Idown() returns true only at the instant the input changes from ON to OFF.

bool Idown(uint8_t id, bool input)

const uint8_t COMMAND_INPUT = 0;
const uint8_t MOTOR_OUTPUT = 32;
 
void setup() {
  Serial.begin(115200);
}
 
void loop() {
  const bool input = IdigitalRead(COMMAND_INPUT, 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 started = Iup(0, input);  // Return true only at the instant the input changes from OFF to ON.
  const bool stopped = Idown(0, input);  // Return true only at the instant the input changes from ON to OFF.
  static bool run = false;
  Ialt(started, run);  // Toggle the specified state ON/OFF at each rising input edge.
 
  digitalWrite(MOTOR_OUTPUT, run ? HIGH : LOW);
  if (started) Serial.println(F("motor started"));
  if (stopped) Serial.println(F("command released"));
}

Using the same id for different signals may mix their previous states. Do not set the minimum and maximum of the Iscale input range to the same value.
