\"FTDI_err\"<\/a>Mo\u017en\u00e1 jste na to u\u017e tak\u00e9 narazili – posledn\u00ed aktualizace Windows (po 1.10.2014) p\u0159inesla i aktualizaci ovlada\u010d\u016f FTDI.

\nTo, \u017ee jste se stali ob\u011bt\u00ed FTDI \u00fatoku lze poznat pom\u011brn\u011b snadno – po p\u0159ipojen\u00ed Arduina se neobjev\u00ed s\u00e9riov\u00fd port, ale sel\u017ee instalace softwaru ovlada\u010de jak je vid\u011bt na tituln\u00edm obr\u00e1zku tohoto \u010dl\u00e1nku. Vzhledem k tomu, \u017ee ji\u017e do\u0161lo k p\u0159eps\u00e1n\u00ed EEPROM nepom\u016f\u017ee ani p\u0159einstalace star\u0161\u00edch ovlada\u010d\u016f, co\u017e n\u00e1m ale nezabr\u00e1n\u00ed v proveden\u00ed n\u00e1sleduj\u00edc\u00edho postupu:<\/p>\n

Pro uji\u0161t\u011bn\u00ed nejd\u0159\u00edve najdeme za\u0159\u00edzen\u00ed, ozna\u010den\u00e9 jako FT232R USB UART (Start->Ovl\u00e1dac\u00ed panely->Syst\u00e9m->Spr\u00e1vce za\u0159\u00edzen\u00ed).<\/p>\n

Pokud v\u0161e souhlas\u00ed, tak skute\u010dn\u011b nov\u00e9 ovlada\u010de modifikovaly obsah intern\u00ed EEPROM \u010dipu a p\u016fvodn\u00ed PID p\u0159epsaly. Uzav\u0159eme tedy okno Vlastnosti a otev\u0159eme jej znovu. P\u0159epneme se na z\u00e1lo\u017eku „Ovlada\u010d“ a klikneme na tla\u010d\u00edtko „Aktualizovat ovlada\u010d“.<\/p>\n

\"FTDI_8\"<\/a><\/p>\n

Po odsouhlasen\u00ed um\u00edst\u011bn\u00ed vybereme instalaci USB Serial Converter<\/p>\n
