in this program...if i press PIN_A5 the program of 24 hours will run but if not the program of 12 hours will run..but it still not working but when i remove all the part that im not sure the program of 12hours clock will run..

and can you please help me also to make a program for stopwatch and assign a designated switch..?

Do you have the pin configuration of your h/w i mean if you are using 7 segment how it is connected to portb.

i used led but it is like a 7segment common cathode...all positive connected to PORT B while all negative connected to PORT C...do you have a yahoo messenger?

a(0x01)
b(0x02)
c(0x04)
d(0x08)
e(0x10)
f(0x20)
g(0x40)

No I dont have yahoo messenger. I will make the code but first i need to study it properly.

I have not simulated the program but the scan of LEDs takes 6 x 15mS (=90mS) to complete which is far too slow. The display will flicker badly. Try changing the 15mS delays to 2mS or even 1mS.

Brian.

what is the use of Port A.

port A are connected to 4switch

**broken link removed**


you can also see my scheamatic in this site,..the 1st schematic is my circuit that i make but i change something because i used common cathode,...you can see in second schematic how the transistor connected in 7segment common cathode

That means Port a is for adjusting sec , min , hour, & mode.

absolutely

YES...

yes...but i dont know if it will run...

im not sure for those part of 24hrs but when i used only the 12hours programs it will run...but for 24 hours nothing happen...can you please help me..

to build a program...for that...or i have some option here

1st....12hrsclock with stopwatch

or 12hrs clock that can become a 24hrs...what do you think?

what do you think?

Click to expand...

learn to comment on your code so YOU know later on what it is about.

I have made small modification in i/p configuration as a0: min, a1: hr, a3: sec, a4: mode.

Now just change the h/w confg compile and simulate the code I hope it will run if it is giving still problem then betwn function of 12 & 24 hr use some nop.

but can you please help me for some part of a program?
