I apologise to everyone who has been trying to use this module. I was not aware of the difficulties with arduino-0015, atmega 328 etc,

These problems have now been fixed and a new version of the library uploaded to
http://www.open.com.au/mikem/arduino/VirtualWire-1.3.zip

I will try to monitor this BB, or you can email me directly at mikem@open.com.au

Cheers.

How's the progress on making it a class?


mikem

Little progress on the class yet. Main problem is that there is an ISR involved, so I guess it has to be a singleton class.

I'd be inclined to suggest you develop a wrapper class and just automatically instantiate an object (a la Serial / HardwareSerial) and you can probably leave the ISR outside of it--if that works technically.

Similar sort of approach to what the Ethernet library uses (but without the ISR complication).

hi,

hi read about virtualwire and found that it would be useful for some ideas i have. i would like to try it, but i wasn't able to find the receivers/transmitters indicated in the documentation.

I live in italy, near napoli. Is there a place (either web or "physical" shop) where i can find cheap rf transmitters, receivers or transceivers for use with virtualwire library?

I found these on ebay, very cheap (~6$ for a couple tx+rx):

http://cgi.ebay.it/433Mhz-RF-link-kit-including-transmitter-and-receiver_W0QQitemZ320346083288QQcmdZViewItemQQptZBI_Connectors_Switches_Wire?hash=item320346083288&_trksid=p3286.c0.m14&_trkparms=66%3A2|65%3A15|39%3A1|240%3A1318

do you think they can be ok? there it says that the rx output high value is half of Vcc. So i guess i have to feed it with 10V to make the values match with arduino's input pin voltage levels... is it right?

In the end, can i use rf devices working at different carrier frequency (different than 433mhz)?
