hi guys
got another question for you, does anyone know how to get the Maplin Wireless Chip working with the Arduino (Maplin Order Code: A60JN)
i have had a look at the Data Sheet for it and i cant make heads or tails of it, all i want to do is send some data wirelessly between two arduinos using two of those chips (A60JN)
thanks guys!
heres the link to the datasheet for it
i am completly new to using SPI with the arduino and any help on how to read/write to SPI would be much appreciated as i dont understand the examples on the arduino website
Reading/writing via SPI is pretty straightforward.
NickGammon has a great writeup.
Here ya go, give this a read
"An Arduino compatible library for the ALPHA Transceiver"
From the looks of the d/s, that's what everyone else in the world knows as a
HopeRF RFM12.

There have been many threads on this in the Networking section, plus the jeenode is
based on this. You'll also do better to look at the lowpowerlab s.w., rather than the
jeenode s.w., if you don't want to pull all of your hair out.

knew i had come to the right place, i will try out the lowpowerlabs library and see if it works, looks like a nice easy library
Be sure to report back on how it goes with the lowpower library, then we'll know
what to tell the next guy, :-).
dont worry, i will do, i have some spare time tomorrow to set it out with so u should get a reply tomorrow evening
FYI: SPI works like a pair of shift registers, one in the Master and one in the SLAVE.
On each clock:
A bit gets shifted out of the Master shift register and into the Slave shift register via MOSI (Master Out/Slave In).
A bit gets shifted out of the Slave shift register and into the Master shift register via MISO (Master In/Slave Out).
The SPI.transaction() function sends 8 bits to the Slave and simultaneously receives 8 bits from the Slave.
Because the receive and send happen simultaneously you typically have to do one transaction to send a command and a second to receive the result. Often for the second transaction you send 0.
sorry guys, i started to build the circuit and realised i dont have the right IC Holders at the moment to build it (I build an arduino board whenever i need it for a project so it looks more integrated with the circuits) so i cant test out the library tonight, im away this week too so it wont be till next week i am able to test out the library, sorry guys
The bare smt modules are a little difficult to solder to without a specific adaptor. These
guys sell the same thing but with DIP headers,
Alternatively, what I've had success with is to hold the modules down on pcb/fiber board
using double-sided tape, and then solder #30 wire [wirewrap size] to the needed pins, to
make connections. If you overheat the side-on pads or apply too much pressure [eg, by
trying to use larger wire], they'll fall right off, and break the miniscule 6-mil traces. Then
you're toast.
