Why Prop C program doses not run for ever?

msiriwardena · 2018-05-21 20:50

I am trying out Prop c programing.
T wrote the attached program with "While(1)" and is suppose to run for ever,

but runs only for 1min and 15 sec, the program shuts down. The program is running in a Propeller Activity board WX.
This is repeatable.

I would like a guru to explain this issue.

Thank you.

P.S : the zip file is attached

Move the serial_open call outside of the loop and it will probably work better. That may be allocating memory on each call and eventually running out.

int main()                                    // main function
{
  lcd = serial_open(12, 12, 0, 9600);
  while(1)                                    // Repeat indefinitely
  {
    int cmDist = ping_cm(15);                 // Get cm distance from Ping)))
    print("cmDist = %d\n", cmDist);           // Display distance
    pause(20);                               // Wait 1/5 second
    
    writeChar(lcd, ON);
    writeChar(lcd, CLR);
    writeChar(lcd, 17);
    pause(10);
    dprint(lcd,"The distance is = %d"), cmDist;
    pause(200);
  }
}
