导入PN532Interface.h时出现 "无此文件错误"

Question

我试图让NFC屏蔽使用SPI通信工作。我完全遵循了所有的说明，就像在Seeed Wiki - NFC屏蔽设置.

这是我试过的代码。

#include <SPI.h>
#include <PN532/PN532_SPI/PN532_SPI.h>

PN532_SPI pn532spi(SPI, 10);
NfcAdapter nfc = NfcAdapter(pn532spi);

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)
}

这是我得到的错误信息

如果您使用的是ArduinoIDE，请使用 Sketch -> Manage Libraries ->Library Manager

• 在搜索栏中输入PN532并安装lib Adafruit PN532 从那里。

这确保了它被放置在正确的目录中。可能你的 libs 和 Afafruit 的例子中的不同。
