[Vex C++]How to Multitask

VEX V5 Technical Support

pretty close.

example using vex::task class.


vex::brain Brain;

int myTask() {
    int count = 0;
  
    while(1) {
      Brain.Screen.printAt( 10, 60, "I am the other task %d", count++ );
      
      // don't hog the cpu :)
      vex::task::sleep( 25 );
    }
  
    return(0);
}

int main() {
    int count = 0;

    // this is similar to startTask
    vex::task t( myTask );
  
    while(1) {
      Brain.Screen.printAt( 10, 30, "Hello from main %d", count++ );

      // Allow other tasks to run
      vex::task::sleep(10);
    }
}

example using vex::thread class


vex::brain Brain;

int myThread() {
    int count = 0;
  
    while(1) {
      Brain.Screen.printAt( 10, 60, "I am the other task %d", count++ );
      
      // don't hog the cpu :)
      vex::this_thread::sleep_for( 25 );
    }
  
    return(0);
}

int main() {
    int count = 0;

    // this is similar to startTask
    vex::thread t( myThread );
  
    while(1) {
      Brain.Screen.printAt( 10, 30, "Hello from main %d", count++ );

      // Allow other tasks to run
      vex::this_thread::sleep_for(10);
    }
}

So why do we have two different versions of the same thing.

vex::task has methods that will be familiar to ROBOTC users. methods such as setPriority and stop.
vex::thread has methods that will be familiar to users of the C++ standard library. methods such as join.
