Tiny dependency-free wire-framing codec: CRC-32 length-delimited typed frames with an incremental, resynchronizing StreamParser for carrying messages over any raw byte stream (USB/CDC/socket/UART)
Multiplex several framed protocols (OTA, crash-dump, CAN bridge, app control, ...) over one byte stream: parses the stream_frame codec once and routes each frame to a per-module handler by the frame's module byte
Shared motor-controller interface for espp: the MotorAxis channel selector and the MotorController concept satisfied by the Basicmicro (serial) and Mcp266 (CANopen) drivers
