Sure thing! 这是一个基于 Ardunio 的控制 PN532 可读写数据的代码:
#include <Wire.h>
#include <Adafruit_PN532.h>
// Create an instance of the PN532 class
Adafruit_PN532 nfc(PN532_SS);
void setup(void) {
// Initialize the serial communication
Serial.begin(9600);
// Initialize the PN532 class
nfc.begin();
// Configure the board to read Mifare cards
nfc.SAMConfig();
}
void loop(void) {
// Check if a card is present
if (nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, &uid[0], &uidLength)) {
// If a card is present, print the UID
Serial.print("Found card with UID: ");
for (int i = 0; i < uidLength; i++) {
Serial.print(uid[i], HEX);
Serial.print(" ");
}
Serial.println();
// Write data to the card
uint8_t data[16] = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0xFE, 0xDC, 0xBA, 0x98, 0x76, 0x54, 0x32, 0x10};
nfc.ntag2xx_WritePage(4, data);
// Read data from the card
uint8_t buffer[16];
nfc.ntag2xx_ReadPage(4, buffer);
Serial.print("Data read from card: ");
for (int i = 0; i < 16; i++) {
Serial.print(buffer[i], HEX);
Serial.print(" ");
}
Serial.println();
}
// Delay for 1 second
delay(1000);
}
请注意,这只是一个简单的模板代码,需要根据您的具体 PN532 控制器进行调整。如果您需要更多的帮助或指导,请告诉我。
