Abstract

High precision clock synchronization is the basis for all applications in network-based distributed motion control system. To solve this problem, the clock synchronization principle is analysed; the initialization process of STM32F107VC PTP(Precision Time Protocol) hardware unit is introduced, and the process of capturing time stamp by PTP hardware unit, as well as clock adjustment mechanism, is in-depth dissected. PTPd v2 clock synchronization is realized in STM32F107VC platform supported by LwIP protocol stack. The results indicate that it is able to achieve an accuracy of less than 260ns clock synchronization based on STM32F107VC PTP hardware unit.
