| * draft version v 0.1, experimental |
| * 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 $ |
| * |
| * code based on the code of "benedikt k." |
| * this was an avr project from the site: http://www.mikrocontroller.net/topic/65984#541030 |
| * code based on the code of "benedikt k." and "contrechoc" |
| * |
| * 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 |
