Method readUniqueId

SPIFlash.cpp:136–147

Get the 64 bit unique identifier, stores it in UNIQUEID[8]. Only needs to be called once, ie after initialize Returns the byte pointer to the UNIQUEID byte array Read UNIQUEID like this: flash.readUniqueId(); for (uint8_t i=0;i<8;i++) { Serial.print(flash.UNIQUEID[i], HEX); Serial.print(' '); } or like this: flash.readUniqueId(); uint8_t* MAC = flash.readUniqueId(); for (uint8_t i=0;i<8;i++) { Ser

/// or like this:
/// flash.readUniqueId(); uint8_t* MAC = flash.readUniqueId(); for (uint8_t i=0;i<8;i++) { Serial.print(MAC[i], HEX); Serial.print(' '); }
uint8_t* SPIFlash::readUniqueId()
{
  command(SPIFLASH_MACREAD);

  SPI.transfer(0);
  for (uint8_t i=0;i<8;i++)
    UNIQUEID[i] = SPI.transfer(0);
