Introduction

This documents the library for the nrf24L01+ radiomodule of Nordic Semiconductors for Atmel Xmega devices. This driver is based on:

the the C++ driver from J.Coliz (a.k.a maniacbug)
Optimized High Speed NRF24l01+ Driver Class Documentation v1.1.4
the C driver for the STM32 of TKJElectronics
the C-driver for the HvA Xmegaboard version 2 of Wouter Zylstra (Internal HvA).

Other references:

the library and documentation by S. Brennen Bal, see DIYEmbedded
the AVR-Lib/nRF24L01 of Tinkerer's Playground
Nordic Semiconductor, nRF24L01p Product Specification 1.0. nRF24L01p_Product_Specification_v1_0.pdf

The library consists of two c-files and two h-files

`nrf24L01.c`	generice functions for nrf24L01p
`nrf24L01.h`	generic macros and prototypes for nrf24L01p
`nrf24spiXM2.c`	functions for SPI interfacing with HvA-Xmegaboard
`nrf24spiXM2.h`	macros and prototypes for SPI interfacing with HvA-Xmegaboard

There are two accompaigning test programs

`nrf24_test_send.c`	test program for sending data
`nrf24_test_receive.c`	test program for receiving data

Setup

To use the library:

Place nrf24L01.c, nrf24L01.h, nrf24spiXM2.c and nrf24spiXM2.h in your project folder.
Add nrf24L01.c and nrf24spiXM2.c to your project.
Initialize the nrf24L2401p with init_nrf()
Use for instance nrfWrite() and nrfRead() to write to and read from nrf24L01p

An example is enclosed in the zip. This example consists of two programs nrf24_test_send.c for the sender and nrf24_test_receive.c for receiver. The example needs two HvA-Xmegaboards, or two Xmega's and two radiomodules.
