Digital Input Filters

IdigitalRead() and the Ibounce commands reduce brief input noise and switch chatter.

Command	Arguments	Return Value	Operation
IdigitalRead(pin, samples)	Pin number, repetition count	`HIGH` or `LOW`	Reads the input several times consecutively and updates the state only when all values match. If HIGH and LOW are mixed, it retains the previous stable state.
`Ibounce(pin, ms)`	Pin number, stable time (ms)	Stabilized state	Applies a time filter in both ON and OFF directions.
`IbounceOn(pin, ms)`	Pin number, stable time (ms)	Filtered state	Delays only the OFF→ON transition.
`IbounceOff(pin, ms)`	Pin number, stable time (ms)	Filtered state	Delays only the ON→OFF transition.

void loop() {
  bool button = Ibounce(0, 30);
  digitalWrite(64, button);
}

Command Prototypes

Return Type	Command Prototype
`bool`	`Ibounce(uint8_t pin, uint32_t debounceTime)`
`bool`	`IbounceOn(uint8_t pin, uint32_t debounceTime)`
`bool`	`IbounceOff(uint8_t pin, uint32_t debounceTime)`
`bool`	`IdigitalRead(uint8_t pin, uint8_t samples)`

The Ibounce functions retain state, so keep calling them in loop(). Specify the actual pin or logical channel for your product.
