Pierre-marie Ancele is an embedded systems engineer with nine years of experience designing, developing and integrating low-power microcontroller and Linux-based solutions, now focused on cockpit HMI software at Thales. He has end-to-end project experience—from customer engagement and proposal to delivery—and deep hands-on skills in RTOS and embedded frameworks (Mbed OS, Zephyr, FreeRTOS), IoT protocols (BLE, LoRaWAN, Thread, Matter) and constrained AI on microcontrollers. His open-source contributions to the widely used Arm Mbed OS—adding STM32L4 support and fixing toolchain and serial init issues—reflect a practical expertise in hardware integration and platform support. Comfortable across sensor fusion, security (TrustZone, secure elements) and energy-harvesting designs, he blends systems-level thinking with firmware-level rigor. Based in Talence, France, he brings aerospace-industry discipline and a history of shipping robust, field-ready embedded products.

Contributions summary:Pierre-marie primarily contributed to the Arm Mbed OS project by addressing issues and adding support for STM32L4 and STM32L496xG microcontrollers. Their work involved modifying GPIO usage, enabling power supplies, and adding toolchain compatibility for specific STM32L4 series MCUs. Additionally, they fixed indentation issues in a build configuration file and updated the startup scripts for the IAR and ARM Micro toolchains and fixed serial init related issues. These changes indicate a focus on hardware integration and platform-specific software development.
