Rohan worked on hardware and embedded software development for the ISSUIUC/ISS-PCB and ISSUIUC/MIDAS-Software repositories, focusing on camera subsystem integration, PCB design, and real-time control. He delivered multiple hardware revisions, optimizing PCB layout and signal integrity using KiCad and C/C++. Rohan implemented CAN bus and I2C communication, developed finite state machines for camera and audio control, and enhanced system reliability through modular firmware and debugging features. His approach emphasized manufacturability, modularity, and robust telemetry, reducing global state and improving testability. The work demonstrated depth in hardware-software integration, addressing real-world reliability and maintainability challenges in embedded systems.
May 2025 performance summary for ISSUIUC/MIDAS-Software: Focused on improving camera subsystem reliability and observability. Delivered the Camera Control Refactor and Live Debugging Enhancements. The camera control now uses a passed HardwareSerial object instead of a global, improving modularity and testability across platforms. Added extensive serial debugging output to monitor camera status, memory capture, and power states, enabling robust live video control and faster diagnosis of issues. No major bugs fixed in this period were recorded in the provided data; however, the change reduces surface area for bugs by removing global state. Validation was completed with commit 667ec752fa2a56f7b6691e2a699bfcbd82399064 ("Live video control works").

April 2025: Delivered visibility and telemetry improvements for the camera subsystem in ISSUIUC/MIDAS-Software. Implemented LED-based debugging indicators to reflect activation and data-read stages, providing immediate visual feedback during camera operation. Completed camera telemetry and status management with refactored control logic, memory-status reads, power-state handling, and I2C transmission, including pin reassignment and a new FSM thread for robust state management. These changes improve real-time diagnostics, reliability of camera activation sequences, and overall system health monitoring.
