    Hi to all ,

    Need help with AVR ISP systems.
    Plz allow me to inform that Its my first time using AVR ISP's (newbee) .
    As i am using a Laptop , its lacks an LPT port or a Com port , which is very much required to program Atmel chips i suppose.

    I am planing to use either one of the following ,

    1) USB to DB9/DB25 Adapter

    2) USB AVR ISP.

    Any kind of help/advise/recommendations will be deeply appreciated.

    If you plan on getting into AVRs seriously, get a USB ISP programmer. If you can spend the money buy the official programmer, the AVR ISP MKII. If you want to go cheap, Sparkfun, Pololu and Adafruit sell budget USB programmers.

    What are the benefits of the AVR ISP MKII over the budget USB programmers?

    One main reason is that the MKII is constantly updated to handle the latest AVR devices. Any budget programmers can handle the standard 8-bit megaAVR/tinyAVR line, however the MKII can handle a lot more. For example, when the XMEGAs were released the firmware of the MKII was updated for PDA programming of the XMEGA.

    If you are only programming the devices specified in the datasheet, then yes it should be fine.

    If you have the money I would go for a USB programmer. The best thing is to get a programmer that is supported by the chip manufacturer. So you can receive firmware updates and support for new MCUs

    Why not build a usb programmer? I am using this one http://www.fischl.de/usbasp/
    You do however sit with the chicken and egg situation, you need a programmer to build this. But, it's a simple circuit to build, provide you use the right zeners.
