Info on hardware timers used for FreeRTOS on ESP32

[fdesvallees]

I am starting a project using a ESP-Wroom32 development board and FreeRTOS. I need to change the period of the timer that schedules FreeRTOS tasks, etc.). How do I do this? Also, how do I find out which of the ESP32 hardware timers is used for this purpose?

Thanks!

Arduino-esp32 > esp32 > FreeRTOS. At the Arduino level FreeRTOS should not be modified. What are you trying to accomplish?

At the Arduino level you have Ticker:

At ESP32 level you can access hardware timers.

Thank you, this is very helpful. I found that I can use another hardware timer for my purpose, and leave the system tick at its default value. François
