It’s been a big pleasure meeting you! You have been doing a great work and I would like to also contribute to it.
I am a valve enthusiast designing valve based devices. You can have a short reference by having a look at my DIY website www.vampaudio.gr.
I am planning to design a big motherboard that will host:
HD USB DAC
Dual mono DAC
Individual Power Supplies
Tube output stage
Main controller: AVR
Digital signals multiplexed and manipulated by FPGA
My main questions regarding Volumio are:
- What type of I2S is the output of Raspberry Pi?
- Can volumio act as UPNP/DLNA player/renderer, so that I can send music through DLNA apps (eg. Bubble UPNP)?
- Can you output ID3 tags in UART (TXD), so that I can collect these data from AVR microcontroller?
- IR receiver will be connected to AVR microcontroller. Could Volumio receive commands by UART (RXD) for basic functions such us next/previous/play/pause?
I am willing to design this PCB and share it with you afterwards. Are you willing to support in some minor software points that may pop up in volumio side???
Hope that I will soon find enough time to develop this project as I believe it will be a really high end all in one digital audio playback device!
