ESP32 Threading

Postby Obejaris » Wed May 15, 2019 8:06 am

I am new to the ESP32 and I was wondering, how does the ESP32 handle threading? My understandig is that it runs on FreeRTOS, but I can't find any information on its thread model. When creating a new thread, how are the user threads mapped to kernel threads?

Thank you.

There are no separate kernel and user modes, so there are no separate kernel threads and user threads either.

To create a "thread", which is a "task" in FreeRTOS lingo, you use one of the API calls described here:

https://docs.espressif.com/projects/esp ... ertos.html

Either:
  • xTaskCreatePinnedToCore
  • xTaskCreate
There are examples shown there.
