Month: 2025-05 (ingeniamc/ingeniamotion) — Delivered a new Servo Tuning Example with PDOs that demonstrates configuring multiple servos, establishing PDO communication, capturing and plotting performance data, and orchestrating the tuning sequence. Implemented supporting components including classes for square wave generation, data plotting, and PDO callbacks, along with a central orchestrator function. The work is captured in commit 4a624c75fa6d90c54d2751a61f253212bd066492 (INGM-626: Add multiple_servo_pdo_tuning example). No major bugs fixed this month; focused on stabilizing the new example and ensuring clean integration with the repository's existing servo control and data visualization utilities. Overall impact: expands the motion control toolkit, provides a practical, reusable PDO-based servo tuning workflow, and strengthens the team's ability to validate performance through visualization. Technologies/skills: Python-based object-oriented design, Process Data Object (PDO) communication, square-wave signal generation, data plotting, PDO callback handling, and orchestration patterns for end-to-end workflows.
