# `ExDlt645.Framer`
[🔗](https://github.com/Ultraluv/ex_dlt645/blob/v0.1.0/lib/ex_dlt645/framer.ex#L1)

`Circuits.UART.Framing` implementation for DL/T 645-2007 streams.

Accumulates bytes, identifies `0xFE` preambles and `0x68` start delimiters,
verifies the secondary delimiter `0x68`, deduces the expected frame length from
the length field `L`, validates the modulo-256 checksum and `0x16` end delimiter,
and resynchronizes byte-by-byte in the presence of noise.
