Ictu()

Ictu() counts input rising edges and returns true when the preset value is reached.

bool Ictu(uint8_t counter_id, bool CU, bool RESET, int32_t PV)

Commands

Command	Arguments	Return Value	Operation
`Ictu(counter_id, CU, RESET, PV)`	`uint8_t counter_id` — Counter number. Supports `0` ~ `255`, the `uint8_t` range `bool CU` `bool RESET` `int32_t PV` — Preset value	`bool`	Counts input rising edges and returns true when the preset value is reached.

void loop() {
  bool pulse = digitalRead(0);
 
  if (Ictu(40, pulse, false, 10)) {
    digitalWrite(13, HIGH);
  }
}

The previous fixed 0~31 restriction has been removed. However, the argument type is uint8_t, so the maximum ID is 255.
If insufficient memory prevents allocation of counter state, counter commands return false or 0.
Once created, counter state is retained while the program runs.
