I'm still trying to get my head round exactly what can and can't be achieved with these devices, but I'd like to try the following:
I've found a guide for interfacing with home automation equipment here. It demonstrates using a particular transceiver. I'd like to know whether it's possible to use a different transceiver, in particular this one (because of the frequency range). I'm assuming that it's just a case of mapping the pins to the relevant GPIO sections, and then tweaking the code. Is there anything glaringly obvious that I'm missing?
I have a degree in Computer Science and spend a lot of time programming in .NET so the programming side of things doesn't bother me, but the hardware side is completely new!
Edit: I've a feeling that most of the information that I need will be in this PDF. It shows the pin layout and also goes in to a lot of details about how to actually use the chip.
I'd also like to mention that if I get this working I plan on writing up my experience with it in a guide in a similar fashion to the one that inspired me.
