How do I get a unique ID for a W5500 Pi Pico using Arduino IDE?
I have many picos controlling sensors on my network. I want to generate unique MAC addresses for them (using the unique ID) so I can keep them organized in my Postgres database which is controlled by django. Right now everything is built through Arduino IDE. I am trying to generate a HTTP POST with the MAC address and firmware version, but I can't figure out how to properly generate a MAC address without switching up my entire toolchain. I am using Ubuntu 24.04 LTS
