popis:
Obsluzne rutiny pro displej 2x16 znaku s radicem HD44780
-Komunikace je ctyrbitova (pouzivaji se pouze piny displeje D4 - D7)
-Displej je v rezimu "pouze zapis" (signal "R/W" displeje je uzemen)
-Displej je pripojen k mikrokontroleru pouze signaly: RS, EN a D4 az D7.
Tento soubor vynikl upravou souboru "mojelib.h" jehoz autora bohuzel neznam.
