RFM12B and AVR The RFM12B tranceiver module has become quite popular recently due to its low price comparing to other modules on the market. But many people nd it hard to make these tranceivers work (mainly because of buggy programming guide provided by manufacturer, I guess...). This short article contains compact and simple code that can be used just to get these modules running for the rst time. It is based on manufacturer s examle code with slight (but crucial) changes.
