Worked on the analogdevicesinc/no-OS repository to address a critical issue in the AD7177_2 ADC driver, focusing on embedded systems and driver development using C. Delivered a targeted bug fix by correcting a register typo and updating default register values, which improved the reliability of the ADC initialization process across supported hardware. The approach included thorough validation of the initialization path to prevent misconfiguration, ensuring stable data acquisition. The contribution was well-documented, with a clear commit history and alignment to code review standards, demonstrating a methodical workflow from issue identification through to patch delivery and future maintainability of the driver.
