What do I need to program an ATmega 168?

Question

I use AVR Studio for my compilation and c/c++ code (not arduino).So far I have used a Atmega 2560 development board provided by Nex robotix.

I have ISP programmers of the following sorts... AVRISP mkII USB Programmer and NEX AVR USB ISP STK500V2.

Now I need to do some programming on low end microcontrollers like ATmega 168 (28 pins). I just have the raw chip. Can I program it on breadboard,or must I buy a development board?

After programming the chip can I use it on breadboard with Vcc, GND and the pins I need for my application?

Answer 1

Yes you can do this no problem. I have a setup on my desk doing this right now. Follow this tutorial and it will explain it to you:

If you are running the new AVR Studio also watch this video to help get you setup:

(You will need AVRDUDE installed as well).

Answer 2

Your AVR ISPmkII will program your chip just fine. Application Note AVR910 provides the details. The pinout of your ISP header is:

Match those pins up to the pins of the AtMega168, and you should be programming the device straight away.

Answer 3

Yes you can program ATMega168 on a breadboard. It works just fine because I have done that in the past using ISP programmer. It is best to use a regulator for Vcc. I believe this chip works on 3.3V so LM2937 regulator would be good. I used AVR Dragon debugger which worked like a breeze.
