Struct TwaiTx

Source 
pub struct TwaiTx<'d, Dm: DriverMode> { /* private fields */ }
Available on crate feature unstable only.
Expand description

Interface to the TWAI transmitter part.

Implementations§

Source§

impl TwaiTx<'_, Async>

Source

pub async fn transmit_async( &mut self, frame: &EspTwaiFrame, ) -> Result<(), EspTwaiError>

Transmits an EspTwaiFrame asynchronously over the TWAI bus.

Source§

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

Source

pub fn transmit(&mut self, frame: &EspTwaiFrame) -> Result<(), EspTwaiError>

Transmit a frame.

Because of how the TWAI registers are set up, we have to do some assembly of bytes. Note that these registers serve a filter configuration role when the device is in configuration mode so patching the svd files to improve this may be non-trivial.

ESP32C3 Reference Manual

NOTE: TODO: This may not work if using the self reception/self test functionality. See notes 1 and 2 in the “Frame Identifier” section of the reference manual.
