Corpius, very nice documentation!, Congrats.

Have you also included the possibility to control more than one Buffalo?
I have an active multiway system and I'm using an Arduino with GLT firmware to control two BII
I would like to switch to your system but would like to be sure if your firmware can handle two Buffalo

If glt's firmware can do it than mine should be able to do it too. It's based on his work. How are you using glt's firmware exactly? What have you done with it to control your two BII's?

well, it's long time I'm not updating the code. I'm a little bit lazy so I'm sticking on ver. 09g of GLT code and can't remember well what if any mod I've made to the code.
The main job is to issue any write command to both address 0x90 and 0x92
At that time GLT have made some change to his code upon my request.

Thanks Rich. The ce328 firmware is also suitable for your system. You'll like it's interface. Much nicer than the version you got from me earlier on.

thx. I'll do my best, but I can't compete with you. The amount of information you're publishing is simply amazing. Where do you find that much time??? If it wasn't for you I would have struggled much more with controlling the es9018.

One of my next projects would be to create some code for my two OPUS DAC's. I'm planning to build a integrated amplifier that includes the OPUS DAC's in dual mono. I want to have analog inputs as well, so I'm still looking for some ways to achieve these. Perhaps a miniDSP or something would the trick. Any suggestions maybe?

So basically you're writing all commands to the registers of both DAC's. That's more or less the same as setting it to dual mono, exept for the mono part of course how about the DAC polarity? Anti-phase or in-phase?

Corpius,
I tried to purchase your controller but could not get your shopping cart to work. I am sorry to waste bandwidth here but I could not even contact you through your website. I registered under the name xluorp on your website.

A wolfson would be great, would be nice to be able to select all filters and dithering at every sample rate.

Wen you say mini-dsp do you mean for oversampling or for active crossover?

Brilliant work Robert!

I forgot to mention on my here and on my site that some additional libraries are needed to work with the firmware. I added this info to my site:

In order to use the code the LiquidCrystal library from F Malpartida and the RTC library from JeeLabs both needs to be used. Download them both. Unpack them and replace the original LiquidCrystal library by the new one in the libraries folder of the Arduino software. Copy the RTC library folders and files to the libraries folder. Restart the Arduino software for the changes to take effect.

• New LiquidCrystal
• RTClib

You got a PM.

Well I have not been doing some proper investigation on the miniDSP products, but I assumed that I can use them to take both analog and digital signals and use it for volume control. Perhaps a descent analog volume control is better.
