Overview and Purpose

• Create a highly accurate and synchronized multi-board data acquisition platform based on STM32 MCUs and Precision Time Protocol (PTP).
• Enable customers to collect and analyze time-critical, distributed data with precision and reliability across multiple STM32 boards.

Main Tasks and Technical Objectives

• Develop a solution enabling coordinated data acquisition from multiple STM32 boards with accurate calculation and compensation for network latency.
• Integrate PTP for precise time synchronization across multiple boards and ensure deterministic timestamping across the system.

Deliverables

• Provide functional example code (firmware) demonstrating multi-board acquisition, PTP synchronization, and latency compensation strategies.
• Deliver detailed documentation and support materials (design notes, API usage, integration guide, test procedures) to help the TOMAS team address advanced Ethernet synchronization and multi-board coordination questions.

Required Skills, Tools and Technologies

• Embedded C development experience using toolchains such as IAR and STM32CubeMX; familiarity with HAL drivers and relevant middleware.
• Knowledge of Ethernet networking, PTP (IEEE 1588), time synchronization techniques, and compensation algorithms for network-induced latency.

Expected Activities and Tests

• Implement and test synchronization accuracy across multiple STM32 nodes using PTP and measure end-to-end timestamp fidelity.
• Implement latency measurement and compensation methods; produce reproducible benchmark results and validation procedures.

Project Context and Environment

• PFE Book STTunis 2026 — work with the TOMAS team at STMicroelectronics (Tunis) on a customer-facing application.
