Arduino Mega - com port

[bonatius]

Ahojte,

neviem kam mam tuto temu spravne zaradit. Ak som ju zaradil zle, poprosim, admina nech ju zaradi spavne. Dakujem.

Mam takyto problem. Mam dosku Arduino Deumilanove a Arduino Mega a win7 x64. Ked pripojim k PC Arduino Mega, pc si ju najde a v Device managery jej priradi port COM9, potom otvorim vyvojove prostredie Arduino IDE, napisem program, vyberiem vyvojovu dosku a serial port (COM9), program nahram do dosky, ale ked odpojim dosku od pc a neskor ju opat pripojim a chcem nahrat program do dosky tak Arduino IDE vypise, ze serial port COM9 je pouzivany a uz mi nedovoli opat si vybrat port COM9. V Device managery mi vypisuje, ze tento port je priradeny pre Arduino Mega. Ked pripojim k pc Arduino Deumilanove tak mi hned ponukne serial port (COM6) a mozem nahrat program do neho. Ked ho odpojim a opat pripojim, tak hned s nim mozem komunikovat a vobec nevypisuje, ze serial port (COM6) je obsadeny. Ked restartnem pc a opat pripojim Arduino Mega k pc tak mi ponukne port COM9, ale ked dosku odpojim a neskor pripojim tak uz opat nemozem s nou komunikovat (port COM9 je pouzivany).
Da sa tento problem nejako vyriesit?

Dakujem za pomoc.
