Returns the number of milliseconds since the LaunchPad board began running the current program. This number will overflow (go back to zero), after approximately 50 days.
None
Number of milliseconds since the program started (unsigned long)
unsigned long time;
void setup(){
Serial.begin(9600);
}
void loop(){
Serial.print("Time: ");
time = millis();
//prints time since program started
Serial.println(time);
// wait a second so as not to send massive amounts of data
delay(1000);
}
Note that the parameter for millis is an unsigned long, errors may be generated if a programmer tries to do math with other datatypes such as ints.
