Contributed to the PurdueElectricRacing/firmware repository by developing and refining core data acquisition (DAQ) features over a three-month period. Delivered GPS-based time synchronization to enhance RTC accuracy for data logging, and redesigned the DAQ subsystem using C and DMA management to implement a lockless single-producer/multiple-consumer architecture for efficient CAN data handling, SD logging, and UDP streaming. Removed legacy TCP code and enabled 4-bit SDIO transfers to improve throughput and reduce CPU overhead. Focused on maintainability by refactoring the DAQ hub and cleaning up unused CAN signal definitions, laying a foundation for future enhancements in embedded real-time systems.

Feb 1, 2026February 2026: Delivered a major DAQ subsystem redesign for PurdueElectricRacing/firmware, implementing a lockless single-producer/multiple-consumer (SPMC) architecture to optimize CAN data handling, SD logging, and Ethernet UDP streaming. Removed legacy TCP code to streamline the data path, and enabled 4-bit SDIO transfers to improve throughput. The SD logging thread now blocks on DMA writes to maximize data transfer efficiency, with the SD logging path thoroughly tested. Business value includes higher telemetry bandwidth, more reliable streaming to SD/UDP endpoints, and reduced CPU overhead. Commit 40e15a7d2ec1132e1ba8fe6778aba86cf56dc2ac (DAQ Redesign with Lockless SPMC) with co-authored-by Irving Wang.
