PROFILE

Narmistead

Nicholas Armistead developed and enhanced embedded firmware for the SunDevilRocketry/Flight-Computer-Firmware and SunDevilRocketry/mod repositories, focusing on reliability and maintainability. He centralized error handling using a unified Error_Code mechanism and introduced a shared common module to reduce code duplication and streamline onboarding. In C and Makefile, Nicholas implemented fail-fast initialization and synchronized external dependencies to prevent build issues. He also designed a camera control module with explicit error reporting via a CAMERA_STATUS enum, enabling robust GPIO-based camera management. His work demonstrated depth in embedded systems, firmware development, and hardware control, resulting in more diagnosable, maintainable, and integration-ready flight software.

Aug 1, 2025

In August 2025, delivered a focused enhancement to the SunDevilRocketry/mod camera module: introduced a CAMERA_STATUS enum for explicit error reporting and refined set_camera_state to distinguish invalid selections from success, significantly improving reliability and diagnosability of camera operations.

Jul 1, 2025

July 2025 performance highlights for SunDevilRocketry/mod: Delivered a Camera Control Module for the Flight Computer, enabling GPIO-based turn-on/off control for main and drogue cameras. The work includes header files and type definitions to support hardware abstraction and future integrations. Two commits were made: b23ea165f61fa7591e7eae494022aaceae555fde (New camera module) and 12e7ebf5bfb170fac4bc35162abccfb2f742872f (Clean up camera module). Major bugs fixed: none reported this month. Impact: reduces wiring complexity, improves reliability of camera control during flight, and creates a foundation for automated camera sequencing and data capture. Technologies/skills demonstrated: embedded GPIO control, C module architecture, hardware-software integration, code cleanup/refactor, header/type definition management.

June 2025 delivered core reliability and maintainability improvements across SunDevilRocketry firmware and tooling, focusing on centralized error handling, modular common utilities, and synchronized dependencies. Key outcomes include: unified error handling via central Error_Code and fail-fast initialization across firmware components (app, canard/rev2, data-logger/rev2, dual-deploy, terminal); integration of a shared common module to enable consistent behavior and reduce duplication; external dependency synchronization by updating submodules to newer commits to mitigate drift and build issues; in mod, introduction of unified error handling and delay abstraction with a comprehensive ERROR_CODE enum and wrapper functions for HAL_Delay and Error_Handler, with naming consistency improvements. These changes improve system reliability, reduce debugging time, and streamline onboarding for new firmware modules, while demonstrating proficiency in embedded C, HAL, build tooling, and version control practices.
