Hello,

I bought the 8x8x8 LED cube kit from Hobby Components, assembled it and it is happily running away with whatever demo software it came installed with.

I now want to re-program this and am having issues uploading from the Arduino IDE.

I am using the demo code from the bottom of this post viewtopic.php?f=58&t=1968 which compiles ok but I get the following error message:

Sketch uses 13472 bytes (43%) of program storage space. Maximum is 30720 bytes.
Global variables use 123 bytes (6%) of dynamic memory, leaving 1925 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\\.\COM7": A device which does not exist was specified.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I am using the supplied USB cable to connect to the P1 serial connector on the board. In the IDE under the Tools>Port setting, I only have the option of COM7 so I have this selected.

Does anyone know what I need to do to download to this kit?

Thanks

The first thing to check is if you have the correct driver installed. The one that gets automatically installed by Windows is broken and although it will show a COM port, it doesn't work properly. To check this open up device manager, find the entry for the com port and see if there is a yellow caution triangle or error message associated with it. If so follow the instructions on in the first post of this thread under the title 'WINDOWS 8/VISTA/10 USERS':
