Detailed Description

Lightweight C++ wrapper for the RTOS event-flag-group primitive.

Thread-safety: internally thread-safe; the underlying FreeRTOS event group is already MT-safe, so no extra mutex is layered on top.

Allocation: the underlying RTOS handle is created eagerly in the constructor; no heap allocation in Set / Clear / Wait.

Public surface uses modern C++ types (uint32_t, enum class WaitMode) — no OS_Ulong, OS_OR, OS_AND, OS_WAIT_FOREVER leakage. Pass UINT32_MAX to wait forever.

WaitMode

enum class WaitMode : uint8_t

strong

Selects ANY-of-bits vs ALL-of-bits semantics for Wait calls.

Enumerator
Any	Wake when any of the requested bits are set.
All	Wake only when all of the requested bits are set.
