使用 RaspberryPi 和 arduino 无线发送数据

如何解决使用 RaspberryPi 和 arduino 无线发送数据

我已经安装了以下版本。但是我无法通过 arduino uno 向带有 nrf24l01 的 raspBerrypi 发送无线数据。

我正确输入了 RaspBerrypi 和 Arduino 连接引脚。

我无法发送任何数据。但我的链接是正确的。

你能帮忙解决这个问题吗？

我在 arduino 端使用的代码

Arduino uno - 客户端

#include <SPI.h>
#include <nRF24L01.h>
#include "printf.h"
#include <RF24.h>
#include <RF24_config.h>

int address = 0x28; // 28 is the address
byte byte1,byte2,byte3,byte4;
RF24 radio (7,8);
const uint64_t cihazlar[3] = { 0x0E314E6F6465,0x0E324E6F6465};

struct dataStruct {
  int p1; 
  int t1; 
} transmitter2_data;

void setup()
{
  radio.begin();
  radio.setChannel(76);
  Serial.begin(9600);
  
  printf_begin();
  radio.setRetries(15,15);
  radio.enableDynamicPayloads();
  radio.setDatarate(RF24_250KBPS);
  
  radio.openWritingPipe(cihazlar[0]);
  
  radio.stopListening();
  radio.printDetails();
}

void loop()
{
  transmitter2_data.p1 = 300;
  transmitter2_data.t1 = 400;

  bool ok = radio.write(&transmitter2_data,sizeof(transmitter2_data));

  if (ok)
  {
    Serial.println("ProMini 2");
    Serial.println(transmitter2_data.p1);
    Serial.println(transmitter2_data.t1);
    Serial.println(transmitter2_data.s1);
  }
  else
  {
    Serial.println("it Failed to send");
  }
  delay(1500);
}
