Complete RFM69HW control, WMBus library?

[papadeltasierra]

Just come across these boards and I might have a use for one as a WMBus receiver.  Do I have the ability to fully program the RFM69HW (i.e. write the various registers), catch the receive bytes and then write my own minimal WMBus library to decode the results?
In case anyone is interested, I'm currently using an RTL-SDR to try and read my water meter and if this works would like to replace that 'PC-plus' monster with a low power solution and the moteino looks like it might be an option.

You can very easily call the readReg(addr) and writeReg(addr, value) routines from your main code if you want to have lower level control over your transceiver.  You will need to park some of your code in the INT0_vect since a lot of what happens with the radio is interrupt driven but as long as that doesn't bother you, Felix's library should work fine for what you want.
