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);
}
//----------------------------------------
}
}
