STMicroelectronics AN3411 IEEE 1588 PTP Application Note for STM32F107

About this manual

This document presents a demonstration package for implementing the IEEE 1588-2002 and IEEE 1588-2008 Precision Time Protocol (PTP) on the STM32F107 connectivity line microcontroller. It utilizes the MCU's built-in hardware time stamping unit to achieve sub-microsecond synchronization precision, which is superior to software-only solutions.

The application note details the integration of the PTP daemon (PTPd) with the lwIP TCP/IP stack. It provides specific instructions for setting up the STM32F107 Ethernet MAC controller's time stamping unit, configuring correction methods, and porting the software stacks. The guide includes examples using evaluation boards such as the STEVAL-PCC010V1 and STM3210C-EVAL.
