No, firmware is not open source, for now at least.
Debugging ports are exposed on the board so it's theoretically possible to load your own code.
In practice, there are actually 3 firmwares: one for the micro-controller and one for each DSP core. Which firmware would you be specifically interested in?

I've rarely seen such mutual agreement on a prospected feature, so I suppose I'll push this in However, content of the forthcoming release is locked so it will take a bit longer until this is made available.

That's cool because it gives us time to discuss the details.
We could link channels one by one so into pairs that any change made on one channel would also reflect on the other channel. This would impose following channel pairs:
- ch 1, ch 5
- ch 2, ch 6
- ch 3, ch 7
- ch 4, ch 8
- ch 9, ch 10

The other way to implement this is, as Pascal suggested, to copy settings from one channel to any other.

Indeed, although I don't really recommend this because it's easy to make a mistake and end with an invalid file.

Hi Nicolas,
About linking channels: why not doing that way:
"link to channel:" and box where you can select the channel you want to be linked

Yes, I know I'm asking a lot... sorry

I'd just like to be able to play with the hardware, so as a minimum I'll need the basic drivers.
Is a schematics available, or at least a list of devices with addresses etc.?

I finally had some time to put things together

Click the image to open in full size.[/URL]

And it works... Unfortunately, I couldn't get my nice OLED display (which was left over for another project) to work. It has the exact pin-arrangement so I thought I would give it a try, but it was totally black and no sign of life at all. So I went down to the local store and bought a LCD display. For some reason however, there was no backlight at all so it's really hard to read. I checked the backlight supply pins and it seems to be in order (5V). Then I noticed that the maximum voltage for the background light was 4.5V according to the data sheet...so perhaps I killed it!?

I've been playing music using Airport Express as source (optical connection) during the day and I think it sounds very very good!

However, I would really like to have a working OLED display so I just want to know if anyone has found a compatible one?

Best regards,
Mattias

Not that I have anything new to report but I'd still like to say that I am thoroughly impressed by the speed at which new software is released. Excellent work and a huge Thank You to Nick and his associates.

Hopefully I'll receive som bits and bobs today

That would not work that well. Channel one and five are both left channels.

I would prefer:
pair one - ch 1 and ch 2 (subs)
pair two - ch 3 and ch 4 (midbass)
and so on.........

yeah +1, but to get equal load on core 0 and 1 it is the best to have the other version (1-4 for one channel and 5-8 for the other). The load on my cores are exactly the same with this setup.

best,
Paal

It'd work just fine. Channel 5 is what you want it to be. Left, right, sum or diff.
