I'm using the unique serial numbers in the atmega328pb to identify and track our products, but there are way more bytes (10) than I really need (2-3).
Anyone know how ATMEL assigns these? Are they just serialized (i.e. can I just use the last 3 bytes), or is there another coding they use?
My coworkers in customer service will be angry if they need customers to read 20 hexadecimal digits... so I'd like to distill this to 3 unique bytes.
(Yes, I could burn a serial number of my choosing in EEPROM, but I'd like to use the built-in one if possible.)
