the attachment is not working....
i need this file how you do 8bit binary to seven segment....
I could not find the original find the original files, but I found the basic circuit scribbled in a notebook.
Brief circuit description:-
Counters U1 & U2 are configured as an 8 bit binary count-down counter.
Counters U3, U4 & U5 are configured as a 3 digit BCD count-up counter.
Both are driven by the same oscillator.
When the control applies a brief pulse (on line A) to the PE inputs of all counters, the binary information at the parallel inputs of U1 & U2 is transferred into the counters.
The parallel inputs of U3 ~ 5 are connected to 0V therefore these counters are set to 0.
When A goes low, U1 & U2 start counting down and U3 ~ 5 start counting up.
When the binary counter reaches 0, Co goes low which stops the oscillator.
The BCD digits can be then taken from the outputs of U3 ~ 5.
Thus they can be displayed on 7-seg displays until the next cycle starts.
If you need more any help, just let me know.
