ItimerStopAll()

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().

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"));
  }
}

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.
