ZigBee devices, and therefore it behooves the user to consider platforms other than CC2480 (which does not support the ZigBee 2007 specification) for new designs.

    Hi,

     Thanks for that.

    I am looking again at 2530/1 .

    I need only the CC2530-ZNP functionality and want to use an external MSP430 application processor with it.

    Is the Zigbee stack already preloaded into 2530/1 devices or do I need to reflash them?

    If it has to be reprogram, where to find the object code (*.hex or similar) or do I need to recompile the sources?

    Thanks again for your help.

    Install the ZAP (ZNP Application Processor) sample applications:

    http://focus.ti.com/docs/toolsw/folders/print/z-stack.html

    swrc173.zip (46.7MB) - contains ZStack-ZAP-MSP430-1.1.0.exe (the ZigBee Applications processor to be used with MSP430 product family v.1.1.0). Note: See "Compatability Issues" for correct IAR version.

     

    You will see the pre-compiled ZNP images here:

    C:\Texas Instruments\ZAP-MSP430-1.0.1\Projects\zstack\ZAP\ZNP-HexFiles

    Hi DH,

     Thanks for that link and clarification.

    My CC-Debugger is on it's way and I am getting a CC2530EMK as well to play with.

    Are there any plans for CCS version of Z-stack with MSP430 and Stellaris examples?

    Regards

    Hello,

       No plans for CCS version of Z-stack. However, the forthcoming CC2530ZNP examples should be easily portable to any compiler since they don't use any intrinsic functions. I have CC2530ZNP working with MSP430 and will get it working with Stellaris in a few weeks. The only difference is the SPI interface code; I think that's like 1 function. The ZNP makes life much, much easier; I can set up a network with encryption and send data back and forth in <3kB of code on the MSP430 since the ZNP encapsulates all the Z-Stack.

    I'd also recommend getting a CC2531 USB stick ($50) and use TI's free packet sniffer. Helps to see what devices are talking.

    Hi Derek,

     Thank you for your post.

    When yoy start working on a new project, you always have doubts about the right selection of options (devices, manufacturers, ...).

    I did the search for 'CC2530' within IT E2E Community and there is a very few results.

    Does it mean that CC2530 is not popular or it doesn't create any problems to be asked for help with?

    My quess is that there is not a definite answer to the question: What is the best current option for a ZigBee project?

    Best Regards

    Answering the question "what is the best current option for a Zigbee project" is kind of like answering the question "what is the best car". It depends on a lot of factors; how much time you have; how large of volume, what else will it be interfacing with, etc. The CC2530 is probably the best hardware for a lot of Zigbee applications. I like the CC2530ZNP for when I don't have a dedicated firmware resource just to work on getting everything working within the stack.

    Maybe share a little more about your application and we can guide you a little more.

    Thanks Derek,

    Ii is only my university project, but as I like to dig a bit deeper I would like to know the options and

    other peoples experience. Much appreciate your time and advise.
