I want to generate guids to name a set of different files. The main restriction I am having is the fact that I need to implement this in an embedded microcontroller with an RTOS.

The main UUID/GUID libraries i've found are linux/windows based, but don't work for my case. Is there a simple, lightweight implementation available I could use? or I would need to generate my own GUID generator?

Edit: The MCU does have a random number generator and a real time clock.

    Do you have a random number generator on your platform? `don't work for my case` - why do they not work for your case? [Generating UUID is not that much](https://www.cryptosys.net/pki/uuid-rfc4122.html). The site even gives [source code](https://www.cryptosys.net/pki/Uuid.c.html). – KamilCuk Oct 29 '19 at 12:28

    I assumed that if it requires a linux based system I could not use it on my MCU. – Asan Oct 29 '19 at 12:30

I solved the issue using GUID. Initially I thought I could use this only on linux based systems but turns out it can also be used for the MCU and the implementation is quite light weight.

The procedure to generate the GUID comes from this website which also provides the sourcecode of the UUID.c library.
