Simple PIC based timer needed, any advice appreciated.

[amgen]

the devices with the 8 mhz int osc are about 1%, (12f283 for example) pretty good timing.
i would blink an led at 1 sec and use the 1 second as a time base. the led just shows that your ckt is doing something.
there are 86400 seconds/day but a var word is only 16 bit - max 65535 count so use 2 second count inc up to 43200.

start:
while count < 43200
high led
pause 1000
low led
pause 1000
count=count+1
end while
outputRSTpin=1
pause 2000
outputRSTpin=0
count=0
goto start
