FDCAN Tx only Instance

Implementations

impl<'c, 'd> CanTx<'d>

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

Queues the message to be sent but exerts backpressure. If a lower-priority frame is dropped from the mailbox, it is returned. If no lower-priority frames can be replaced, this call asynchronously waits for a frame to be successfully transmitted, then tries again.

pub fn blocking_write(&mut self, frame: &Frame) -> Option<Frame>

Blocking write frame.

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

pub async fn write_fd(&mut self, frame: &FdFrame) -> Option<FdFrame>

Queues the message to be sent but exerts backpressure. If a lower-priority frame is dropped from the mailbox, it is returned. If no lower-priority frames can be replaced, this call asynchronously waits for a frame to be successfully transmitted, then tries again.

pub fn blocking_write_fd(&mut self, frame: &FdFrame) -> Option<FdFrame>

Blocking write FD frame.

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

pub async fn write_marked(&mut self, frame: &Frame, marker: u8) -> Option<Frame>

Like Self::write, but stores a TX event carrying marker once the frame has been sent. Read it back with Self::dequeue_tx_event.

pub async fn write_fd_marked( &mut self, frame: &FdFrame, marker: u8, ) -> Option<FdFrame>

Like Self::write_fd, but stores a TX event carrying marker once the frame has been sent. Read it back with Self::dequeue_tx_event.

pub fn dequeue_tx_event(&mut self) -> Option<(Id, u8, Timestamp)>

Pops the oldest TX event: the frame id, its marker and the start-of-frame timestamp.
