I tried this code, but doesn’t work. For some reason i can’t decrease period time between samples to less than 0,667 [ms], even when i change the middle parameter in timerAlarmWrite. In this case i putted in 0,5 [ms]. #include <Arduino.h> #include "esp_timer.h" volatile int interruptCounter; int …

Error to sampling a signal with a period lesse than 0,667 [ms]
