Hi

I am running the EX_WDT.C examlpe (16F877), but it doesn’t work.

The only messages is: "Hit any key to avoid a watchdog timeout".

From CCS help:Requires: Constants are defined in the devices .h file.

This file doesn’t exist.

Regards

The 'devices.h' file, for your chip, is the file 16F877.h
The '16877', is the 'device' you are using, and it's .h file contains the definitions needed.
You need both serial connections made, and pin_c7, idling high. The code waits in the 'getc', looking for a character on this line, and watchdog's out, when it is not received.

Best Wishes
