cl249099, what drivers did you use with W7? What build do you have? (or anyone else who has Arduino working with W7)
I'm having troubles connecting my Arduino (Duemilanove) to my W7 (build 7022) laptop (Sony VAIO FW11E).
When I plug it in the TX and RX leds blink rapidly couple of times and then the pin 13 led starts to blink (4 blinks, little pause, 4 blinks...). So I guess the board itself is ok?
The W7 realizes that there is a new hardware and I've tried with couple of different drivers for the USB Serial Port "device". It always seems to install properly (to COM7) but the Arduino-0013 software can't upload anything to it. I've selected the Duemilanove board and COM7 from the tools menu so that should be in order. Also the code (Digital->Button) compiles correctly.
The error that the software gives:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
