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.
AVR - Doper is only HVSP
Re: AVR - Doper is only HVSP
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?
Re: AVR - Doper is only HVSP
I'm afraid no. Simon prefers this type of schematic.

Hello, As what I've known it only supports ISP and certainly no HVPP.
Re: AVR - Doper is only HVSP
There are two hardware versions. The big one supports HVPP, as far as I know.
