Here is the documentation for Implementing a semaphore in Zephyr.

It is very limited what one can do within an interrupt in Zephyr and using I²C within an interrupt will not work. Instead you can look at using work items (Workqueue Threads).

Another alternative is to use a semaphore. Give the semaphore in the interrupt and take it in a thread.

Hi,

I will try to reproduce to see what I can find.
