TkInter – obsługa silnika krokowego w Pythonie

[David36]

Stworzyem prosta aplikacje w tkinter - Python do sterowania silnikiem krokowym ale potzrebuje pomocy z kodem, chodzi mi o zmienne (kroki, szybkosc i przyspieszenie) pobierane z suwaka. Nie jestem pewien jakiego rodzaju zmiennych tutaj uzyc. Chce sterowac ta aplikacja z raspberry pi kod Arduino poprzez serial port. Dolanczam kod, moze komus sie kiedys do czegos przyda.
