Hi, I have an Arduino Duemilanove that don’t upload:mad:. It was working yesterday! Today, even my computer don’t reconized the Arduino as USB devise (in french is: périphérique USB non-reconnu). What can cause that:confused:
I use a PC with:
]Windows XP service pack 3/:m]
]intel pentium D CPU 3.4GHz/3.4GHz (dual core :p)/:m]
]2.0 Go of RAM/:m]
]Arduino 0016 (for windows)/:m]
]6ft male-A to male-B USB cable (they work with my external HDD, and yesterday with my arduino)/:m]
my arduino is bolted on a aluminum plate with three 4-40 bolt and nut and nylon post so they don’t touch any conductive surface. the power Led turn On when I connect the USB cable. When I try to upload, both Tx and Rx Led flash one time then the Rx led turn off and the Tx look like they are only half-power.
can you help me??? thank
they work now. some one understand somthing??? Me, I am lost. I only try, desconect USB, conect USB and retry.
So, thank every body:p I cross my finger for it continu working.
the probleme is back:mad:
again, they upload normaly. some time it don’t connect properly some it work just like it supost to do. I don’t understand and it very frustrant. when you want to change a line in the program, you don’t want to pass 1 hour to upload it in the arduino.
they ar the only thing that don’t work on my computer so I am thinking reordering a new arduino. Can I use the ATmega328 along without the board (on a breadborad)???
Have you tried uninstalling and reinstalling the FTDI drivers? Is your USB cable providing good contact?
Yes the Arduino can be created using the Atmega328 with bootloader but a mninimum circuit is required, which you can determine from the reference designs:
arduino.cc/en/Main/Hardware
Another possible fix:
If you are re-using the USB cable and plugging/unplugging it into different devices or other COM ports, the settings in Arduino (software) may not be saved. When you start the software, ensure the correct COM port is selected in the menu, as well as the right microcontroller module (ATMEGA328for the Duemilanove).
Hope this helps,
they work now. some one understand somthing??? Me, I am lost. I only try, desconect USB, conect USB and retry.
