Struct esp32c3_hal::twai::filter::SingleExtendedFilter

pub struct SingleExtendedFilter { /* private fields */ }

Warning: This is not a perfect filter. Standard ids that match the bit layout of this filter will also be accepted.

Implementations

impl SingleExtendedFilter

pub const fn new(id: &[u8; 29], rtr: &[u8; 1]) -> SingleExtendedFilter

Create a filter that matches against a single 29-bit extended id.

The filter can match against the packet’s id and the rtr bit.

Examples

A filter matching any odd extended ids, with any rtr value.

const FILTER: twai::filter::SingleExtendedFilter =
    twai::filter::SingleExtendedFilter::new(b"xxxxxxxxxxxxxxxxxxxxxxxxxxxx1", b"x");

pub fn new_from_code_mask(
    id_code: ExtendedId,
    id_mask: ExtendedId,
    rtr_code: bool,
    rtr_mask: bool
) -> SingleExtendedFilter

The masks indicate which bits of the code the filter should match against. Set bits in the mask indicate that the corresponding bit in the code should match.

Trait Implementations

const FILTER_TYPE: FilterType = FilterType::Single
