COMPARISON OF IEEE 1588 IMPLEMENTATIONS USING THE STM32 CONNECTIVITY LINE PROCESOR
Abstract
In distributed system containing multiple clocks, precision time synchronization can by achieved using IEEE 1588 protocol. This paper presents a hardware assisted and a software implementation using the STM32 Connectivity Line (STM32C) processor. Accuracy of time synchronization depends on stability of master and slave oscillators, timestamping technique and reference clock adjustment capabilities. Allan deviation of both master and slave are measured to determine oscillator stability. Several tests using a hardware and software timestamping are made. Synchronization performance is also tested using an internal reference clock and using internal general purpose timers/counters.
