[majid ebru]

Hi to all

i use PIC18F2550.

when i compile my program.i see error:

 unknown pragma target: wdt pragma

how can i disable WDT??

i opened 18f2550.jal and go to line :

pragma fuse_def WDT:3 0x1 { -- Watchdog Timer Enable bit

       ENABLED = 0x1 -- WDT enabled

       CONTROL = 0x0 -- WDT disabled (control is placed on the SWDTEN bit)

       }

and change CONTROL to DISABLE .

is it true??

please help and guide me

kind regards

Hi Majid,

don't change the device file, it is useless. The chip only has the options of "enabled" and "control", no matter what names you give to the options.

It's explained in the comments you copied: If you set the pragma to "control", the bit SWDTEN controls the watchdog. Presumably that bit by default disables the watchdog, but to be sure, have a look in the device's datasheet.

Greets,
Kiste
