I am just starting to use FreeRTOS. I went through the demos and got a basic understanding. I would like to implement a task which waits for an event, for example the presence of an item in a queue, but without polling the queue every x ticks. In other words, I want the task to activate on a specific event. Is this possible with FreeRTOS or do I have to use vTaskDelay and check the event every x ticks?
