Simple project using 68K microprocessor

Hi,
I have been assigned to design a microprocessor based system that would
be able to test the functionalities of the flip-flop such as D flip
flop or JK flip flop

Input:1)switch to select between either D Flip-Flop or JK Flip Flop
2)output from the flip flop

Output:Display pass and fail on 2 digits seven segment display.If fail
display the pin number.

So,may I know on where can I get some references on how to design this
system?

How many parts in hardware portion that are required in this project?

Should I be designing the analog circuits that portray the behaviour of
the flip flop first?

If so, how am I going to use 68K microprocessor to know whether the
flip flops are working properly or not?

Thanks
Any ideas would be highly appreciated.

Assigned as a job, or as a homework project? This is not a 'beginner'
project, so you either need to take some preliminary courses or get
another job. From the tone and substance of your question, you have
not a clue about how to do anything like this.

Just what is your situation?

Hi.

Does whomever helps you with this get part of your paycheck or
academic credit?

Some references for you:

datasheets on D and JK flipflops.
www.fairchildsemi.com is one source

datasheet on 68K microprocessor: ask whomever suggested using that
in the first place.

Heh, if someone assigned me to such a job, I would find myself
another job for sure ;)

The 68k microprocessor is a dinosaur, and an absurd overkill for
something like this. The 68k architecture lives on in the very nice
ColdFire parts, but again are very much overkill here. If you want to
use a microcontroller, pick something like an AVR.

Silly me! Since the project specifically wants the 68K (a totally
inappropriate choice), it must be homework!

But the 68K was the assignment.

I change the topic..I will be doing project on simple logic gate tester
using 68K as my homework.Thanks :)

Do you have to use the 68000 chip, or do you have the choice which part to
use as long as it is part of the 68k family? If so, use something like
68HC331, 68HC332, 68HC340, or 68302. These are chips that contain the 68k
cpu core plus peripherials like timers, serial, and several port lines to
use. You only have to add memory, clock, power, and a level shifter for
rs232 to have it run. People even have ported Linux for these chips.

There is more than enough information on the net. Just read.

If it's homework and you haven't a clue where to begin, then either you
haven't been doing enough work, or you are incapable of understanding
the course, or your teacher is incompetent. And if a teacher has set an
assignment requiring the use of a 68k processor to test a logic gate,
then either the teacher is incompetent, or you have misunderstood the
question. Whichever is the case, you'll get on a lot better be having a
chat with the teacher than asking a newsgroup for help.

I wish I had internet when I was at school. Life would have been so
much easier. I wonder how many kids these days have actually read an
encyclopedia? I remember my folks having a bookcase full of
encyclopedias that they got given becuase they were to expensive to
buy..... I am not that old either.....

why is a 68000 specified - totally inappropriate and overkill for this
simple task

Hi Rina,
I think this may be a trick question. You can make a tester
for for the flip flops with just switches and seven segment displays.

Hi all who replied to my message

Let me clear this up.This is exact what my lecturer told me in the
class.
Assignment:to design a microprocessor based system using 68K that would
be able to test the functionalities of the logic gate such as AND ,OR
,NOR or other.

Input:Output from the gate
Output:Display pass and fail on 2 digits seven segment display.If fail
display the pin number.

She told us that we needed to find the circuit from any sources
available i.e the internet,books or we have to design it on our own.

We are very confused since this is the first time we have been
introduced to microprocessor.We so far learned the architecture of the
68K,how to write program using assembly language and also 68230
interfacing.The hre comes the project...some sort called mini project.

We are asked to use 68K microcontroller and 68230 PI/T for
interface(PI/T is provided in the lab)in this miniproject.I have a
circuit w/o 68K in it that is used to test NOR gate output.So can I
create another circuit using 68K to extract circuit output to be the
input of the 68K circuit which then could be interface with the 68230
PI/T?Thanks

Any ideas would be highly appreciated.

People have already said you should be asking the instructor for
clarification.

But maybe this is one of those bogus tests, to see what you've caught
on overall design. A CPU is overkill for the testing, so either the
goal is to build the microcontroller (and the gate testing is just
an excuse), or it's to get you to decide that it's overkill.

There may be a misunderstanding about '68K'. It may not be the CPU, and
I don't suppose it's 68 kelvin or a 68 k resistor either.

Perhaps it's a massive cluster of some kind.

68K seems an odd number for a cluster. I'd have chosen 65537,
one extra for the console. With such a cluster, and proper
software, you can test more than one FF at a time. That is good
news.
