TRISC = $00
trisa = $00

PORTA=7

PORTB=0
PORTD=0
PORTC=0


FIRST:




PORTC.6=1
PORTC.2=1

Delay_ms(100)
PORTC.6=0
PORTC.2=0

PORTC.5=1
PORTC.3=1

Delay_ms(100)

PORTC.5=0
PORTC.3=0

PORTC.4=1
PORTD.0=1

Delay_ms(100)

PORTC.4=0
PORTD.0=0

Re: please small help

You have to restart watchdog in "FIRST" loop or set watchdog timer off.

can you tell me how i can do it
(reset watchdog)
 

it is restart_wdt(); at ccs c, if you look at the manual of your compiler, "ClrWdt" should be the instruction.
You can reach the manual from here:

hi...
first thanks for all
but i try to put (ClrWdt) in first my loop(after label (first)) but the problem still
and i don't know how i can use (restart_wdt())
 

I think the best way is,
find edit project in the project tab. Open it. You will see configuration bits there. Set it as OFF, you won't have to think about watchdog anymore, until you need it .
 

hi,
your codes run smoothly on my proteus 7.5


in your compiler

project -----> edit project" where you can turn off watchdog timer


to stop watchdog timer

codes:




Code: 
 asm
           clrwdt

        end  asm
