How it works
Using simply AND and OR gates are connected to several inputs a, input b, input c, input d, input e
The goal is to get a 8-bit binary value into a 7-segment display decimal
How to test
| input a and b | output a and b |
|---|---|
| 0 0 | 0 1 |
| 0 1 | 0 0 |
| 1 0 | 0 0 |
| 1 1 | 1 0 |
| input c | output c |
|---|---|
| 0 | 1 |
| 1 | 0 |
| input d and e | output d |
|---|---|
| 0 1 | 1 |
| 1 0 | 1 |
| 0 0 | 0 |
| 1 1 | 1 |
