Functions
template<typename TaskType >
auto	create_task (TaskType &task, char const *const name, uint16_t stack, UBaseType_t prio=0, TaskHandle_t *const handle=nullptr) -> void
	Create a rtos task. TaskType needs a void run() public method.
auto	delete_task (TaskHandle_t task) -> void
	Delete a rtos task. If handle is nullptr, the current task will be deleted.
template<typename TaskType >
auto	rtos_task (void *task) -> void
	Wrapper for an rtos task struct. Calls the run() member.
auto	sleep_for (etl::uint32_t ticks) -> void
	Delay a task for a given number of ticks. The actual time that the task remains blocked depends on the tick rate.
auto	sleep_until (etl::uint32_t &prev, etl::uint32_t increment) -> void
	Delay a task until a specified time. This function can be used by periodic tasks to ensure a constant execution frequency.
auto	start_scheduler () -> void
	Start the RTOS, this function will never return and will schedule the tasks.
auto	yield () -> void
	Request a context switch to another task.
