| Tester logických obvodov 7400 a 7493. Diagnostický report cez sériové rozhranie
| | ToDo |
| | |
| | |
| Záverečný projekt predmetu MIPS / LS2023 - '''Erik Szegi'''
| |
| | |
| | |
| == Zadanie ==
| |
| | |
| Tester logických obvodov- testovali sme, ako rýchlo dokážeme stlačiť tlačidlo po bliknutú kontrolky LED.
