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 * } *}
