IctudDownState()

IctudDownState()

IctudDownState() returns the lower-limit completion state of the Up/Down counter.

bool IctudDownState(uint8_t counter_id)

Commands

Command	Arguments	Return Value	Operation
`IctudDownState(counter_id)`	`uint8_t counter_id` — Counter number. Supports `0` ~ `255`, the `uint8_t` range	`bool`	Returns the lower-limit completion state of the Up/Down counter.

Example

This example uses the P0 and P1 inputs and the P33 output on MPINO-8A4R(T)-S.

const uint8_t COUNTER_ID = 5;
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;
  Ictud(COUNTER_ID, entered, exited, false, false, RACK_CAPACITY);  // Process up and down inputs with one counter.
  const bool rackEmpty = IctudDownState(COUNTER_ID);  // Return the up/down counter's lower-limit completion state.
  digitalWrite(33, rackEmpty ? 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.
