PROFILE
Carlos Pereira Atencio
Over four months, contributed to the microsoft/pxt-microbit repository by building and maintaining audio processing features and managing extension compatibility. Developed a sound level measurement extension that enabled micro:bit devices to report decibel levels, integrating it seamlessly into the gallery for educational use. Refactored audio input handling by updating the CODAL library and configuring microphone sample rates directly in C++, streamlining embedded audio workflows. Managed dependency updates and rollbacks to maintain stability, and resolved a compatibility issue by upgrading the pxt-sound-level-db extension. Work emphasized documentation, version control, and extension management, ensuring reliable integration and improved developer experience across the micro:bit platform.

Jul 1, 2025July 2025 (microsoft/pxt-microbit): Focused on CODAL dependency management to ensure stability and alignment with the latest CODAL releases. Implemented a controlled update cycle that upgraded CODAL to v0.3.2, included a rollback to v0.3.0, and performed back-to-back dependency updates without any repository code changes. This approach preserves build integrity while keeping the project in sync with upstream ecosystems. Result: more stable builds, reduced dependency risk, and prepared groundwork for easier future maintenance and downstream compatibility.
