Question

我的收发器工作正常，因为来自maniacbug的RF24主库的代码工作正常。但我试图学习自己编程，所以我决定来回发送一些整数。它们似乎不起作用。串行监视器打印不同的整数。 TX代码是 -

#include<SPI.h>
#include"nRF24L01.h"
#include"RF24.h"
//#include"printf.h"
RF24 radio(9,10);
const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
const unsigned int transmit =1995;
//unsigned int get = 1;
void setup(void)
{
  Serial.begin(9600);
  //printf_begin();
  Serial.println("lets begin the operation");
  radio.begin();
  radio.setRetries(15,15);
  radio.setPayloadSize(8);
  radio.openWritingPipe(pipes[0]);
  radio.openReadingPipe(1,pipes[1]);
  //Serial.print("now get is  ");
  //Serial.println(get);
  //radio.startListening();
  //radio.printDetails();
}

void loop(void)
{
      //printf("starting the transmission\n");
      Serial.println("starting the transmission");
      radio.stopListening();
      bool ok = radio.write( &transmit, 8 );
      if(ok)
        //printf("ok....transmission successful !!!");
        Serial.println("ok...transmission successful..!!");
      else
        //printf("faioed to tramsmitt\n");
        Serial.println("failed to transmit");
      radio.startListening();
      unsigned int get;
      bool ok2 = radio.read( &get, 8);
      if(ok2)
      {
        //printf("received the packet successfully\n");
        Serial.println("received the packet successfully");
        //printf("received package is %u\n",get);
        Serial.print("received package is  ");
        Serial.println(get);
      }
      else
        //printf("failed to receive\n");
        Serial.println("failed to receive");
        delay(1000);
}

RX码是 -

#include<SPI.h>
#include"nRF24L01.h"
#include"RF24.h"
//#include"printf.h"
RF24 radio(9,10);
const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
unsigned int transmit = 2014;
//unsigned int get = 0;
void setup(void)
{
  Serial.begin(9600);
  //printf_begin();
  radio.begin();
  radio.setRetries(15,15);
  radio.setPayloadSize(8);
  radio.openWritingPipe(pipes[1]);
  radio.openReadingPipe(1,pipes[0]);
  //radio.startListening();
  //radio.printDetails();
}
void loop(void)
{
  radio.startListening();
  unsigned int get;
  bool ok = radio.read(&get,8);
  if(ok)
  {
    //printf("received successfully\n");
    Serial.println("received successfully");
    //printf("received payload = %u\n",get);
    Serial.print("received payload is  ");
    Serial.println(get);
  }
  else
    //printf("failed to receive\n");
    Serial.println("failed to receive");
  radio.stopListening();
  //unsigned int transmit = 2014;
  bool ok2 = radio.write( &transmit,8 );
  if(ok)
    //printf("ok....transmission successful !!!");
    Serial.println("ok...transmission successful..!!");
  else
    //printf("faioed to tramsmitt\n");
    Serial.println("failed to transmit");
  delay(1000);

}

甚至printf.h头文件在我编写代码时似乎不起作用，但它们在库示例中工作得很好。

检查串行窗口的波特率，大多数9600波特产生问题。尝试检查57600波特率

无法使用arduino和nrf24L01 +收发器进行无线通信
