Interface C5535eZdsp and CC2530

Stefano Tennina

Other Parts Discussed in Thread: CC2530EM, CC2530

Dear Sirs,

with some colleagues we developed an application for wireless transmission scheduling, e.g., for sensor nodes weared by a human. In this application a gateway was constituted by a wireless node communicating with a netbook through USB.

Now, I'm interested in improving this application by including the power of a DSP to compute FFT. I've got a C5535 eZdsp board and I'm wondering to use it for this purpose.

More in details, a node CC2530 should play as gateway collecting RSSI from the other wireless nodes, then I would like to use the DSP on the C5535 to run a FFT-based analysis on such RSSI samples. The C5535 has the interface to plug a CC2530EM node, however, I'm having difficulties in finding any basic code to start from.

In other words, my question is: is there any example which configure the C5535 board and the CC2530EM for a very simple message passing (even a simple echo application) between them?

Any help and pointers would be appreciated.

Thanks.

There are C5535 FFT implementation sample codes downloadable from:

Please also refer to the FFT section in the System User's Guide.

Dear Mr. Tsang,

thanks a lot for your kind answer.

Unfortunately, my concern is not about how to implement the FFT algorithm on the DSP, for which I appreciate anyway the library you suggested.

Indeed, my concern is about how to allow the two devices (CC2530 and C5535) communicate between each other. Since the C5535 eZdsp development board (http://www.ti.com/tool/tmdx5535ezdsp) has the socket where to plug boards such as the CC2530EM (http://www.ti.com/tool/CC2530Em), I hope there is a (simple) way to configure both to communicate. I would expect a couple of example applications for Code Composer Studio (for the DSP side) and IAR (for the CC2530 side).

Any help?

Best regards.

Stefano

Hi Mr Tsang,
I am trying to do a similar thing with the CC2530 and C5535. I was wondering if you were successful in finding some sort of a starter code to interface the CC2530 with C5535 and be able to send decisions out? Please let me know if you were able find something.

Thanks,

Sorry but I do not have any example. Hope other community members can help.
