I've been using a Robostix for quite a while now but for one reason or another it has stopped letting me ISP new code to it, I'm using AVR Studio 4 which gives me the 'ISP MODE ERROR' window when I try to download code. The code already flashed on there works fine when I power it up though! Could it be a fuse problem? When I go to the fuse page none of the boxes are ticked and the bottom window says 'fuses address 0 to 2... 0xFF, 0xFF, 0xFF'.
If anyone could provide any help or advice whatsoever I'd be extremely grateful.
