Set timer/interrupt to set specific sampling frequency

Hi Rui;

Good work in all your courses.

My question is rlated to Arduino coding not Micropython.

Do you have a simpler way to use either the timer/interrupt to set  specific sampling frequency on sensor data or simply sine wave input on any ADC in the ESP32?. I already have your ESP32 course but there is n’t much on setting sampling rate.

Thanks
