From register to GUI

IOWeaver plots what your device says. RockFace debugs the firmware that says it. WireWeaver keeps both sides speaking the same API.

API

#[ww_trait]
#[claim(exclusive)]
pub trait Uart {
    #[counted]
    stream!(rx: RxChunk<'i>);

    #[credit]
    sink!(tx: MaxLen<RefVec<'i, u8>, UART_TX_MAX>);

    fn configure(config: UartConfig) -> Result<UartConfig, UartError<'i>>;
    fn send_break(duration: Second) -> Result<(), UartError<'i>>;
}
