#168588 - My working matrix schematic* Responding to: ???'s previous message |
Hello again, this is my working dip matrix schematic
*At least if I didnt any mistake during the drawing. I believe I will use this matrix instead of using any CI, because to make the matrix using single face board I would use many jumpers, and the added diodes is doing also the jumper work **OOPS, R1 is 4K7 actually  |

| Need more information | 01/01/70 00:00 | |
| It's olá ... | 01/01/70 00:00 | |
| ghosting? | 01/01/70 00:00 | |
| Looks like ghosting | 01/01/70 00:00 | |
| Do you have two spare pins? | 01/01/70 00:00 | |
| Please tell us how you've wired your matrix | 01/01/70 00:00 | |

| It looks OK, but... | 01/01/70 00:00 | |
| maybe, maybe not | 01/01/70 00:00 | |
| thats true | 01/01/70 00:00 | |
| External resistors for speed or reading slower | 01/01/70 00:00 | |
| noise, yes - but | 01/01/70 00:00 | |
| Different use of resistors | 01/01/70 00:00 | |
| I could be mean | 01/01/70 00:00 | |
| Was actually on topic ;) | 01/01/70 00:00 | |
| being off-topic or not... | 01/01/70 00:00 | |
| You need to show us the schematic and more | 01/01/70 00:00 | |
| he did | 01/01/70 00:00 | |
| Not quite enough | 01/01/70 00:00 | |
| not much code to show | 01/01/70 00:00 | |
=) Thanks for the +1 Informative =) | 01/01/70 00:00 |
