sir
i m trying to make a digital clock with RTC(ds1307) ,but i am getting a problem
to throw on seven segment.
i have tried to make this code in c and i get easily in lcd ,but i am unable to throw same value on seven segment.

plz if some one help me how can i throw value in sevensegment

how is your circuit connected with seven segment?
pls give details to solve the problem.
 
Hi,

you no need to use 4 BCD TO 7 SEG ic chips(4511). refer my circuit, it will help .

program guide:(multiplexing mode)
1: send 1st BCD data to 4511 and turn ON one transistor. and turn off all other
transistors.

2:send 2nd BCD data and turn ON 2nd transistor and turn off all other transistors

3:send 3rd BCD data and turn ON 3rd transistor and turn off all other transistors

4:send 4th BCD data and turn ON 4th transistor and turn off all other transistors

transistor will take care of the current for 7 segment, you can also use one resistor (47 ohm or 220 ohm ) at the collector pin to reduce the current.

i am using at89c51 uc,decoder 4511
seven segment (common cathode)
i am giving input to segment from decoder

Connect BI pin no.4 to logic high
BI low means blank output nothing will display.
for details refer data sheet of 74hc4511.
Thanx.

There are many ways to connect an seven segment display. what ever he is doing is ok until any body blindly copying. in his circuit there is small problem which i had mention. we should read data sheet very thoroughly.
Thanx for your help.

sir,
i have tried in proteus software and its working fine,

thanku sir

you are welcome
this is a very good forum. and pls make it better by sharing information which you learn after finishing your job.
Thanx.

What is "Proteus software" ?
 

this a software in which we can make hardware design and we can run our code on it.

i am using proteus proffesional 7.1
 

sir i need the programme.if u have not any problem plz sent it to me or us.
