is the truth table done correct? is it only the kmaps not correct?

I haven't looked at your truth tables, but since you came up with K-maps similar to the one I did, is say they seem okay...

 

these slides i got from my lecturer notes

One of the flaw in those counters is that they start at 1. Both slides say: start at 1, count to 5, 1->2->3->4->5->1.

You need: start at 0, count to 23, 0->1->2->....->23->0

Your counter needs to be:
0 (midnight)
1 (1am)
2 (2am)
3 (3am)
.
.
.
11 (11am)
12 (12pm)
13 (1pm)
14 (2pm)
.
.
.
22 (10pm)
23 (11pm)
0 (midnight, return to the start of the table)

 

OMG ^.^ i think i got that AhA moment im getting it!!! Thanks so much i have until friday and now i feel some hope. i really appreciate everyone's help.

You can't do a 5-variable K-map like that. See here for how to do one.

 

ok awesome so for the times that i need for the clock, should i put a 1 in the box or should i derive it from the truth table. im still having a hard time. sigh, im going crazy.

 

also should i do a decoder for the switch, should it be a 0-31 with 4 or 5 bit and 0-7 D

 

It sounds like you are allowing yourself to get distracted by things you'll need to do in the future. Take a small break and come back to it remembering that everything depends on what time it is.

At the moment, you need a Mod-24 counter(counts 0 - 23), which ends up requiring 5 bits. This counter, once you have it, will be the basis for everything later, so give the counter your main focus. Make the counter, the rest will come after..

Look at the modulus counter thread I linked earlier, that should help you.

 

here is the first 2 kmaps http://gyazo.com/6f97234feb92bd96f119daea185eac86

You should show the state transition take so we know what your reasoning is...

 

jeez im on a short time i cant take no more riddles.

http://gyazo.com/9a0e8181e8917827a4c70a2539d262d8 think this is it

 

The state transitions for your counter....

Simply looking at a K-map means someone has to go back and figure out why you put a 1 in a certain cell, where if you were to supply the state transition table, you wouldn't force someone to recreate your work just to check it.

I don't have time for riddles either. You need to convey your process more clearly.

but i already link u the truth table, doesnt that show it?

In a convoluted way, yes, however, the state table shows what the current count is and what the next count should be, that way, we can see what your input-forming logic should be to make that count. As is, you have the current count and the next count's input-forming logic, making us have to rework the logic to verify what you want. This takes time and requires us to pay attention to make sure you didn't make any mistakes.

 

oh ok let me know when you are done. Thanks alot Sir, this means alot to me, all your help.

 

i got an extension im so happpy now i can more time to get everything done. ok here are the links to the simplification of the kmaps.

You are using the overlay method of a 5-variable K-map, which means you can't do the grouping like the following:

The Gray Code style K-map is where you can group along an imaginary mirrored border, but you have used the overlay method.

See the difference in methods here.

 

oh ok so should i change to gray code or group these differently?

Whichever you'd like; either way, you must be aware of the grouping requirements.
