micros()

Returns the number of microseconds since the Maple board began running the current program. This number will overflow (go back to zero), after approximately 70 minutes.

Note

There are 1,000 microseconds in a millisecond, and 1,000,000 microseconds in a second.

Library Documentation

uint32 micros(void)

Returns time (in microseconds) since the beginning of program execution.

On overflow, restarts at 0.

See:millis()

Example

unsigned int time;

void setup() {
}

void loop() {
  SerialUSB.print("Time: ");
  time = micros();
  // prints time since program started
  SerialUSB.println(time);
  // wait a second so as not to send massive amounts of data
  delay(1000);
}
