以下是nrf24l01 dsss示例代码,使用Arduino Uno和nRF24L01模块:
```c++
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
RF24 radio(9, 10);
byte addresses[][6] = {"1Node","2Node"};
void setup() {
Serial.begin(9600);
radio.begin();
radio.setDataRate(RF24_1MBPS);
radio.setPALevel(RF24_PA_MAX);
radio.setAutoAck(1);
radio.setChannel(76);
radio.setPayloadSize(8);
radio.setAddressWidth(6);
radio.openWritingPipe(addresses[1]);
radio.openReadingPipe(1,addresses[0]);
radio.enableDynamicPayloads();
radio.enableDynamicAck();
radio.enableDSSS();
radio.startListening();
}
void loop() {
if (radio.available()) {
byte received[8];
uint8_t len = radio.getDynamicPayloadSize();
radio.read(received, len);
Serial.print("Received: ");
for (int i = 0; i < len; i++) {
Serial.print(received[i]);
Serial.print(" ");
}
Serial.println();
}
byte payload[8] = {1, 2, 3, 4, 5, 6, 7, 8};
radio.write(payload, 8);
delay(1000);
}
```
此示例使用动态负载和自动应答功能。在设置中启用DSSS,设置通道为76并设置数据速率为1Mbps。开启接收管道1并打开写入管道,然后开始监听。在循环中,如果有数据可用,则读取并打印该数据。然后,将数据发送到另一个节点。此示例使用地址“1Node”和“2Node”作为节点地址。
