Expand description

Interface for interacting with Acceptance Filters.

The Acceptance Filter is a programmable message filtering unit that allows the TWAI controller to accept or reject a received message based on the message’s ID field.

Only accepted messages will be stored in the Receive FIFO.

The Acceptance Filter’s registers can be programmed to specify a single filter, or two separate filters (dual filter mode).

Required Associated Constants§

Source

const FILTER_TYPE: FilterType

The type of the filter.

Required Methods§

Source

fn to_registers(&self) -> [u8; 8]

Get the register level representation of the filter.

Provided Methods§

Source

fn filter_type(&self) -> FilterType

Returns filter type.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
