My Arduino UNO won't upload any sketches anymore, it has worked before, but now it just stopped working.
This is the error message it gives me: avrdude: stk500_getsync(): not in sync: resp=0x00
This is the error message it gives when holding down shift: avrdude: usbdev_open(): did not find any USB device "usb"
When uploading it the LED on pin 13 turns off, and the RX flashes 3 times. The TX stays off.
I'm using Windows 7 64bit, and I have also tried it on a Windows 7 32bit machine, with the same results.
I am also sure I have the right COM port selected, and that I have the correct board ticked under Extra --> Board
The sketch I last used with the Arduino was one for reading PPM signals, it was connected to my RC transmitter via port 1, and a ground port. It was sending back data to my computer, but suddenly it stopped. If you need to know any more info on what I'm using or what I was doing, don't hesitate to ask.
Thanks in advance!
