led chaser pattern repetiton

Hi..
Where have you been for the last 9 months ?

If you post a Proteus simulation I might be able to find the fault,
but I can't do it from just your code.

Sorry..

Thank sir for reply.
actually I was busy with my job(i'm a banker), so i couldn't manage time to my learning,
I hope you n ajay sir will help me again.
the code n proteus simulation file are attached.
my testing design pattern is desgn8 in the code, so please ignore other desgn.

thank u sir in advance.

Proteus crashed when I tried to open your project.

Please try modifying your project in some simple way.
Re-save the Proteus file and post it.

Also post a screen shot of the Proteus layout.

Your logic is okay.
I think the problem is your circuit.

Transistor base resistors r13, r15, r17 etc are not needed, remove them.

Add smoothing capacitors to the input and output of the 7805 voltage regulator.
Say 220 uF or bigger each.

Let me know how you get on.

thank u sir for reply.
sir i have done as u mentioned above, but same result..
could software be reason behind this ???

I created a very basic simulation in Proteus,
just the micro, no other components.

Your hex file switched the pins as expected.

Are you testing in Proteus or hardware or both.

Yes sir i'm using both.

Do they both give the same result ?

Try this minimal version..does it work ?.
