通过串口通信可以方便地控制ESP32对RFID标签的读写操作。 本文将展示如何通过串口消息来控制RC522模块的读写操作。 MFRC522:这是一个支持ISO/IEC 14443A标准的非接触式通信RFID读卡器模块,通常用于读取和写入13.56MHz频率的RFID标签。 串口通信:通过串口发送"READ"命令来读取RFID标签的UID和扇区数据,发送"WRITE [TEXT...
}voidloop(){// Reset the loop if no new card present on the sensor/reader. This saves the entire process when idle.if(!mfrc522.PICC_IsNewCardPresent()) {return; }// Select one of the cards.if(!mfrc522.PICC_ReadCardSerial()) {return; }// Dump debug info about the card; PICC_...
MFRC522模块还有一个重置输入引脚,我将它连接了ESP32开发板的SLC/IO22引脚 (ESP32 GPIO22)。同样,我们需要在软件中指定所使用的这个引脚,当然,您也可以使用其它输出引脚。 由于未使用IRQ引脚,所以我们将悬空IRQ引脚。这个引脚与中断功能有关。 软件库文件 ...
