Has the WDT been opened in the zstack for cc2530?

liangliang lou

I am a new learner of the zigbee wireless networking. I have found the documents about the watchdog in the zstack,and the result was not very satisfactory ,so i want get some help form the forum.In the zstack, I only found some code about the watchdog as follow.

#ifdef WDT_IN_PM1
/* If WDT is used, this is a good place to enable it. */
WatchDogEnable( WDTIMX );
#endif

From my point of view,if i define the macro definition WDT_IN_PM1, these codes are used to enable the watchdog function in the zstack only,but where the watchdog will be cleared?Need I to write some codes to clear the watchdog in the stack?If i am,where can these codes be invoked in the zstack?

Dears,

You don't need to take care of the WDT clear inside ZStack. Just do WDT clear in your application layer.

hi YiKai Chen!

thank for all your help ! I want to enable the WDT function,so i define WDT_IN_PM1.and then I clear the WDT in the void osal_run_system( void ) function,My idea is to clear the WDT when the OSAL is scheduling,If i do it as following picture shows,whether the WDT works well in the system?

regards

Dears,

You also need to check if there is any of your application code segment that might reasonably block the system more than WDT timer. If yes, you need to add WDT clear inside.
