[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [December 2009 Threads] Best way to block a task?Posted by raedbenz on December 7, 2009 HI,, I need to run a task after acertain event occurs (e.g. button push).. so what is more efficient with the minimum cpu overheads and more reliable, to use **vTaskSuspend** from the first call to of the task, or a semaphore with max delay. ? thanks
RE: Best way to block a task?Posted by Dave on December 7, 2009 Use a binary or counting semaphore with max delay. If you set INCLUDE_vTaskSuspend to 1 in FreeRTOSConfig.h then max delay will be an indefinite delay.
Do not use vTaskSuspend() for event processing. It does not latch events so it is easy to miss them.
