About
This is a simple library to drive the nRF24l01+.
Hardware
This uses the commonly available breakout. The connections are shown below 
Software
Use case: For a simple transmitter
tx code snipet
#include "NRF2401P.h"
int main() {
*
* long long addr1=0xAB00CD; // setup address - any 5 byte number - same as RX
* int channel =0x12; // [0-126] setup channel, must be same as RX
* bool txOK;
* char msg[32];
* char ackData[32];
* char len;
*
* // Setup
* NRF2401P nrf1(PTD6,PTD7, PTD5,PTD4, PTC12); //mosi, miso, sclk, csn, ce)
* nrf1.quickTxSetup(channel, addr1); // sets nrf24l01+ as transmitter
*
* // transmit
* strcpy (msg, "Hello");
* txOK= nrf1.transmitData(msg,strlen(msg));
*
* // read ack data if available
* if (nrf1.isAckData()) {
* len= nrf1.getRxData(ackData); // len is number of bytes in ackData
* }
