Erik, I have been reading articles on WDT and I found very flow charts and ideas about it. Now, I know my wdt is working as a timer only, creating an interrupt if the SFR underflows. The problem I have is with the feeding sequence. 2.5 seconds after I initialize it, it creates an interrupt, I implement the feed sequence
//feed sequence
void Feed_the_PUPPY (void)
{
EA = 0;
0xFF;
KICK_THE_PUPPY
EA = 1;
}
but i do not know what is wrong with it.
I am using the EPM900 board to follow this and I see that WFEED1 = 0x0A5; WFEED2 = 0x05A; don't get set with those values after the instruction is executed...
is this normal?
Also, to verify this I notice that when the ISR is executed those registers (WFEED1 & WFEED2) are still 0x00.
