How to debug why Arduino is breaking a while loop? - c++

Question

I first added an infinite loop. Dugme is a variable for loop. But I couldn't break the loop. That’s why, when I enter the loop, I can’t exit.
void otoac()
{
long duration, distance;
while(dugme==1)
{
int distanceR = 0;
int distanceL = 0;
delay(40);
if(distance<=24)
{
moveStop();
delay(100);
moveBackward();
delay(300);
moveStop();
delay(200);
distanceR = lookRight();
delay(200);
distanceL = lookLeft();
delay(200);
if(distanceR>=distanceL)
{
turnRight();
moveStop();
}
else
{
turnLeft();
moveStop();
}
}
else
{
moveForward();
}
distance = readPing();
}
}
I have an code that when I click on case:'X' it goes in automatic mode (application). I have here the code for when I click out of 'X' that's 'x' (little x) it needs to stop but it doesn't stop. This is the code for the 'x'.
void otokapa()
{
dugme=0
motor1.setSpeed(0);
motor2.run(RELEASE); //turn motor1 off
motor2.setSpeed(0);
motor2.run(RELEASE); //turn motor2 off
}
Someone on YouTube only gave me this answer:
I added a while loop to the command, as well as a contradiction to the command, meaning, the action that the car will do when the triangle is not pressed, which is nothing.
More code:
void loop(){
if(Serial.available() > 0){
command = Serial.read();
Stop();
switch(command){
case 'F':
forward();
break;
case 'B':
back();
break;
case 'L':
left();
break;
case 'R':
right();
break;
case 'G':
onsol();
break;
case 'I':
onsag();
break;
case 'H':
arkasag();
break;
case 'J':
arkasol();
break;
case 'W':
onac();
break;
case 'w':
onkapa();
break;
case 'X':
otoac();
break;
case 'x':
otokapa();
break;
}
}
}
and dugme:
on top of all the code int dugme=1; and dugme is only in void otokapa and in otoac while(dugme==1)

Answer 1

Is this in essence what your problem looks like?
int dugme = 1; // one and only definition of this (ODR)
void otoac() {
long duration, distance;
while(dugme==1) {
}
}
void otokapa() {
dugme=0;
}
void loop(){
if(Serial.available() > 0){
command = Serial.read();
Stop();
switch(command){
case 'X':
otoac();
break;
case 'x':
otokapa();
break;
}
}
}
Possible errors violation of ODR.
if loop and otoac runs in the same thread you will never get to the serial again.
