hej
Jeg har en LED-matrix, der virker fint
Hvordan ville jeg cascade det, og vil dette behov for eventuelle ændringer i mit program

Firma zobowiązała się do wypłacenia rekompensaty wszystkim osobom, które w trakcie pracy w zakładzie zachorowały na raka i inne poważne choroby.



Kwon Oh-hyun, dyrektor naczelny Samsunga, poinformował, że firma nieprawidłowo oceniła sytuację swoich poważnie chorych pracowników oraz...<img src="http://feeds.feedburner.com/~r/dobreprogramy/Aktualnosci/~4/qTNXCcH7LSI" height="1" width="1"/>

hi;
godt om den hardware jeg bruger et skift register (hfe409bp4) en aktuel sinker (Toshiba uln280AG) og 8 PNP transistorer
Jeg får de oplysninger og uret fra mikrocontroller

koden er i c avr codevision compiler:[# define SETBIT (adresse, BIT) (ADRESSE | = (1 <<BIT))

dette førte til en matrix nu, hvordan man cascad det til en anden [/ code]
