Itof()

Itof() (Off Delay Timer) returns false after a specified time has elapsed since the condition turned OFF.

Itof command operation flow

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

Commands

Command Arguments Return Value Operation
Itof(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 (Off Delay Timer) returns false after a specified time has elapsed since the condition turned OFF.

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. The output stays on for 2 s after the input goes off. 

const uint8_t INPUT_PIN = 0;
const uint8_t OUTPUT_PIN = 32;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_PIN) == HIGH;
  const bool outputOn = Itof(0, inputOn, 2000);  // Keep returning true for 2 s after the input turns off.
  digitalWrite(OUTPUT_PIN, outputOn ? HIGH : LOW);
}
