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)

const uint8_t COUNTER_ID = 0;
const int32_t BOX_CAPACITY = 20;
 
void setup() {
  Serial.begin(115200);
}
 
void loop() {
  const bool itemSensor = IdigitalRead(0, 5);  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state.
  const bool resetButton = IdigitalRead(1, 5);  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state.
  const bool boxFull = Ictu(COUNTER_ID, itemSensor, resetButton, BOX_CAPACITY);  // Count rising input edges and return true when the preset is reached.
  digitalWrite(32, boxFull ? HIGH : LOW);
}

• 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.
