where directive USE_TIRTOS

Lau

Hi ,

I am looking at Wlan_station example. Under the BoardInit() function :

when is the USE_TIRTOS set or even exist ? The wlan_station is using TI_rtos_config so i believe it is running off TI RTOS , but why is it USE_TIRTOS directive not defined ???

#ifndef USE_TIRTOS
//
// Set vector table base
//
#if defined(ccs) || defined(gcc)
MAP_IntVTableBaseSet((unsigned long)&g_pfnVectors[0]);
#endif
#if defined(ewarm)
MAP_IntVTableBaseSet((unsigned long)&__vector_table);
#endif
#endif //USE_TIRTOS

That #ifndef USE_TIRTOS is if USE_TIRTOS has been defined elsewhere already. Correct me if I wrong.

It is same reason for include guards at header files. See, C include guards and one definition rule in internet.

hi Kel ,

Precisely . i believe wlan_station example is already using TI RTOS . But why is USE_TIRTOS is not set in any of the header file guard since we are using TI RTOS?

best regards

USE_TIRTOS has been set at CCS properties -> predefined symbols.
