Nano + RFM12b

Hi
Please, could someone tell me the arduino nano pins, unsing real names* that i have to use to connect rfm12b. I have seen several examples but they use general arduino pin numbers but nano pin numbers are diferent ...

If possivel, source code would be also very appreciated because the samples seen use ports.h and I can not find it and because i am also a beginner.

Thanks a lot

Alex

If you check in the "Networking, Protocols, and Devices" section of this forum, there have
been a lot of past threads about RFM12s.

EDIT: what you're trying to do is an enormous, repeat enormous, PITN for a beginner.
You can find reference to the RFM12 here, but you'll have to enter "RFM12" in to the
search box to find the info [Playground has totally diabolical lack of indexing - DUH],
http://playground.arduino.cc/Main/InterfacingWithHardware

This leads you to here,
http://jeelabs.org/2009/02/10/rfm12b-library-for-arduino/
The problem is JeeLib is a horrendously written library, despite the noobish glorifying
comments, and the example sketches don't work properly. Both me and someone else
around here wasted a lot of time with that site.

Personally, I would recommend trying either the nRF2401+ modules, or even the RFM22B
modules, as the former have easy to use s.w., and the latter has a library plus example
code written by mikem, which actually works great without serious bugs.

Of the different modules, the nRF2401+ are easiest to interface the hardware, and
the pins are also 5V tolerant [requires 3.3V power however]. Another option is XBee, and
these are the easiest to use, IF you get a well-designed shield.

2ND EDIT: Sorry, to find RFM12 on the Playground page, you have to use the "Find" box
of your browser to search on "RFM12", and NOT the Search box on the page, as that will
take you straight to nowheres-ville.

Well it needs the SPI pins at least, and its 3.3V only I seem to remember - is the nano 3.3V or 5.0V ? If the latter you'll might need level-shifting.
