I am researching about different IoT development boards and found that espressif uses IDF framework. When looked at the source code it uses FreeRTOS libraries. I have Arduino Uno and i wanted to use FreeRTOS for programming Arduino Uno. After search i found that FreeRTOS has multiple libraries that supports different micro controllers. Arduino Uno has ATMega328P and FreeRTOS has libraries for ATMega328P (link below)
I also found that libraries created for Arduino family of boards (link below) https://www.arduino.cc/reference/en/libraries/freertos/
I just wanted to what is the difference between these two libraries?
