source · 
pub struct CanRx<'c, 'd, T: Instance> { /* private fields */ }
Expand description

CAN driver, receive half.

Implementations§

source§

impl<'c, 'd, T: Instance> CanRx<'c, 'd, T>

source

pub async fn read(&mut self) -> Result<Envelope, BusError>

Read a CAN frame.

If no CAN frame is in the RX buffer, this will wait until there is one.

Returns a tuple of the time the message was received and the message frame

source

pub fn try_read(&mut self) -> Result<Envelope, TryReadError>

Attempts to read a CAN frame without blocking.

Returns [Err(TryReadError::Empty)] if there are no frames in the rx queue.

source

pub async fn wait_not_empty(&mut self)

Waits while receive queue is empty.
