Ictud()

Ictud() handles increment and decrement inputs in one counter.

bool Ictud(uint8_t counter_id, bool CU, bool CD, bool RESET, bool LOAD, int32_t PV)

Commands

Command	Arguments	Return Value	Operation
`Ictud(counter_id, CU, CD, RESET, LOAD, PV)`	`uint8_t counter_id` — Counter number. Supports `0` ~ `255`, the `uint8_t` range `bool CU` `bool CD` `bool RESET` `bool LOAD` `int32_t PV` — Preset value	`bool`	Handles increment and decrement inputs in one counter.

Example

This example uses the P0 through P3 inputs and the P32 output on MPINO-8A4R(T)-S.

const uint8_t COUNTER_ID = 2;
const int32_t RACK_CAPACITY = 100;
 
void setup() {
  Serial.begin(115200);
}
 
void loop() {
  const bool entered = digitalRead(0) == HIGH;
  const bool exited = digitalRead(1) == HIGH;
  const bool reset = digitalRead(2) == HIGH;
  const bool preset = digitalRead(3) == HIGH;
  const bool full = Ictud(COUNTER_ID, entered, exited, reset, preset, RACK_CAPACITY);  // Process up and down inputs with one counter.
  digitalWrite(32, full ? HIGH : LOW);
}

Precautions

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.
