Vladislav Pejic developed and enhanced sensor driver functionality in the kholia/zephyr repository, focusing on robust RTIO streaming support for ADXL367 accelerometers. He implemented asynchronous data reading using FIFO triggers and enabled flexible FIFO channel configurations for XYZ and temperature data, leveraging C and Zephyr RTOS. Addressing data integrity, Vladislav fixed Q31 data conversion issues in RTIO streaming for ADXL372 and ADXL362 sensors, ensuring accurate temperature and acceleration reporting. His work demonstrated depth in driver development, embedded systems, and sensor integration, delivering both new features and critical bug fixes that improved streaming reliability and data accuracy across multiple sensor models.
