MSP430FR6047: Problem related to Implementation of Random Number Generator(True Random Seed)

Hello

Please refer to the random number generator code from this example:

Thanks

I am getting this error on your link.

Just pull as many bytes as you need from this area of the TLV:

Note, that just because the seed is random, it does not mean that any random numbers generated are cryptographically secure.

The Wayback Machine has a copy of that page which doesn't address using the random number in the TLV. Instead it describes building a RNG using the difference between the VLO and ACLK.

The normal way to use the value in the TLV is to seed some pseudo RNG such as a linear feedback shift register. The intent is to make sure that different devices start at different places in the RNG cycle. Otherwise they would produce the exact same sequence.

I like to spin the RNG periodically, in a timer tick if possible. Then assuming that the need for a random number isn't correlated with the timer, you get extra randomness. A person pressing a button is always good for random timing.
