B blondie4032 New Member Dec 13, 2006 #1 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...

mramos1 Active Member Dec 13, 2006 #2 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?

ikalogic Member Dec 14, 2006 #3 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?

B blondie4032 New Member Dec 14, 2006 #4 it is just decimal counter.(0000-9999) no,not stop-watch,just count each click on a button. i am using atmel 89c52.

ikalogic Member Dec 15, 2006 #5 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: **broken link removed** 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.
