ItimerStop()

ItimerStop() stops the default or specified callback timer.

void ItimerStop()
void ItimerStop(uint8_t timerNumber)

Commands

Command	Arguments	Return Value	Operation
`ItimerStop()`	None	`void`	Stops the default or specified callback timer.

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) {
    ItimerStop();  // Stop the default callback timer after 5 s.
    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.
