how do we transfer data between two arduios using RFM12B rf transceiver module.
please suggest with necessary ideas and programming guide.
i hope to solve this project very soon.
thanks

Thanks.
what about:
-SDI
-SDO
-SCK
-nIRQ
-nSEL

how do we conect this to serial port having:
-MISO
-MOSI
-SS
-SCK

I bought a pair of RFM12B transceiver. I am new to rf world and having problem using it.
if someone has already used it,
please guide me basically.
thanks.

hayankata

thanks dude.
thanks a lot, if i get further confusion, i'll be replyimg.

Can we send anologue signal through this rf transceiver.
such as transmitting songs from ipod to its own receiver.

hayankata

if we convert analogue signal like music to digital form.
is there chances of transmission of our signal.

hayankata

which of ther rf module would be applicable for analoge signaling.

And the bandwidth is only a tiny fraction of what you would need for even low-quality audio.


To be picky that's not true for high-compression formats like Ogg Vorbis (48kbit/second - and yes I mean bits not bytes).  And its pretty good quality...  Of course the issue of compression/decompression isn't something you can gloss over!

The drivers/libraries from the jeenode work great on normal arduino type boards, I've played with them a decent bit.
He (the jeelabs guy) makes a breakout board for it now too, much nicer than having to convert to 3.3v and solder tiny wires on little pads.

i installed the library of RFM12 from jeenodes.
i compiled the example sketches, all of the examples shows error notice at the time of compile process.

hayankata

i instaled jeenode liberary, and
but all of the examples code shows error while burning.

Did you include both the rfm12b library and the ports library?
The rfm12b lib requires the ports lib to function.
