Flo rian / RF22KL25Z

Library for HopeRF RFM22 transceiver module ported to mbed. Original Software from Mike McCauley (mikem@open.com.au) . See http://www.open.com.au/mikem/arduino/RF22/

Fork of RF22 by Karl Zweimüller

Revision:
9:46fb41f4259d
Parent:
5:0386600f3408 
changed the LED default numbers in the RF22 constructor as the former values interfered with pins used on an KL25Z board. The library didn't work with those.

Who changed what in which revision?
