Library not working properly when fast and multiple triggers are sent. #8
Description
Board: ESP32-EVB
GPIO: 15
DEBOUNCE_TIME: 50
The GPIO can be used as INPUT_PULLUP as I have used it before.
I am trying to implement this library in one of my projects and I am testing a PIN by putting it to LOW repeatedly and as fast as I can using my hand and a wire from GPIO 15 to GND.
This is the sketch that I've used:
#include <ezButton.h>
#define DEBOUNCE_TIME 50 // the debounce time in millisecond, increase this time if it still chatters
#define INPUT_1 15
ezButton button(INPUT_1);
void setup()
{
Serial.begin(115200);
button.setDebounceTime(DEBOUNCE_TIME); // set debounce time to 50 milliseconds
}
unsigned int foo = 0;
void loop()
{
delay(1);
button.loop(); // MUST call the loop() function first
if (button.isPressed()){
Serial.print("The button is pressed: ");
Serial.println(++foo);
}
if (button.isReleased())
Serial.println("The button is released");
}
I've added delay(1) inside void loop() to replicate one of my bigger projects, in which I need to place a delay inside the loop, otherwise the WDT gets triggered.
The problem is that it can register tens of presses or releases at once.
