Hi, I need to configure the WDT timeout to 30 seconds, it is possible?
How I can do this, I am using the PIC18F452, 20Mhz |

The maximum WDT timeout is 2.3 seconds (nominal) with the 18F452.
If you upgrade to the improved version of that PIC, which is the 18F4520,
then you can go up to 131 seconds timeout for the WDT. |

Or you could add a 74123,R,C for your own hardware WDT.It'll take a couple of pins but you program it for whatever time you want. |
