Struct esp32c3_hal::twai::filter::DualStandardFilter
source · pub struct DualStandardFilter { /* private fields */ }Expand description
A filter that matches against two standard 11-bit standard ids.
The first filter part can match a packet’s id, rtr bit, and the first byte of the payload. The second filter part can match a packet’s id and rtr bit.
Warning: This is not a perfect filter. Extended ids that match the bit layout of this filter will also be accepted.

Create a filter that matches against two standard 11-bit standard ids.
The first filter part can match a packet’s id, rtr bit, and the first byte of the payload. The second filter part can match a packet’s id and rtr bit.
Examples
A filter that matches any standard id that ends with a 00 or a 11, with any rtr, and with any payload on the first filter.
const FILTER: twai::filter::DualStandardFilter = twai::filter::DualStandardFilter::new(
b"xxxxxxxxx00",
b"x",
b"xxxxxxxx",
b"xxxxxxxxx11",
b"x",

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.
