Multithreading problem

[atmuc]

I have a thread that prints a counter. I also print another counter in the main loop. It works fine.

When a pin interrupt starts, my thread pauses until the interrupt handler code finished. is this normal?

is this normal?

Even though the ESP32 is dual-core, MicroPython only uses one of the cores.

Also interrupt handlers should be designed to execute fast so that they don't block other interrupts. See the docs.
