Hi guys, i'm Sebastian, from Argentina. I'm doing computer science in UNS.
I will do some examples of digital circuits this month and i can share it here.
My first exercise is to control seven-segment displays in several ways.
For this i will need MUX 8x1, MUX 4x1 , PLA & BCD Decoder.
If any one have any of this circuits are welcome else i will try to make them by my self

here is the circuit for 7 segment display, MUX are not implementer yet so i can't test it, also is attached all the information about who i arrived to the circuit using Karnaugh maps

Hi Sebastian,
Please download Digital Clock sample for 7 segment convertor from 4 bit input.
Also I am attaching a bunch of multiplexers as well as de-multiplexers.
You can simulate PLA with RAM in LogicCircuit program.
Thanks,
Eugene

tks Eugene. I implement a 8x1 MUX using 2 of urs 4x1 MUX.
1st example is rdy. I also implement a BDC decoder 1 bit/4 output.

Almost finish with 7 seg display, i need to record this table into a ROM. the circuit shuld have 4 inputs & 7 outputs.

Dig a b c d e f g
0 1 1 1 1 1 1 0
1 0 1 1 0 0 0 0
2 1 1 0 1 1 0 1
3 1 1 1 1 0 0 1
4 0 1 1 0 0 1 1
5 1 0 1 1 0 1 1
6 1 0 1 1 1 1 1
7 1 1 1 0 0 0 0
8 1 1 1 1 1 1 1
9 1 1 1 1 0 1 1

i attach the progress.

This is very nice, waiting for you to finish the project.
By the way have you read help page about memory modules?

Tks to u & Chubu's help. 7 Seg Display Controlers Examples are ready.
Next step will be some examples with flip-flops. See u soon.
