Can tasks be create/delete at run time?

Posted by Nobody/Anonymous on January 20, 2005
I am reading your FreeRTOS code. Here is a question as title. Could you tell me that all tasks have to be created at the very start? And is it easy to add counting semaphore ability? Could you give me some hints? I am new to RTOS.

Yes, tasks can be created and deleted at run time. You have to consider how memory is allocated to them though. The heap_1.c functino cannot be used.

Take a look at the file:

This is a demo app file that performs this very operation.

Also see the WEB documentation on pages:

Counting semaphores require a small mod to the existing semaphore code.
