Mike H. developed oscillator-based timing and synchronization enhancements for the ISS-PCB repository, focusing on improving timing accuracy and system reliability within the MCU and decoder subsystems. Leveraging his expertise in PCB design, circuit design, and embedded systems, he integrated new oscillator components to reduce timing drift and enable more predictable circuit operation. The work involved hardware-software integration using Kicad, resulting in a more stable foundation for downstream modules and performance-dependent features. Over the course of the month, Mike concentrated on feature delivery and hardware timing optimization, demonstrating depth in embedded hardware design and a methodical approach to subsystem reliability.
