Hi, I already tried a few libraries that I found on the internet about asyn functions. I know that the esp32 has 3 cores, but only 2 can be used. The setup() and the loop() functions uses the core #1 and in should be the core #0 free to use. The problem is that i'm not able start a function (that…

Check FreeRTOS if you would like to use multicore on the ESP32...

ESP32 - using 2nd core by default runs the RF/radio/protocols on CORE0 while the Arduino code runs on CORE1 Wait that means that the esp32 will not be able to connect to wifi? Because my esp32 is connected to wifi, and what I understand is that the wifi "runs" on core #0 [image] wobblyf: …

You can run multi-task code on a single core (usually Core 1) with FreeRTOS. You can also run tasks on Core 0, if you do it correctly.

The most useful reason to run the WiFi on core 0 is to avoid messing it up because of problems with user code. As others have said, its best to use core 1 for user code and FreeRTOS. Each core runs very fast, and FreeRTOS running on core 1 still allows the user to give different priorities to diffe…

The ESP32 has 2 processors with one processor having 2 cores. if using freeRTOS loop() should NOT have any code to run. #include "esp_system.h" //This inclusion configures the peripherals in the ESP system. #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include <driver/adc.h> #include …
