Using CC2520 + chip running Linux on an ARM core

Other Parts Discussed in Thread: Z-STACK, CC2520, CC2530, CC2531

I am interested in using the 2520 Transceiver chip such that it is connected through SPI to another chip running Linux on ARM. How much will I be able to leverage from the Z-Stack that is provided by TI? I am also interested in the Smart Energy and Home Automation Profiles.

    Hi,

    I don't think the cc2520 can handle Z-stack, it's only tranceiver after all.

    If you want to integrate ZigBee intoyour own board (based on ARM) that

    is running Linux, you can try the CC2530/1 SoC which is a modified 8031

    with 2.4 tranceiver + several peripherals. This SoC can run Z-stack, particularly

    solution that is called ZNP, and can be interfaced directly to the arm through

    UART, SPI, or  USB (in case of CC2531)

    Thanks Igor. 

    I am not expecting the CC2520 to run the Z-stack. I was hoping to run it on a chip I already have, which has a powerful ARM subsystem. A CC2530 can certainly be used, but I am pretty sure it is more expensive than the CC2520.

    Given the time frame I have in mind to put a system together for a demo,  I was hoping to leverage the Z-stack I get off the shelf from TI and adapt it to run on the ARM. Is it possible?

    Hi,

    Sorry for the late reply.

    I think here lies the (bitter) answer for your question.

    On the side note, I heard about something called Contiky and another roumor

    about ZigBee stack (not Z-stack) related to Contiky's (try to search for it in the community

    forums maybe you will fish something out).
