-This is a fork from **http://nRF24.github.io/RF24** which can be build as a static library for Atmel Studio 7.
-
-Not all files are needed.
-
-Just copy the following structure into a GCC Static Library project in AS7:
-```
-utility\
-  ATXMega256D3\
-    compatibility.c
-    compatibility.h
-    gpio.cpp
-    gpio.h
-    gpio_helper.c
-    gpio_helper.h
-    includes.h
-    RF24_arch_config.h
-    spi.cpp
-    spi.h
-nRF24L01.h
-printf.h
-RF24.cpp
-RF24.h
-RF24_config.h
-```
-
-Only ATXMega256D3 is supported right now!
-
-## Notes
-The millisecond functionality is based on the TCE0 so don't use these pins as IO.
-
-The operating frequency of the uC is 32MHz. If else change the TCE0 registers appropriatly in function **__start_timer()** in **compatibility.c** file for your frequency.
-
-
-## Usage
-Add the library to your project!
-In the file where the **main()** is put the following in order to update the millisecond functionality:
-```
-ISR(TCE0_OVF_vect)
-{
-	update_milisec();
-}
-```
-
-Declare the rf24 radio with **RF24 radio(XMEGA_PORTC_PIN3, XMEGA_SPI_PORT_C);**
-
-First parameter is the CE pin which can be any available pin on the uC.
-
-Second parameter is the CS which can be on port C (**XMEGA_SPI_PORT_C**) or on port D (**XMEGA_SPI_PORT_D**).
