The Arduino IDE typically only uses one of the fast cores. Today: We will take full advantage of the second core of the ESP32, We will test if it really increases the capacity of our microprocessor, We will also compare its dual-core speed with the speed of an Arduino UNO, We will try to synchronize tasks, even if they run on two different cores, We will also try to use the same data on both cores, These two mechanisms are mandatory if you want to use the two cores in a productive fashion, And we will not leave the Arduino IDE.
