-Developed a round-robin scheduler and queue functions in C to manage tasks and timers based on a specified periodicity and system monitoring tick. These functions were implemented using configuration and control data structures, as well as macros, in compliance with the AUTOSAR standard. Additionally, I applied unit testing with Ceedling and documented the code using Doxygen.-Configured various peripherals of the NXP S32K144 microcontroller using its MCAL drivers with EB Tresos to enable their corresponding AUTOSAR APIs. The primary MCAL drivers utilized included MCU, Platform, Port, Dio, Gpt, Adc, Pwm, and Spi.-Implemented a double-click state machine for three buttons using round-robin scheduler functions and I/O hardware abstractions with MCAL driver APIs, as well as configuration and control data structures. Based on the state of each button, the system performs specific actions such as toggling LEDs, activating a buzzer at a specified frequency, or reading the analog value from a potentiometer.-Engineered the Det error reporting function in the AUTOSAR Det module, utilizing pointers and hash tables to report errors related to MCAL driver configurations or API calls.-Debugged the code execution and analyzed the MCU configuration and status registers using OZONE.
