Simple project using 68K microprocessor

Aug 29, 2006 30 Replies

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.

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.

Cheers, Ed V.

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.

Rina

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.
