embedded-touch

The primary goal of this crate is to provide a common interface for UI libraries like buoyant to interact with touchscreen input device drivers (e.g. FT6113).

Features

• Blocking and async interfaces
• Stylus support, including pressure, tilt, and azimuth
• Fixed-point arithmetic by default
• No heap allocation

Usage

Implement the TouchInputDevice trait for blocking operation:

use embedded_touch::{TouchInputDevice, Touch, Error};

struct MyTouchDriver { /* ... */ }

impl TouchInputDevice for MyTouchDriver {
    type Error = MyError;

    fn touches(&mut self) -> Result<impl IntoIterator<Item = Touch>, Error<Self::Error>> {
        // Read touch data from hardware
    }
}

Or implement AsyncTouchInputDevice for event-driven operation:

use embedded_touch::{AsyncTouchInputDevice, Touch, Error};

impl AsyncTouchInputDevice for MyTouchDriver {
    type Error = MyError;

    async fn touches(&mut self) -> Result<impl IntoIterator<Item = Touch>, Error<Self::Error>> {
        // Asynchronously wait for touch events
    }
}
