I am new in using the ARDUIO. I just bought the ARDUINO UNO, but I can't get a connection to this device.
I am using W7 64 bit. So I installed the driver (2.08.08 ) from the FDTI website. This works fine and I can find the ARDINO UNO in the device manager as “Ardunino UNO (COM3)” .
After this I am struggling with all further operation.
First I started to download a example sketch.
When tying to download, I getting this “Binary sketch size: 1010 bytes (of a 32256 byte maximum)”, but this is the last information for a while. By the way, the green LED on the UNO on, the yellow L is flashing, the RX and TX LEDs are always off.
Sometime I also get the message: “avrdude: ser_send(): write error: sorry no info avail”
thanks for the fast answer. I think I did everything well.
To double check this, uninstalled the driver and started again. I now installed the driver direct under “..\arduino-0021\drivers” (you mentioned, that the UNO need a different driver than the 328). After doing this, the driver is installed – but the driver can't be started (error code 10). So the diver has still a alert sign in the device manager.
What is the right software for W7 64Bit??? In the download I found the windows software, and below a link to 64Bit, but I don't know, if this means W7 64 Bit or Linux 54 Bit.
I had the exact same issue today and like ours HJB, it started working in much the same way yours did. Then I was able to load some basic example code and I thought everything was great! However, it failed again and I have also tried it on and XP machine, a Windows 7 32 bit and an Ubuntu 10.10 machine all with the same failure to connect. The symptoms are exactly as you describe.
If anyone can assist I would be grateful I don't want to buy a new board, especially if I don't know what caused this one not to work properly after connecting it for the first time today.
One again:
It is working for me, since I am now on a other USB port on my computer. When I am switching back to the previous one, it fails.
So I stiil assume, that the load on the USB port was the problem. So you should try this also.
I did try that. I still get intermittent failure. Interestingly though, I am able to connect occassionally to any given usb port on any of the afformentioned machines. So I now if I am able to connect long enough to load he code I do that and then disconnect. After that I use the 9v battery connection to run the solution. This will become an issue if I need to print output at any point as it just disconnects when ever it seems to feel like it.
