Chapter 7

There are two options – xTaskCreate() and xTaskCreateStatic().
True. xTaskCreate() may fail if the required memory is not available.
True. vTaskStartScheduler() may fail if the required memory for the IDLE task is not available.
False. The required RAM for each task is 64 bytes plus the task stack size. The exact stack size requirements are completely dependent on your code, not FreeRTOS.
False. Tasks can be removed by calling vTaskDelete(), provided a compatible heap is used (see Chapter 15, FreeRTOS Memory Management, for details).
