Struct embassy_stm32::can::CanTx

pub struct CanTx<'d, T: Instance> { /* private fields */ }

CAN driver, transmit half.

Implementations

impl<'d, T: Instance> CanTx<'d, T>

pub async fn write(&mut self, frame: &Frame) -> TransmitStatus

Queues the message to be sent.

If the TX queue is full, this will wait until there is space, therefore exerting backpressure.

pub fn try_write( &mut self, frame: &Frame ) -> Result<TransmitStatus, TryWriteError>

Attempts to transmit a frame without blocking.

Returns [Err(TryWriteError::Full)] if all transmit mailboxes are full.

pub async fn flush(&self, mb: Mailbox)

Waits for a specific transmit mailbox to become empty

pub async fn flush_any(&self)

Waits until any of the transmit mailboxes become empty

pub async fn flush_all(&self)

Waits until all of the transmit mailboxes become empty

pub fn abort(&mut self, mailbox: Mailbox) -> bool

Attempts to abort the sending of a frame that is pending in a mailbox.

If there is no frame in the provided mailbox, or its transmission succeeds before it can be aborted, this function has no effect and returns false.

If there is a frame in the provided mailbox, and it is canceled successfully, this function returns true.

pub fn is_idle(&self) -> bool

Returns true if no frame is pending for transmission.

pub fn buffered<const TX_BUF_SIZE: usize>( self, txb: &'static mut TxBuf<TX_BUF_SIZE> ) -> BufferedCanTx<'d, T, TX_BUF_SIZE>

Return a buffered instance of driver. User must supply Buffers
