Ictud()

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

Ictud command operation flow

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

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.
