💾 107-Arduino-UniqueId

This library provides a unique 64-bit ID over various Arduino platforms.

Such a feature is useful for the Cyphal protocol and it's Arduino port 107-Arduino-Cyphal but naturally can also be used in another context.

This library works for

• ArduinoCore-samd: Arduino Zero, MKR 1000, MKR WiFi 1010, Nano 33 IoT, MKR GSM 1400, MKR NB 1500, MKR WAN 1300/1310 ✔️
• ArduinoCore-mbed: Portenta H7, Nano 33 BLE, Nano RP2040 Connect, Edge Control ✔️
• arduino-esp32: ESP32 Dev Module, ESP32 Wrover Module, ... ✔️
• arduino-pico: Raspberry Pi Pico, Adafruit Feather RP2040, ... ✔️
• adafruit/ArduinoCore-samd: Adafruit Feather M4 CAN Express, ... ✔️
• ArduinoCore-renesas: Portenta C33, Uno R4 WiFi, Uno R4 Minima, ... ✔️

Example

#include <107-Arduino-UniqueId.h>

void setup() {
  Serial.begin(115200);
  while (!Serial) { }

  Serial.println(OpenCyphalUniqueId);
}

void loop() { }
