7 Segment Display Driver

TTL-7447-like implementation for logisim

The 7-segment display driver is an implementation of or BCD (Binary Coded Decimal) to 7-segment display decoder and driver.

It allows you to send binary numbers to a 7 segment display rather than implementing every character yourself.

What is Logisim ?

Logisim is a circuit simulator. More info: http://www.cburch.com/logisim/

How to use ?

Step 1

First of all you will need to download the this project (link), or clone.

Then create a new circuit pressing "CTRL + N".

See:

Step 2

Right click at your circuit folder, go to "Load Library" > "Logisim Library" then find the "7-segment-display-drive.circ" file

Step 3

After loading the library, you need to add the component to your circuit.

It's easy to see down in the list, the component:

Step 4

Make your circuit, and remember the display pins are:

So, after connecting the Driver to the display, your circuit should look like this:

Examples

Inside the examples folder, you can see some circuits:

Example 1 - Switch

Example 2 - Flip Flop JK (Async)
