hello Student,
no, routine cannot be so simple to obtain what you want.
2 problem in your routine:
1. it check a RAM location related to a patch (MTB). So it will not work if that patch is not installed.
In fw there are plenty of RAM time locations.
E.g. use the one used in hourly Beep
2.in r12 there is a variable number that is udpated every few second (or each minute), depending in which routine you insert it. So conditional code will never be sotisfied.
Use a different routine,e.g hourly beep one.
3.IHMO, to insert a delay it's better to use original fw built-in delay () routines... work perfect and saves a lot of bytes
BTW, why you always try to develop such a difficul patches, even if you are still a young patching student?
I myself didn't start with these (middle) difficult ones... they are for intermedied level patching students!
Bye
