statime-embassy-net

PTP ordinary-clock runner for statime on timestamp-capable embassy-net Ethernet drivers.

This crate connects:

• statime for the PTP protocol and servo,
• embassy-net for UDP multicast transport,
• a statime::Clock implementation controlling the same hardware clock used for packet timestamps.

The network driver must provide packet timestamps through embassy-net packet metadata and asynchronous transmit timestamp polling. The optional stm32 feature provides a clock adapter for the Embassy STM32 Ethernet PTP clock. Applications using it must select their concrete embassy-stm32 chip feature.

The runner is currently a single-port UDP/IPv4 ordinary clock using E2E delay measurement. It is slave-only by default.

See src/bin/ptp.rs for a complete STM32H743 Embassy example.
