Hi to all, I would like to build an AVR - Doper, but I don't understand if the programmer support the HVSP (High Voltage Serial Programming) and the HVPP (High Voltage Parallel Programming) or only the HVSP.

Thank you for your suggestions.

It supports HVSP and ISP only, not HVPP. There are not enough pins on the ATMega8.

AVRMiniProg has a variation which can do HVPP, see http://www.simonqian.com/en/AVRminiProg/

Thank you christian for your suggestion, is there a schematic more clear of this programmer?

I'm afraid no. Simon prefers this type of schematic.

Hello, As what I've known it only supports ISP and certainly no HVPP.

There are two hardware versions. The big one supports HVPP, as far as I know.
