Thank you everyone for all the suggestions. I used the hardware timer group function similar to this tutorial to implement the specific sampling rate that I need: https://techtutorialsx.com/2017/10/07/esp32-arduino-timer-interrupts/ I also found and tried a sample code based on the comment of ESP_ig...

Thank you for this, ESP_Dazz! I will update this post once I am able to do it based on your suggestion.

Hello! I'm currently using the ADC analog input of the ESP32 to get sensor readings. However, I'm confused in setting up the sampling rate of the ADC reading. Can I ask for some guide or tips to set the sampling frequency? My goal is to get 6000 samples per second from the ADC input. Thanks!
