TwaiRx

esp_hal::twai

Struct TwaiRx 

Source 
pub struct TwaiRx<'d, Dm: DriverMode> { /* private fields */ }
Expand description

Interface to the TWAI receiver part.

Implementations§

Source§

impl TwaiRx<'_, Async>

Source

pub async fn receive_async(&mut self) -> Result<EspTwaiFrame, EspTwaiError>

Receives an EspTwaiFrame asynchronously over the TWAI bus.

Source§

impl<Dm> TwaiRx<'_, Dm>
where Dm: DriverMode,

Source

pub fn error_counts(&self) -> ErrorCounts

Available on crate feature unstable only.

What the controller has reported since the driver was started (see ErrorCounts)

§Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Source

pub fn receive(&mut self) -> Result<EspTwaiFrame, EspTwaiError>

Receives a frame.
