During November 2025, Semiro focused on enhancing the reliability of LED dimming in the arendst/Tasmota repository by addressing a critical integer overflow issue in the PCA9685 V2 driver. Using C++ and embedded systems expertise, Semiro corrected PWM fading step calculations and implemented value clamping to prevent overflow, resulting in smoother and more robust LED dimming transitions within the firmware. The work targeted stability under typical LED loads, with changes carefully scoped and traceable through linked commits and pull requests. This contribution demonstrated a methodical approach to firmware development, emphasizing code safety and maintainability in embedded C++ environments.
