By software, with a quicker crystal that should certainly be fixed.
Well, maybe i'll get lazy and accept this slight error anyway
Nevertheless, I still have a question about pics.
Actually at the beginning I planned to use a 16F676, and it is still what I want to do.
I just used a spare 16F628 as among the 3 16F676's that I had up to yesterday, none were correctly recognized by the easypic4 dev board .
Today, I bought to other ones, and I'll try in the next days to program one of those.
Setting up time seems to me a reasonably necessary feature ;-) .
Up to know, I thought I would use the 6 pins from PORTA of the pic16F676 like this :
4 bits as input for the BCD to 7 segments decoder and 2 bits for one of the two
2->4 decoder of a 74LS139 , reserving PORTB to get the minutes and hour increment inputs and the alarm_triggered and set_alarm signals .
alarm_triggered and set_alarm signals should be steady and can be treated easily, but minutes and hour increment should be pulses .
So I am wondering how I could get a single interrupt from these 2 signals .
Would you have some ideas ?
