HELP: Arduino duemilanove help!!

[asmi]

Hi guys,

I just bought an Arduino Duemilanove with ATMEGA328P h/ever I can't upload anything at all using 0011 IDE. I have even downloaded the hacked IDE version for 328p chip, still unable to upload onto my duemilanove.

I have tried uploading mpguino code using the latest IDE and it was able to upload successfully. H/ever to my understanding, the code is non-compatible with the latest IDE right? Only works with 0011.

Basically when I upload it, the TX light just lights up. That's all. The IDE program will hang until I unplug the USB port.

Anybody experience the same thing? Is there any solution to it?

I'm no expert, but I believe you needed to use version 0011 due to memory constraints with the old atmega chip. With the newer chip you have plenty of memory and the new IDE should work fine.

Yeah, dude... Duemilanove is an official Arduino board. There's NO reason to use any sort of old, alternative, or "hacked" IDE to upload to it. Just go to arduino.cc and download the latest IDE.

Also, there are two versions of the MPGuino code floating around for some reason: an old version designed to work with the old ATMega168 chips (with 16kb Flash and 1kb RAM), and all current Arudino boards (and the latest MPGuino) run on ATMega328 chips (with 32kb Flash and 2kb RAM). I think the latest MPGuino code uses the ".cpp" filename extension, whereas the older, outdated code uses ".pde" I think.

In fact, I'm currently wiring up my Duemilanove on a test board to play around with some more code modifications... wiring it up just per the Wiki page (without injector/VSS, obviously), and using the latest IDE and my own customized MPGuino code.

I hope somebody can update the Wiki to fix that. Because that confused me quite a bit as well.

I'd rather use the ATMega328 chip.
