It wouldn't work for 3 years and suddenly think "geez, I'll stop working".

Mr xshax has probably not done something correct.

 

Why is so much "thank you" for something that does not work?

Trolling again, eh?

Those are really old.


But the answer to your question is ******* posting.


Take a look at the number of posts they have. They signed up on the forum to say thank you then went away. Go figure.

 

if anyone have counter project (working) plz post here.....!

 

Why not show us what you have done instead? I suspect this project works, if it is verified it does not then it will be removed.

Pictures of both sides of the board would be good, and how you programmed the PIC. Have you experience in making PIC projects before, or is this the first one?

 

i made this circuit accurately,then write the hex into pic16f84a. when i give the supply nothing will happen.i measure voltages of 1,2,3,4 those are positive.but the question is how common cathode displays are work. is there anyone here work this project.....!

I would not be too sure about past behaviour of some unknown circuit.
Maybe the battery had run out, and nobody replaced it. So it stopped working.

 

You're not understanding what's going on here.

OK, then where are the pictures? It is possible someone can spot something you missed.

Looking at the schematic I do not see the power supply pins on the PIC. This is not good.

 

Guys

This is a really old thread. Xahax hijacked the thread. Bertus created another thread here

http://forum.allaboutcircuits.com/showthread.php?t=76476

for Xahax yet the Xahax can't seem to understand to post in that thread only. Xahax is posting in both threads. In the other thread Xahax is expecting someone to create the OPs project.

Since this thread is so old, can it just be locked?

How can someone not understand the basic concepts of a forum yet want to be able to create a relatively complicated project like a pic operated counter?

BTW did not mean the other posters trying to help, I meant Xahax. Just wanted to make that clear.

 

I will not close this post because there will be other questions from other folks, but any further posts from xshax on this thread will be moved to his thread. It is assumed this is a working entry, since many other people have commented on how much they liked it.

For xshax, a thread belongs to the original poster, who in this case would you.

http://forum.allaboutcircuits.com/sh...ad.php?t=76476

Lets keep any further comments over there please.

 

can u send me the source code please...

 

profahmet has not been on for a year, and the thread is well over 4 years old. Please start a new thread in the projects forum, I doubt you will get any help here.

 

Here's the source code:

Power pins on the ISIS simulator is normally not shown. Has to look up on the datasheet. I did the simulation again and it does work...

Allen

 

Smart Alec.

 

thank you so much my friend..it helps a lot to my project

 

brilliant, interesting project

 

sorry for inconvenience. this is my first time to do this. does it really need a ISIS simulation in order to work this counter? i don't have any idea. i'm already done but it doesn't work.. whats the purpose of ISIS simulation??? please give me some idea on what else i can do just to work this counter...please thank you

 

what if i use 3 seven segment and the count is only 0-999??? what is the program... tnx..

 

why the program is not working with the MPLAB?
