I'm taking a Digital Concepts class right now and one of our final assignments was to create a 24/12 hour clock. I have both clocks finished except for one small thing. The teacher wants a switch set up so it can change between 12 and 24 hours with with either a button or switch. Ive been racking my brain for about 2 weeks now and for the life of me CANNOT figure this thing out, its very frustrating.

I'll attach the work i have so far. Im using Digital works and have the install if you guys need it (only like 3 megs)

Thanks for any help thats available!

 

Hello,

I am not able to run the program.
Please post a screenshot with the schematic in .png format.

Sorry about that, i didn't think otherwise.

Like i said, i have the actual exe that you can install with if anyone wants it

Edit: That button on the bottom is to pulse the clock (the instructor doesnt want to sit there and wait for it haha)

 

Hello,

Did you see this thread by Bill_Marsden ?
Digital Clock Block Diagram

thats pretty awesome, but i dont really know how to read this haha sorry.....

I don't know what goes into making each counter

Edit: the program im using doesnt allow me to set frequencies, just a clock pulse. Looking at that diagram i couldn't tell you how to wire this thing at all.

 

Heres the install for that program (scanned it before i uploaded) just so you guys can maybe get a feel of what i have to work with
