my code still gets locked out long enough to miss button presses. Hi! This tutorial is for the ESP32, not for the ESP8266. Using the portENTER_CRITICAL_ISR is the way to protect concurrent access to data in the ESP32 dual core environment. ...
LongPress: Demonstrates detecting long and short button presses. UpDown: Counts up or down, one number at a time or rapidly by holding the button down. Toggle: Demonstrates ToggleButton functionality. Constructors Button(pin, dbTime, puEnable, invert) ...
Button actions that can be detected include: State change i.e., button press and release. Short press and long press (press and hold). Multiple (short) presses; obtained via a press counter. This will count each short press that occurs within an allowed period of time (set using the lib...
