我想将RF24连接到Arduino Due,但它无法正常工作。 Arduino Due板运行在3.3,所以我需要使用逻辑电平转换器,因为RF24引脚使用5v,Vcc(3.3v)除外。我将MISO / MOSI / SCK连接到电路板上的ICSP接头,并将CSN连接到引脚10,将CE连接到引脚9。
代码:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(9,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int LED1 = 13;
void setup() {
Serial.begin(115200);
pinMode(13, OUTPUT);
digitalWrite(13, LOW);
delay(20);
pinMode(10, OUTPUT);
radio.begin();
radio.setRetries(15,15);
radio.openReadingPipe(1,pipe);
radio.setPALevel(RF24_PA_LOW);
radio.printDetails();
radio.startListening();
}
void loop() {
byte gotByte;
while( radio.available()){
radio.read( &gotByte, 1 );
Serial.println(gotByte);
}
}
输出(printDetails
):
STATUS = 0x00 RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=0 TX_FULL=0
RX_ADDR_P0-1 = 0x0000000000 0x0000000000
RX_ADDR_P2-5 = 0x00 0x00 0x00 0x00
TX_ADDR = 0x0000000000
RX_PW_P0-6 = 0x00 0x00 0x00 0x00 0x00 0x00
EN_AA = 0x00
EN_RXADDR = 0x00
RF_CH = 0x00
RF_SETUP = 0x00
CONFIG = 0x00
DYNPD/FEATURE = 0xff 0xff
Data Rate = 1MBPS
Model = nRF24L01
CRC Length = 16 bits
PA Power = PA_MAX
输出没有意义,我做错了什么?
