Sennayama developed and enhanced embedded firmware for the Space-and-Satellite-Systems-UC-Davis/IntelliSat repository, focusing on hardware integration, reliability, and automated control. Over five months, Sennayama implemented sensor drivers for I2C-based current and temperature monitoring, standardized sun sensor APIs, and expanded battery and power management features using C and embedded systems techniques. Their work included watchdog timer hardening, dual PWM channel support, and RTC alarm test coverage, all validated through targeted unit testing. By introducing features like intercom coil timing and refining build configurations, Sennayama improved system maintainability and operational predictability, demonstrating depth in device driver development and firmware testing practices.

Mar 1, 2025March 2025: IntelliSat sensor integration enhancements delivering power and environmental telemetry through improved I2C-based sensing. Implemented INA226 current sensor and TMP275 temperature sensor support with complete I2C configuration, initialization, readout, and tests, enabling reliable data collection for environmental and power metrics. Refactored TMP275 sun sensor integration to streamline initialization and data access by removing the SUN_SENSOR struct and updating sensor_tester to use sun_sensors_readVoltage, reducing complexity and maintenance overhead. Changes were implemented across SunSensors.c and TMP275.h with targeted commits, and tests were added to validate sensor readouts. Overall impact includes higher data fidelity for environmental/power telemetry, enabling proactive anomaly detection and more informed operational decisions.
