Making AVR Doper - Questions

Post by therock » Tue Apr 01, 2008 3:49 am

Hey !!
yesterday i came across AVR Doper circuit diagram. I think its worth a try. So today i bought necessary components(as of - http://www.rototron.info/?Page=USBAVR/USBAVR.ASPX ). but, As i am new to AVR i've some stupid questions.
1)ATMEGA8 - which bits must be cleared ??(i have pony-stk200 so i will be downloading firmware from ponyprog )
2)how can i use it through winavr ?? (i.e. what should i specify in make file ?? or how do i've to modify avrdude config??

For the fuse bits open Makefile in an editor and have a look at the fuse values described there.

On Windows, you can use AVR-Doper in CDC mode and it behaves as if it were an STK500v2 on a serial port. If you use avrdude, you can also set the jumper for HID mode and tell avrdude to talk to an STK500v2 on port "avrdoper".
