Watch Dog Timer

[keejay]

Hi,

I'm getting a compile error when I try to clear the watch dog timer with C-Code block. It worked great in version 6. I'm using:

clear_wdt();

and get the following error when I try an compile the program in FC8:

If I disable all the clear_wdt(); then the programs compiles successfully.

It appears as though

ClrWdt();

compiles without errors

Hello,

We support the function like this in v6, v7 and v8 to remove the need for using compiler specific syntax.

Code: Select all

MX_CLEAR_WATCHDOG;

This should work on various targets which support watchdog timers, e.g. PIC, AVR etc.
