Reference

Include Library

#include <ArduinoUniqueID.h>

Variable: UniqueID & UniqueIDsize

UniqueID has UniqueIDsize bytes array of the Unique Serial ID.

for(size_t i = 0; i < UniqueIDsize; i++)
  Serial.println(UniqueID[i], HEX);

Method: UniqueIDdump

Print the hexadecimal bytes of the Unique Serial ID on the Stream.

void UniqueIDdump(Stream);

Variable: UniqueID8

UniqueID8 has the last 8 bytes array of the Unique Serial ID.

for(size_t i = 0; i < 8; i++)
  Serial.println(UniqueID8[i], HEX);

Method: UniqueID8dump

Print the last eight hexadecimal bytes of the Unique Serial ID on the Stream.

void UniqueID8dump(Stream);
