hi
For days I'm trying to connect my AVR to PC via COM port but i couldn't
Device missing or Unkown device (-24)These r some suggestion which listed in web site :
A) programmer not powered up (check voltages)
I think it's powered up coz as i connect batteries the servo make a sound and vibration for less than 1 sec ( sth like 1 or 2 deg rotation)
-----------------
B) you are telling it to use the wrong port (check device manager)
I have 2 com ports and I've tested for many times
-----------------
C) you have another program running that is using the same port (close other programs)
i guess i don't have any special program (1 external 1000Gb HDD, )
plz some one help me what to do

by the way, do i need to connect sensors to be able to program the AVR or not ?
actually i've just connect : 1 servo + batteries
