ClickButton library long pressed issue

Troubleshooting
1

Hi,

I am having a problem with the long pressed function in the ClickButton library.

Test code:

#include "application.h"
#include "clickButton.h"
#include "SPI.h"

SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC);

// BUTTON define
#define EXTPIN D7
#define RUNPIN D3

// button define
ClickButton exitButton(EXTPIN, LOW, CLICKBTN_PULLUP);
ClickButton runButton(RUNPIN, LOW, CLICKBTN_PULLUP);

// Button results
int funcRunButtn = 0;

// setup() runs once, when the device is first turned on.
void setup() {
  // Put initialization like pinMode and begin functions here.
  // init serial
   Serial.begin(9600);

   WiFi.on();
   Particle.connect();

   pinMode(EXTPIN, INPUT);
   pinMode(RUNPIN, INPUT);

   // Setup button timers (all in milliseconds / ms)
     // (These are default if not set, but changeable for convenience)
     exitButton.debounceTime   = 20;   // Debounce timer in ms
     exitButton.multiclickTime = 250;  // Time limit for multi clicks
     exitButton.longClickTime  = 1000; // time until "held-down clicks" register

     runButton.debounceTime   = 20;   // Debounce timer in ms
     runButton.multiclickTime = 250;  // Time limit for multi clicks
     runButton.longClickTime  = 1000; // time until "held-down clicks" register
}

// loop() runs over and over again, as quickly as it can execute.
void loop() {
  // The core of your code will likely live here.

  // Update button state
      runButton.Update();

      // Save click codes in LEDfunction, as click codes are reset at next Update()
      if(runButton.clicks != 0) funcRunButtn = runButton.clicks;
      if(funcRunButtn == 1)
      {
        Serial.println("Run BUTTON SINGLE click");
        LngButtonTest();
      }

    funcRunButtn = 0;
    delay(5);
}

void LngButtonTest()
{

  bool isTestDone = false;
  int fExtButtn = 0;
  
  Serial.println("");
  Serial.println("Enter Long Button Test Function");
  Serial.println("");

  while (!isTestDone)
     {
       exitButton.Update();
       if(exitButton.clicks != 0)
       {
         fExtButtn = exitButton.clicks;
       }

       if(fExtButtn == 1)
       {
         Serial.println("EXIT BUTTON SINGLE click");
       }
       if(fExtButtn == -1)
       {
         Serial.println("EXIT BUTTON SINGLE LONG click");
         isTestDone = true;
       }

      fExtButtn = 0;
      delay(5);
    }


}

Output:

Opening serial monitor for com port: "COM3"
Run BUTTON SINGLE click                     <---  I pressed  the run button

Enter Long Button Test Function

EXIT BUTTON SINGLE LONG click        <---- I pressed the exit button long pressed
Run BUTTON SINGLE click                    <---- I pressed the run button again

Enter Long Button Test Function

EXIT BUTTON SINGLE LONG click    <<<< problem, automatic exit without pressed exit long button

It look like exitButton.Update(); still get the previous value (-1) in this case, button did not get reset even no pressed action. If I press the run button the third time, the problem does not happen.

Any one have encounter this before or any pointers? Thanks

Problem solved:

When I put a check loop until !-1 in front of while(!isTestDone), the problem when away. I believe I am triggering the exitbutton to soon since there is a debounce timer. When I trigger the button before the timer runs out that when I see the automatic execution.
