====== ItimerStopAll() ======

''ItimerStopAll()'' stops all running callback timers.

''void ItimerStopAll()''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''ItimerStopAll()'' | None | ''void'' | Stops all running callback timers. |


===== Example =====

This uses the default callback timer (Timer2). The callback changes only a flag; serial output runs in ''loop()''.

<code cpp>
void onTimer() {}

void setup() {
  Serial.begin(115200);
  if (!ItimerSet(1000, onTimer)) return;  // Configure the callback and interval first.
  ItimerStart();  // Start the configured callback timer.
}

void loop() {
  static bool stopped = false;
  if (!stopped && millis() >= 5000) {
    ItimerStopAll();  // Stop every running callback timer.
    stopped = true;
    Serial.println(F("timer stopped"));
  }
}
</code>

===== Precautions =====

  * The callback runs in an interrupt. Change only a flag there; do not call ''delay()'', ''Serial'', I2C or SPI in it.
  * The callback timer without a timer number uses Timer2. Do not use it together with ''tone()'' or PWM output that uses Timer2.
  * When specifying another hardware timer, check for conflicts with PWM, analog output and high-speed counter functions using it.
  * ''ItimerStopAll()'' stops callback hardware timers only; it does not clear ''Iton()'', ''Itof()'' or ''Itmr()'' states.
