CCS Bootloader and WatchDog
PostPosted: Sun Jun 18, 2006 12:34 pm     Reply with quote
Hi,

I need to have WatchDog in my program and for this I activate this fuse in the CCS bootloader and my program, this is the fuse

Code:
#include <18F4620.h>
#device *=16
#fuses   H4, WDT4096, PROTECT, NOLVP, PUT
#use delay(clock=40000000, RESTART_WDT)
#use rs232(baud=115200, xmit=PIN_C6, rcv=PIN_C7, RESTART_WDT)
#opt 10


and in the main put:

Code:
setup_wdt( WDT_ON );


But the watchdog not work, anybody know where is the problem????

Thank you very much!!

Best Regards,
asmallri

You have reset WDT enabled in #use delay. This means whenever time functions get used (such as delay_ms) or whenever you send a character the WDT is reset. If you program "crashes" in such a manner that it reamins in a loop that uses any delay functions the WDT will never time out.

Because you have used such a large WDT valaue (4096) the easiest solution is to remove the reset wdt from the #use delay statement.
