Tester logických obvodov 7400 a 7493. Diagnostický report cez sériové rozhranie
Záverečný projekt predmetu MIPS / LS2023 - Erik Szegi
Zadanie
Tester logických obvodov- testovali sme, ako rýchlo dokážeme stlačiť tlačidlo po bliknutú kontrolky LED.
Literatúra:
Analýza a opis riešenia
Najprv sme pripojili LCD displej s tlačidlom a LED diódou
Algoritmus a program
Algoritmus programu je....

Overenie
Na používanie našej aplikácie stačia dve tlačítka a postup používania je opísaný v sekcii popis riešenia. Na konci uvádzame fotku záverečnej obrazovky pred resetom. Vypísaný je tu priemerný čas a najlepší čas.
