Teensy 4.1 Problems

[jimmie11]

I have a relatively large program running on a Teensy 4.1. The program has a web server, a TCP server and interfaces to two sensors.

The system is connected to a traffic loop. When a car comes, the loop is triggered and the teensy senses a "dry contact". I then start reading from the connected sensors. I am not using a pull-up resistor with the loop as I am relying on the internal one as shown in the attached code.

After about 800 loop activations, my code stops sensing the loop. I am sure that my code did not crash because I can still connect to the TCP server and can display data from the Teensy on a web browser. So the program is still running but is not sensing any loop closures. When I restart the program by connecting to its web server, everything starts working again.

I would appreciate any help regarding what may be causing this problem.

The code is below:

#include <Bounce2.h>
        Bounce myLoop1 = Bounce();
        Bounce myLoop2 = Bounce();
        int debounce_interval_time = 7;

        #define loop1 32    
        #define loop2 33

        volatile unsigned long   lastLoopTime;
        volatile bool leddarCapturing = false;

        bool loopInterrupt = false;
        long loopInterruptTime;
        long numLoopInterrupt = 0;

        void setup(void)
        {
          setUpPins();
          BounceInterrupt();

        }

        void loop()
        {
          //---------------------------------------------------------------------------------
            myLoop1.update();
            myLoop2.update();

            if (myLoop1.read() == 0) activateLoop1New();
          //---------------------------------------------------------------------------------
        }

        void setUpPins()
        {
          //------------------------------------------------------------------------------
          pinMode(loop1, INPUT_PULLUP);
          pinMode(loop2, INPUT_PULLUP);
          //------------------------------------------------------------------------------
          delay(500);
        }

        void BounceInterrupt()
        {
          //------------------------------------------------------------------------------
            myLoop1.attach(loop1);
            myLoop1.interval(debounce_interval_time);

            myLoop2.attach(loop2);
            myLoop2.interval(debounce_interval_time);
          //------------------------------------------------------------------------------
        }

        void activateLoop1New()
        {
          if ((millis() - lastLoopTime) > 120)  //Guard against multiple loop triggers within a short time
          {
            //----------------------------------------
            lastLoopTime = millis();
            if (! Capturing) 
            {
              digitalWrite(yellowPin, HIGH);
            }
            if (Capturing)
            {
              loopInterrupt = true;    
              loopInterruptTime = millis();
              numLoopInterrupt = numLoopInterrupt + 1;
              digitalWrite(yellowPin, LOW);
            }
            //----------------------------------------
          }
        }
