# 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:

![1](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/how-to-1.png)

### 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:

![Display](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/display.png)

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
