In September 2025, Craig Eagleburger developed foundational documentation and system design for the Test Node Orchestrator within the embedded-purdue/slayterHIL repository. He established a clear interface architecture, selecting protobuf for data serialization and evaluating SPI, USB, and UART as physical-layer options, ultimately designating SPI for orchestrator communication. Craig’s work detailed thread layout and communication paths, providing a robust technical foundation for integration and testing. He also improved onboarding by updating setup instructions and adding new team member documentation. Using Markdown and applying skills in embedded systems and documentation, Craig’s contributions enhanced onboarding efficiency and established a stable path for future development.
