* RFM01 simple library |

* $HeadURL: svn://www.mlab.cz/home/MLAB/Designs/duckweed_collector/SW/library/RF02/RF02.cpp $ |
* $Id: RF02.cpp 2129 2011-08-18 18:40:43Z kakl $ |
* draft version v 0.1, experimental |
* |
* code based on the code of "benedikt k." and "contrechoc" |
* code based on the code of "benedikt k." |
* this was an avr project from the site: http://www.mikrocontroller.net/topic/65984#541030 |
* |
* tested on arduino 22 |
* |
* code should be matched with RF01 |
* |
* up to now no transmission between the RF12 modules and Jeelabs.com RF12 lib |
* |
* this code has worked: transmitting using atmega168 and atmega328 in combination with RF01s and RF02s |
* |
* arduino 18 |
