I really beginner with freeROTS. my question is: why, after this code,

ret\_val = xTaskCreate (vMMI\_Menu, “MMI\_Menu”, configMINIMAL\_STACK\_SIZE, NULL, \  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; tskIDLE\_PRIORITY+1, NULL);  
call the main code&nbsp; this&nbsp; function

signed portBASE\_TYPE xTaskCreate( pdTASK\_CODE pvTaskCode, const signed portCHAR \* const pcName, unsigned  
portSHORT usStackDepth, void \*pvParameters, unsigned portBASE\_TYPE uxPriority, xTaskHandle \*pxCreatedTask )  
{  
signed portBASE\_TYPE xReturn;  
tskTCB \* pxNewTCB;  
.

Thank you in advance

Sorry - I don’t understand your question.&nbsp; Can you re-phrase it?

Regards.

hi richardbarry ,

I hope to get my idee.

when I have the code Main of simulation software studio 4. Exact in this line 'ret\_val = xTaskCreate (vMMI\_Menu, “MMI\_Menu”, configMINIMAL\_STACK\_SIZE, NULL, tskIDLE\_PRIORITY+1, NULL) ‘’ call this&nbsp; instead of calling the function ‘‘signed portBASE\_TYPE xTaskCreate( pdTASK\_CODE pvTaskCode, const signed portCHAR \* const pcName, unsigned&nbsp; portSHORT usStackDepth, void \*pvParameters, unsigned portBASE\_TYPE uxPriority, xTaskHandle \*pxCreatedTask )’’. I am tried to find the function ‘‘vMMI\_Menu’’ but i dont have it in my code .why the simulation he desen’t give me error or why he go in the ander function.&nbsp;

Thank you in advance

I think you are saying that you are using xTaskCreate() to create a task that is defined by the function vMMI\_Menu - but vMMI\_Menu does not appear anywhere in your project so you don’t understand how it can link.

I would agree with you, if vMMI\_Menu does not exist then the code cannot link.&nbsp; Maybe it isn’t linking?&nbsp; Or maybe vMMI\_Menu is #defined to something else?&nbsp; In any case I have looked through the FreeRTOS code and cannot see that the name vMMI\_Menu appears anywhere so I’m guessing it is a function you have defined yourself.

Regards.
