Next step on getting an NTP server running on the ch32v307 dev board is verifying the local clock. This is part of a series on the ch32v307 dev board There's two local clocks to consider: the PTP hardware timestamp clock, and the PPS input capture clock. I'll focus just on

The CH32V307 microcontroller caught my interest because it has both IEEE 1588 timer hardware and the capability to connect via gigabit ethernet. If I ported my NTP server software to it, this would lower the round trip latency (excluding processing time) by around 10x. It's a RISC-V based microcontroller, running
