I am trying to setup multitasking in my app.
One of the instructions to set this up was to use
OSInit(); and OSStart(); When I tried to compile with this I encountered an
error telling me that the the parameter list was incomplete, that
it should be OSInit( void *idle_task_stk_top, void *idle_task_stk_bot, BYTE maxtasks );
Does anyone know why there is discrepancy and if they know how to
create more than one task beside a UserMain and one other separate task?

Use the following declarations from file ucos.h:

#define OSSimpleTaskCreate(x,p) { static DWORD func_##x_Stk[USER_TASK_STK_SIZE] __attribute__( ( aligned( 4 ) ) ); OSTaskCreate(x,NULL,(void *)&func_##x_Stk[USER_TASK_STK_SIZE],(void*)func_##x_Stk,p); }
#define OSSimpleTaskCreatewName(x,p,n) { static DWORD func_##x_Stk[USER_TASK_STK_SIZE] __attribute__( ( aligned( 4 ) ) ); OSTaskCreatewName(x,NULL,(void *)&func_##x_Stk[USER_TASK_STK_SIZE],(void*)func_##x_Stk,p,n); }

Thank you! I actually figured out what my real problem was.
I wasn't using a separate stack for the second task I was creating,
I was using the same stack for both tasks. But thank you for that
speedy and no doubt useful response.

navydev,

I don't think you are supposed to be calling those functions directly. Rather, you should be using the wrapper functions like in the previous post. Otherwise I think you are going to miss something and possibly get erratic behavior at some point in the future. Just my opinion.
