Itmon()

Itmon() (Monostable Timer) outputs a pulse whose duration is not extended by another input during operation.

bool Itmon(uint8_t timer_id, bool state, unsigned long delayTime)

Commands

Command	Arguments	Return Value	Operation
`Itmon(timer_id, state, delayTime)`	`uint8_t timer_id` — Timer number. Supports `0` ~ `255` `bool state` — Timer input state `unsigned long delayTime` — Preset time in ms	`bool`	(Monostable Timer) outputs a pulse whose duration is not extended by another input during operation.

Example

This example selects MPINO-8A4R(T)-S and uses input P0 and output P32. Call the command on every pass through loop() without blocking it. A rising input turns the output on for 1 s; another rising edge during the pulse does not extend it.

const uint8_t INPUT_PIN = 0;
const uint8_t OUTPUT_PIN = 32;
 
void setup() {
  pinMode(INPUT_PIN, INPUT);
  pinMode(OUTPUT_PIN, OUTPUT);
}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_PIN) == HIGH;
  const bool outputOn = Itmon(0, inputOn, 1000);  // Make a 1 s pulse on a rising edge; ignore retriggers while active.
  digitalWrite(OUTPUT_PIN, outputOn ? HIGH : LOW);
}

Precautions

Call the timer command repeatedly in loop() so elapsed time and OFF input are processed.
Do not share a timer_id between different timer operations; use a separate ID for each.
