Would like a OMV Unique ID


I would like to use a unique ID for my OpenMV H7 that no other device could have. The number coming back from omv.board_id() is 12 bytes long, I am ideally looking for something that is 8 bytes long.

Is there anyway I can get a unique ID for the H7 board from this 12 byte long string that is 8 bytes long?

Thanks for your help,

No only the 96 bits number is guaranteed to be unique across devices.

Thanks for the reply, I didn’t realise it was an existing value in the STM32 itself.
