CC2530 WDT interval question

Ewing Tan

Other Parts Discussed in Thread: CC2530, Z-STACK

Has CC2530 support more than 1 sec WDT interval, i had study the WDCTL (0xC9) – Watchdog Timer Control, the max Timer interval only support 1 sec,

i has use the WatchDogEnable( 0x00 ); // 00: Clock period × 32,768 (~1 s) when running the 32-kHz XOS

then set the WDCTL.CLR to clear the timer,

WD_KICK() st( WDCTL = (0xA0 | WDCTL & 0x0F); WDCTL = (0x50 | WDCTL & 0x0F); )

but the one second WDT interval is too short,

if i want to rebot after 10 secs, how can i to set up the register?

Thanks

Hi,

1Sec is the maximum interval in case of CC2530.

You can do it manually with the help of another timer. In case you are using something like

Z-stack or some other stack which has some sort operating system, you can also use events.

Hi Igor,

Thanks for your response, but how can we do using ZStack timer (osal_set_timer etc) to trigger Event

if we need 10 sec WDT, the max interval is 1 sec, it conot allow user to trigger event than 1 sec.

Can you give more about the idea of timer..

thanks..
