NOTICE
======

m0601-rs is licensed under the MIT License; see LICENSE.

This project contains no third-party source code. It is an independent
implementation of the DFRobot M0601 (Direct Drive Tech M0601C-111) RS485
protocol, written against public documentation and verified against the
author's own hardware captures.

Reference sources
-----------------

The protocol reference (docs/content/docs/protocol.md) records, per claim,
which of the following sources supports it and how any disagreement between
them was settled. These sources informed the documentation and were used to
cross-check test vectors; no code from them was copied into this project.

1. DFRobot FIT1042 protocol wiki
   https://wiki.dfrobot.com/fit1042/docs/23322
   Vendor documentation. Published as images; no PDF datasheet exists.

2. DDT M0601C-111 vendor sample code — tech-life-hacking/DDT_M0601C_111

On the known-answer test vectors
--------------------------------

m0601/tests/vectors.rs contains frames that also appear in sources 3 and 4.
Those two projects state no license, so nothing from them is reproduced here
as expression. The frames themselves are not expression: each byte is fully
determined by the protocol's frame layout (ID, command, big-endian payload,
padding) and by CRC-8/MAXIM, whose published check value — crc8("123456789")
== 0xA1 — anchors the implementation independently. Any correct implementation
of this protocol necessarily emits the identical bytes. They are recorded here
as a cross-check that this crate agrees with implementations known to have
driven real hardware.
