I have tried to get the 50$ robot micro-controller to work now for weeks I can't get past the point where both UI's (Linux & Windows 64 bit) tell me the lil piece of crap can't connect to program. It passes the smoke test fine and AVR Studios 5 reads the 5.1V but no device ID. The one I built, like in the tutorial, and the breadboard version I made both do this. I am using the avrispmkII and it says 2 green lights are go lets do this. Then when I try to upload anything or tell the programmer to read the device it fails or when I tell it to read fuses and such it fails. The only thing it does is sets the ISP freq. to 250 kHz and read the voltage level. I so like hardware oriented CPU's like the 6800 family processors. What happened to those and why do we have these pieces of crap that can't do anything without me being a C programmer ? Ok, ok so I am a little bit tired, does the 328p need a separate boot loader when used on the 50$ micro-controller since there is no ext oscillator ? I am going to breadboard a diff chip up and see if I can get one to do anything but sit there and mock me.
Take Care,

Have you tried AVR Studio 4? I want to say I've heard this to be a problem in the past (using v5, I mean), but couldn't find such a thread just now.

Yeah I tried AVR Studios 4 twice , 5 twice also tried Linux's avrdude and Audrino suite software with no luck.

You should double check all your connections and solder points as well.

Try reducing the speed of the AVRISP MKII. Seem to remember that its max speed is about one eighth of the CPU speed. For the $50 robot the default clock speed is 1MHz. So try dropping the ISP fequency down.

Nope, you can still use the AVRISP.
