商品說明

Grove – NFC Tag 近場通訊標籤模組

Grove – NFC Tag 是一款基於意法半導體M24LR64E-R集成解決方案的近場標籤模塊。通過I2C接口與主機通信，內建64位唯一識別碼同時集成了64Kbit EEPROM。模塊外擴了一個PCB天線，可以很方便安裝到您設計的結構中。

規格

• 工作電壓:5V or 3V3
• 工作電流<1mA
• 識別距離< 2cm
• 工作頻率: 13.56MHz
• 符合ISO 15693 and ISO 18000-3 1標準
• 64-bit 唯一識別碼(UID)
• I2C 接口通信
• Grove 接口

應用實例

手機讀寫模塊

1. 下載安裝NfcV-reader for Androud and install it
2. 啟動手機軟件，可以按照以下步驟讀寫標籤

控制LED燈

1. 硬件如下圖所示連接

1. 下載NfcV-reader for Androud，安裝
2. 下載NFC Tag Lib重命名為“NFC_Tag_M24LR6E”並且把次文件添加到Arduino’s庫裡面.
3. 打開Arduino IDE. 如果Arduino IDE已經打開,重啟以下.
4. 在Arduino IDE,點擊: File -> Example -> NFC_Tag_M24LR6E -> ledControl
5. 下載完程序，現在可以通過手機去控制LED燈啦

 
#include "NfcTag.h" 
#include <Wire.h>
 
NfcTag nfcTag ; 
int led =  5 ; 
bool flag =  false ; 
bool preFlag =  false ; 
void  setup ( ) { 
  Serial . begin ( 9600 ) ; 
  pinMode ( led, OUTPUT ) ; 
  nfcTag. init ( ) ; 
}
 
void  loop ( ) { 
  flag = nfcTag. readByte ( EEPROM_I2C_LENGTH - 1 )  ==  0xff ? true : false ; 
  if ( flag ! = preFlag ) { 
    Serial . println ( "get remote NFC control signal!" ) ; 
    if ( flag ==  true ) { 
      Serial . println ( "led will light up!" ) ; 
      digitalWrite ( led, HIGH ) ; 
    } else { 
      Serial . println ( "led will turn dark!" ) ; 
      digitalWrite ( led, LOW ) ; 
    } 
    preFlag = flag ; 
  } 
  delay ( 5 * 1000 ) ; 
}
