atmega168v - avrusb
Posted: Fri Sep 12, 2008 8:25 pm
Hi!
I've just started to playing around with uC-s, and i got some pieces of atmega168v (low voltage, 10mhz top version ), so i'm trying to make work the avrusb example projects on one of these chips using a 12mhz external crystal and i belive fuse bits are set correctly (actually i'm not sure it should even work at that freq, should it?). The problem is, when i'm connecting the usb cable to my pc, windows says it's not recognizing the connected usb device and i should reconnect or change it. Unfortunately i don't have the equipment to decide if the uC works correctly with the 12mhz crystal so i don'T even know where to find solutions....so if you have any idea whats the problem pls help me....
Thank you
