+avr_radio_power
+===============
+
+Motivation
+-----------
+Spins over different radio seting for the Atmel radio. The motivation is to 
+get understanding and also to get correct data for avrora and Contiki
+ simulations. Program loops over different TX-power setting and measures 
+RX consumption also radio off and idle power use in SLEEP_MODE_PWR_SAVE is 
+measured. Program disables radio duty cycling (RDC) and sets MCU in deep 
+sleep mode to only get radio consumption.
+
+Usage
+-----
+The different setting is printed on the terminal. You need a way to measure 
+the current consumption and relate to the tests.
+ 
+Example
+-------
+Program printout with added measurements. The used board was RSS2 mote 
+with a AtMega256RFR2 CPU. Max is when 0xFF is written to the RPC register.

+  
+Comments
+--------
+We see TX consumption decreases from 17.80 to 14.63 mA using Max RPC (0xFF).
+NOTE! For RX 13.43 to 7.11 mA. Nice. This actual measurements. 
+The avr-rss2 port adds support for the AtMegaXXXRFR2 including the new RPC 
+function.
