Hi !
I'm currently trying to make a customized arduino board. I just bought an ATMEGA328P-20PU for my card.
I wanted to test it on the Duemilanove before, but without any bootloader, I can't do anything.
I have a PIC programmer here, but I wasn't able at all to get some information if it's possible to write the bootloader with a PIC programmer (and how to) instead ICSP.
I'm quite good in electronics, usually, but I have some difficulties in programmation.
Thanks a lot,

I just figure out that my PIC programmer has also ISP interfacing.
What's the difference between ISP and ICSP ?
Can I use the ISP interface of the DataMan programmer on the ICSP port of the Duemilanove ?
Thanks Again,
Adrien
They use different programming algorithms.
The AVR is actually simpler to program. Making a PIC specific programmer work with AVR would not be a fun task.
Making a PIC and AVR programmer as a new project with very few parts is possible.
You can even program an AVR with a parallel port and 3 resistors, although it is not the safest programmer.
You might want to look at: PonyProg - Serial device programmer
Not very expensive for parts... free software.
If you have a PICKIT programmer... then you only have a programmer that can program PICs.
Dataman programmers can program AVR's with the right adapters.
Thanks a lot for your answer. Now I understand what really is an AVR chip.
While waiting for it, I made a very very ugly parallele programmer thanks to this webpage : http://arduino.cc/en/Hacking/ParallelProgrammer
It worked well for burning one time.
So I guess my PIC programmer is totally useless for any Atmel microcontroller.
I give the AVR designers a LOT of credit for realizing the benefits of keeping the chip programming easy.
