A reference to the EEPROM cell


<font color="orange" size="+1">'''示例'''</font>

<pre style="color:dimgray">
#include <EEPROM.h>

void setup(){

  unsigned char val;

  //Read first EEPROM cell.
  val = EEPROM[ 0 ];

  //Write first EEPROM cell.
  EEPROM[ 0 ] = val;

  //Compare contents
  if( val == EEPROM[ 0 ] ){
    //Do something...
  }
}

void loop(){ /* Empty loop */ }
