More info: http://www.cburch.com/logisim/\n\n## How to use ?\n\n### Step 1\n\nFirst of all you will need to download the this project (link),  or clone.\n\nThen create a new circuit pressing \"CTRL + N\".\n\nSee:\n\n![1](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/how-to-1.png)\n\n\n### Step 2\n\nRight click at your circuit folder, go to \"Load Library\" \u003e \"Logisim Library\" then find the \"7-segment-display-drive.circ\" file\n\n![2](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/how-to-2.png)\n\n\n### Step 3\n\nAfter loading the library, you need to add the component to your circuit.\n\nIt's easy to see down in the list, the component:\n\n![3](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/how-to-3.png)\n\n### Step 4\n\nMake your circuit, and remember the display pins are:\n\n![Display](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/display.png)\n\nSo, after connecting the Driver to the display, your circuit should look like this:\n\n![4](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/how-to-4.png)\n\n\n## Examples\n\nInside the examples folder, you can see some circuits:\n\n### Example 1 - Switch\n\n![Example 1](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/example-1.gif)\n\n### Example 2 - Flip Flop JK (Async)\n\n![Example 2](https://github.com/marceloboeira/logisim-7-segment-display-driver/raw/master/_res/example-2.gif)\n\n## Docs\n\nHere you can see the Truth table, that I used to make the circuit:\n\n| Hex | D | C | B | A |   | a | b | c | d | e | f | g |\n|:---:|:-:|:-:|:-:|:-:|---|:-:|:-:|:-:|:-:|:-:|:-:|:-:|\n|  0  | 0 | 0 | 0 | 0 |   | 1 | 1 | 1 | 1 | 1 | 1 | 0 |\n|  1  | 0 | 0 | 0 | 1 |   | 0 | 1 | 1 | 0 | 0 | 0 | 0 |\n|  2  | 0 | 0 | 1 | 0 |   | 1 | 1 | 0 | 1 | 1 | 0 | 1 |\n|  3  | 0 | 0 | 1 | 1 |   | 1 | 1 | 1 | 1 | 0 | 0 | 1 |\n|  4  | 0 | 1 | 0 | 0 |   | 0 | 1 | 1 | 0 | 0 | 1 | 1 |\n|  5  | 0 | 1 | 0 | 1 |   | 1 | 0 | 1 | 1 | 0 | 1 | 1 |\n|  6  | 0 | 1 | 1 | 0 |   | 1 | 0 | 1 | 1 | 1 | 1 | 1 |\n|  7  | 0 | 1 | 1 | 1 |   | 1 | 1 | 1 | 0 | 0 | 0 | 0 |\n|  8  | 1 | 0 | 0 | 0 |   | 1 | 1 | 1 | 1 | 1 | 1 | 1 |\n|  9  | 1 | 0 | 0 | 1 |   | 1 | 1 | 1 | 0 | 0 | 1 | 1 |\n|  A  | 1 | 0 | 1 | 0 |   | 1 | 1 | 1 | 0 | 1 | 1 | 1 |\n|  B  | 1 | 0 | 1 | 1 |   | 0 | 0 | 1 | 1 | 1 | 1 | 1 |\n|  C  | 1 | 1 | 0 | 0 |   | 1 | 0 | 0 | 1 | 1 | 1 | 0 |\n|  D  | 1 | 1 | 0 | 1 |   | 0 | 1 | 1 | 1 | 1 | 0 | 1 |\n|  E  | 1 | 1 | 1 | 0 |   | 1 | 0 | 0 | 1 | 1 | 1 | 1 |\n|  F  | 1 | 1 | 1 | 1 |   | 1 | 0 | 0 | 0 | 1 | 1 | 1 |\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarceloboeira%2Flogisim-7-segment-display-driver","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarceloboeira%2Flogisim-7-segment-display-driver","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarceloboeira%2Flogisim-7-segment-display-driver/lists"}
