PTP4L是一个用于实现精确时间协议(PTP)的软件,它的参数如下: 1. -i interface:指定要使用的网络接口。例如:-i eth0。 2. source_clock local:指定本地时钟类型。例如:source_clock linuxphc。 3. -m mode:指定PTP的运行模式。例如:-m unicast。 4. -s:启用slave模式。 5. -f frequency:指定时钟频率。
The maximum offset the servo will correct by changing the clock frequency (phase when using nullf servo) instead of stepping the clock. This is only applied on the first update. It's specified in seconds. When set to 0.0, the servo won't step the clock on start. The default is 0.00002...
