Working on a controller for my dac.

I have an arduino controlling the dac and a web application communicating with the arduino.

The web application will have two views:
  1. current info eg volume, sample rate etc
  2. settings to setup/tweek the dac without reprogramming.


So far I have been playing around with startup volume, volume and mute and have the framework in place to start adding more functionality.

The settings ui is for now extremely basic :)

Web ui in the works

Added some power management features today.

Using the 3.3 v on the i2c header to monitor when the buffalo powers up. It allows me to keep things interrupt/event driven and lightning fast.

Next step, controlling the relay to power up the buffalo.

Have been playing around with mobile ui.

A simple volume control where i slide my thumb up or down to adjust the volume. Works really well:)


Mobile UI POC

Looks nice :)

Are you using the hifiduino code as well, or have you started from scratch (IOW no display / apple remote)?

Edit: If you can use the volume buttons on the side of the phone instead of the touch display that would also be great, as that makes it easier to adjust the volume without looking at the phone.

No i started from scratch. I needed a completely different architecture.

I agree about the buttons. Im not sure yet if that will be possible without writing a native app.

I did something similar using an application called NetIO. It simplifies the process somewhat as long as a reasonable connection is possible. Was hoping to generate ideas so I started a thread over at DIYaudio. http://www.diyaudio.com/...ed-audio-appliances.html

After a few iterations I have a generalized arduino solution with ir control.

Posted the code on https://github.com/fernfrost/Buffalo

Perhaps it can be of use to someone.
