Worked on the meshtastic/firmware repository to address a critical hardware initialization issue in embedded systems using C++. Focused on stabilizing device startup by correcting the sequence of pin configuration in the SX126xInterface, ensuring that pinMode was set before any pin writes occurred. This change reduced the risk of incorrect pin states during initialization, improving hardware reliability across devices. The work required a detailed understanding of hardware interfacing and embedded firmware development, with careful attention to the order of operations at the code level. Demonstrated depth in C++ and embedded systems by delivering a targeted bug fix that enhanced device stability.
