About

This is a simple library to drive the nRF24l01+.

Hardware

This uses the commonly available breakout. The connections are shown below /media/uploads/epgmdm/nrf24l01pinout.png

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
*   }
*}

Use case: For a simple receiver

rx code snipet

#include "NRF2401P.h"
*int main(){
*        
*  long long addr1=0xAB00CD; // setup address - any 5 byte number - same as TX
*  int channel =0x12;  // [0-126] setup channel, must be same as TX
*  bool txOK;
*  char msg[32];
*  char ackData[32];
*  char len;
*
*  // Setup 
*  NRF2401P nrf1(PTD6,PTD7, PTD5,PTD4, PTC12); //mosi, miso, sclk, csn, ce)
*  nrf1.quickRxSetup(channel, addr1); // sets nrf24l01+ as  receiver, using pipe 1
*
*  // set ack data
*  sprintf(ackData,"Ack data");
*  nrf1.acknowledgeData(ackData, strlen(ackData),1); // ack for pipe 1
*    
*  // receive
*  while (! nrf1.isRxData()); // note this blocks until RX data
*  len= nrf1.getRxData(msg); // gets the message, len is length of msg
