unflappable
A batteries-included embedded-hal InputPin
debouncer.
Quickstart
Add the following to your Cargo.toml
:
[dependencies]
unflappable = "0.2"
Create an uninitialized Debouncer
in static storage.
use unflappable::{debouncer_uninit, Debouncer, default::ActiveLow};
static DEBOUNCER: Debouncer<PinType, ActiveLow> = debouncer_uninit!();
Initialize the Debouncer
with your input pin, returning the
Debounced
pin. Use this pin just as you would any other
InputPin
, such as passing ownership to another abstraction.
let debounced_pin = unsafe { DEBOUNCER.init(input_pin) }?;
Regularly poll the Debouncer
, perhaps in an interrupt service routine.
unsafe {
DEBOUNCER.poll()?;
}
