STM32 FreeRTOS UART Frame Handler

A FreeRTOS-based UART communication system on NUCLEO-STM32H743ZI2 Board with frame parsing, mutex, queues, and event flags.

Interrupt-based UART RX

FreeRTOS tasks (frame parser, echo task, button task)

Mutex protection for shared buffers

Event flags for task synchronization

LED control via UART frame
