PROFILE

Rndas27

Rohan worked on the ISSUIUC/ISS-PCB and ISSUIUC/MIDAS-Software repositories, delivering hardware and embedded software solutions for camera and sensor subsystems over seven months. He designed and revised PCB layouts, optimized power and signal integrity, and integrated CAN bus and I2C communication for robust hardware interaction. Using C, C++, and KiCad, Rohan implemented finite state machines and hardware abstraction layers to manage real-time camera control, telemetry, and debugging feedback. His approach emphasized modularity, reliability, and maintainability, refactoring control logic and reducing global state. The work demonstrated depth in embedded systems engineering, with careful attention to manufacturability, diagnostics, and system stability.

May 1, 2025

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.
