int timerId = 1;
void setup() {
  M5.begin();
  M5timer.enable(timerId);
}
void loop() {
  M5timer.run();
  if (M5timer.isEnabled(timerId)){
    M5.Lcd.setCursor(0, 0);
    M5.Lcd.print("Timer is enable ");
    M5.Lcd.println(millis()/1000);
  }
}
```

## isEnabled()

**Syntax:**

`boolean isEnabled(int numTimer)`

**Description:**

returns true if the specified timer is enabled
