How to use RTL to calculate time?

Ivan Wu

I use RTL for LPC214x, and I want to test the time used for my own code, how can I do that with RTL?
Does RTL provide some function like GetTimeCount() in VC++?

    No, it really does not.

    The "Easiest" way to do this would be add a u32 counter to the RTX_Config.c file in the os_chk_robin() function. (before the #if (OS_ROBIN == 1). increment this counter every time the os_chk_robin() function is called (which should be called on every OS Timer Tick, the rate you have set up in the RTX_Config.c File.

    u32 osTickCount;

void os_chk_robin(void)
{
    osTickCount++;
#if (OS_ROBIN == 1)
...
#endif
}

u32 getTickCount()
{
   u32 value;
   tsk_lock();
   value = osTickCount;
   tsk_unlock();
   return value;
}
