Hi,İ am currently using an 8051 and i am looking for a code and schematic about decimal counter using four 7-segment displays.(the counter should count up and count down).Thanks...

 

I will save Hero999 the time.

8051.. Hum, must be a school projects. I doubt I have any of them, but the schools probably do..

Is this a school projects? Blondie? Would that get all the guys here helping you fast? First post huh?

 

please elaborate more,

can you use BCD to 7-segment decoders?
do you want it to count like a stop-watch? or just count each click on a button?

Are you using a chip based on the 8051 technology like the 89c51.? which one?

it is just decimal counter.(0000-9999)

no,not stop-watch,just count each click on a button.

i am using atmel 89c52.

 

well things are simpler than i though then.. actually i don't have any code an schematic for that exac task in my hands righ now,

But in an article i wrote about frequency meters, i explain how to control 4 7-seg. displa using a 89C52:

this should give you an idea about how to connect 4 segments on only 1 port of the At89C52...

You should construct a simple schematic of your project to start with, then we can help and give advices.
