Hi,
I’m looking for a good way of seeding the random number generator on a Xiao. On other Arduino based projects I use the Entropy code written by Walter Anderson. This fails to compile for the Xiao with the error:
Entropy.cpp:92:3: error: ‘ATOMIC_BLOCK’ was not declared in this scope
ATOMIC_BLOCK(ATOMIC_RESTORESTATE)
Other suggestions are to perform an analogue read on a floating analogue pin but I’m using all the pins on the Xiao so that’s a little difficult!
I was wondering if there is an easy fix for the above error, or a better way of seeding the random number generator?
Many thanks
Martin
