【问题描述】:
我正在尝试在 NFC shield 和 arduino uno 之间建立连接。我使用的是seeedstudio nfc shield v2.0。
我已上传所有必需的库。但是,当我尝试这段代码时 sn-p;
#include <SPI.h>
#include "PN532_SPI.h"
#include "PN532.h"
#include "NfcAdapter.h"
PN532_SPI interface(SPI, 10); // create a PN532 SPI interface with the SPI CS terminal located at digital pin 10
NfcAdapter nfc = NfcAdapter(interface); // create an NFC adapter object
void setup(void) {
Serial.begin(115200); // begin serial communication
Serial.println("NDEF Reader");
nfc.begin(); // begin NFC communication
}
void loop(void) {
Serial.println("\nScan an NFC tag\n");
if (nfc.tagPresent()) // Do an NFC scan to see if an NFC tag is present
{
NfcTag tag = nfc.read(); // read the NFC tag into an object, nfc.read() returns an NfcTag object.
tag.print(); // prints the NFC tags type, UID, and NDEF message (if available)
}
delay(500); // wait half a second (500ms) before scanning again (you may increment or decrement the wait time)
}
我收到一条错误消息:
NDEF 阅读器 没找到PN53x板子
有人知道我的问题吗?我该怎么办?
谢谢
