event triggering from ds1302 time

Archiver

I'm trying to read a time value from the DS1302 chip and then
evaluate it against an "alarm time." I'm able to set the time and
display it in the debug window, but I can't yet capture the value to
compare it to my setpoint.

I think the reason this string
DEBUG HEX2 Hours,":",HEX2 Minutes,":",HEX2 Seconds,CR
prints the time value is because the values of those variable are
held in these declarations.
Seconds VAR Byte
Minutes VAR Byte
Hours VAR Byte

but I can't find a way to use Hours:Minutes:Seconds to trigger the
event.

can anyone help?

I've learned a lot from just reading on this site and appreciate all
the work that everyone is doing to make the site such a useful tool.'

thanks

This should be a piece o'cake. If you have the time successfully
stored in the variables, here is one approach. You have to remember
that time is HEX:
IF hours=$07 AND Minutes=$30 THEN DEBUG BELL

I like to convert the time into a continuous variable that goes from
0 to 1439 for the minute of the day, or 0 to
14390 for ten second resolution.
julian = hours.nib1*10+hours.nib0*6+minutes.nib1*10+minutes.nib0

In that scheme, 7:30 am is 450
IF julian=450 THEN DEBUG BELL

-- Tracy
