hi everyone, I had a problem about debugging programs in avr studio.I load the obj file created with codevision and run the simulator.I can see the general purpose registers and other registers' value, but the thing is when I drag a variable to watch window it says not in scope.

Hi, Try this one. http://www.lantronix.com/device-networking/embedded-device-servers Then click on either xport or wiport. You can get them from mouser http://www.mouser.com/lantronix/ And select the one you want. It's cheaper to buy a xport approx $50 American and buy a wireless
