C5535 eZdsp Wireless Interface

Other Parts Discussed in Thread: CC2500, CC8530

I'm really enjoying my C5535 eZdsp board. Lots to discover. Many blinking lights.

Does anyone know what boards/products can be added to the 'Wireless Interface' connectors P1 and P3? This interface may also be referenced as a 'Bluetooth/Chipcon' interface in some documents. A search of ti.com produced many wireless boards and I tried to match up connector sizes as none said compatible with ezdsp boards but without much luck. Is the 'Chipcon' interface a standard for 3rd party add-ons?

Thanks.

Hi Robert,

It's meant to use the following module: http://www.ti.com/product/cc2560-pan1325. You can also find it for Stellaris devices (see website)

Thanks for your interest in TI Products and Regards,

Seb

Hi Robert,

We have designed the eZdsps to be compatible with the MAVRK RF modules, which includes many chipcon RF modules like CC1100, CC2500, CC8530 and bluetooth modules like PAN1323.

See...

http://processors.wiki.ti.com/index.php/MAVRK_Introduction#RF_Modules

What is important is the size and dimensions of the connectors and the locations of signals. You can compare any module against the C5535 eZdsp schematics to check for compatibility.

Hope this helps,
Mark

Seb and Mark,

Thank you for your replies.

That is exactly the information I was looking for.

The ezdspc5515 RF connectors do not appear to include SPI interface lines. However the MAVRK pinout listing (http://processors.wiki.ti.com/index.php/RF_Pinout_for_MAVRK) shows them on J1 - pins 16 through 20. Does this mean that the MAVRK pin assignments vary between products?

Hi Mike,

A valid concern, but the SPI signals are actually present on the RF Header (P1, P2) of the C5515 eZdsp - they are muxed with I2S2 internal to the DSP.

You must use the External Bus Selection Register (EBSR) register to select PPMODE into either MODE 3 or MODE 5, then the SPI signals will be present on these pins and the RF Header will be compatible with the MAVRK spec (like below)...

I will get this information onto the wiki page for this board soon.

Hope this helps,
Mark
