During November 2025, work centered on improving the stability and display reliability of the nrfconnect/sdk-zephyr repository, with a focus on embedded systems and device driver development using C. The primary contribution involved diagnosing and resolving a critical bug in the ST7789V display driver for the M5Stack Cardputer, where the x-offset parameter was corrected to align with the official M5Stack codebase. This adjustment addressed rendering anomalies affecting the leftmost column, resulting in more accurate display output and a better user experience across targeted hardware. The work demonstrated careful attention to hardware-specific details and a methodical approach to driver-level problem solving.
