Not, it is the reason, and I bet that is the same reason many people use it, because that header files cames on Atmel AT91 Lib.

Seems you didn't got what I meant.
Telling "we do it this (bad) way because we already have a header" is an excuse at best IMO if told that your way is bad. Other people using the bad way isn't a reason either. A company providing a header in a (IMO) broken way isn't a valid reason for not changing either. So I still stand by my opinion that "we have a header file" as a reason is an excuse at best.
If you want to catch me on IRC I'm usually around in the evening hours CET.

Hi,

Please don't think you're the one who should tell the world what to do or not to do, and try to make use of contructive criticism instead of dismissing it out of hand.

You're right, I wasn't first here, and I don't pretend to tell anyone what they should do... however, I'm an active developer of the "Rockbox Player" (whose name we'll change shortly) and I strongly thing that anyone wishing to collaborate in this project should ask the rest of the developers about their thoughts. I think it's a good gesture and it's one of the main ideas behind open source community: sharing things and helping one another.
Besides, I don't know what criticism you're talking about, I haven't seen any criticism from dkamin and that's not what I'm commenting about. I do like criticism, mostly if it comes from the kind of people that write here, who do have real interest and knowledge about the matter in hand.

At the moment you've basically forked Rockbox and are working on it in your own space, rather than attempting to bring your software work back to the core project (we could probably have much of your in-progress code in SVN as long as you've been trying to follow the Rockbox coding styles, etc). (...)

Llorean, I think you were talking with Alex Cantos, however I can explain this part. I am the only one working on porting the firmware and as that, I don't have time nor knowledge to make patches. Well, I just learned recently to make patches and all this technologies were new to me at begin of the project.

I don't think this is addressed to me, and if it is I don't really understand what's the context.
Sorry if I've winded someone up, but I just pretend to be fair.
Cheers,
Alex

So, is this new add on board suppose to represent the Calypso board? Maybe, you can use some of the code from "AT91SAM Internet Radio"?
I was wondering which audio chip did you go with? The wiki page states one chip, but you direct the digi-key site to a different chip.
Does anyone know where to find the page for the do's and don't on programming Rockbox?
Thanks

I read that "AT91SAM Internet Radio" application note. I am mainly using the AT91 Lib to understand how to setup SSC to work as I2S. Also the PDC (Peripheral DMA channel).
The guy from the ARM MP3/AAC Player is using the AT91SAM7S256 and the same DAC IC. The SSC and PDC peripherals of AT91SAM7S256 should be almost equal to the ones on AT91SAM920. But that guy is not using DMA interrupt...
Right now I have DMA interrupt working. I also added on the Rockbox TLV320 drivers the SPI communication. I am being trying to understand Rockbox audio drivers...
You can see here the DAC IC we are using and the schematic and board.

OK, let's go through things in detail...

Some examples :

How is that not telling anyone what to do?
--- Quote ---Yes, you should have started introducing yourself
--- End quote ---
You mean like you did? Telling people to introduce themselves properly in your first post is an example of perfect forum behaviour I guess?

Who says that everyone wants to collaborate on your specific project? People are free to do their own thing.

He proposed some hardware modifications, after which you basically told him to shut up.

Well, Alex Cantos did introduced himself on project wiki page, much before of this first post. And dkamin read that page before his first post, since is the page of the project, he couldn't know about the project details before reading that page.

Well, dkamin already assumed some guilty: (...) In looking back at my original post, I see that I did not use much detail (...). The only important is that everyone who wants to help, needs to get together, share the information and we all should manage our energies. Let's continue.
